No ... this will never happened. Because they produce only products for us with limited lifetime and flickering. I build my own lamps with LED-Modules from China, some Ceramic and Electrolytic Capacitors and an LED Powersupply. I have reduced the voltage of the powersupply too, so that the voltage is limited. If a line of LEDs of one line in the LED-Modules will break, then the current on the other LED-Lines in the module would be increased (cascade effect) ... this would be not good. (there are several parallel lines with some LEDs in the line) With the limited voltage, the Module will not destroy themself in such a situation. The other LED-Lines in the module will get the same current even if one line is cut.
Amazing you can fit so many components in to a candelabra base. Too bad they are not available elsewhere, the random failures and short life gives LED bulbs a bad name.
from what I observed, the designs of most LED bulbs are designed with just meets components rating. So thermal aging leads to early failures. The LEDs themselves seldom fail, and if ever they do, could be attributed to component tolerance.
Using components below specifications often elongates their lifespan beyond belief. For this reason we used to lower the filament current of radio valves by a few percent, back in the day.
I designed a lot of control gear for navy ships and it used filament bulbs for indicators. We ran them at 15% when they were 'off' and 85% when they were 'on'.
@@JezCunningham Which takes away most stress of heating up and cooling down. This brings me to a set of 25 watt incandescent bulbs in a cupboard, that I put in series. The lights were on each night for over 20 years. They never broke down.
I would kind of like to see how the device deals with those "unfavorable conditions" such as over voltage, under voltage, spikes, etc. Maybe do that to the 2W bulb to see how 'robust' the design is?
We have been watching the UAE Tour. I got very excited when I noticed one of these bulbs in the studio behind the presenter. Nobody else understood why I was interested in a lamp :-D
One of the features they're touting for these lamps is the low heat output to save on air conditioning costs. In a place where you run a/c all year round that could be significant.
ive heard people disputing the energy efficiency claims of standard led bulbs in europe/the west since you need to turn up the heating a bit since youre not getting the 100watts you used to get from a lightbulb but in the case of airconditioning i can see that being a big saving, especially in large open areas like shopping centres, hotels, restaurants and that
@@apm136 Those claims are way overstated. It's way more efficient to get your heat from a well positioned heater than it is getting it from a lamp. You have no control over your incandescent lamp's heat output (negating any winter savings in the summer, and what if you want to stay warm in the dark?) and their positioning (mostly near walls and ceilings) make them less immediately useful. LEDs are better period. And since it's 2021 and basically no places use incandescent lighting anymore, the savings potential isn't even that great. In case of the Dooby lamps, you'd save like 2W per 2W lamp compared to ordinary LEDs or 7W relative to CFLs... That's nothing in terms of heat. Humans give off 100W, average heater radiators give off 1.5kW+ depending on size. And even if you would have a higher heating bill while reducing your electricity bill with efficient LEDs, I think in most places heat is cheaper than power so you're never gonna lose
Dubai has a rather well-earned reputation for being hot, and doing round-the-clock construction both on land and in the Gulf. Burnt-out bulbs requiring constant replacement that might halt construction would constitute a royal pain the the balls, so underdriven LEDs that could survive much longer at higher temperatures would be a boon for the booming city-state.
I imagine that the reason why Philips was so keen to jump on this project was that, at some point in the early 2000s, Dubai was conservatively estimated to have 15-25% of the entire world's population of construction cranes. It's not that these bulbs are industrial, it's that these are the consumer-grade ones being brought to market alongside the ones that I'm sure are being sold en masse to Dubai's monolithic construction industry.
Unfortunately the idea is that "Made in China" = cheap crap. Of course, China is able to make good stuff if you are willing to pay the price, but few people are interested in expensive stuff from China.
@@gubx42 Yes, true and it would take a brave manufacturer, but the market is global its pretty much without competition - providing the manufacturer realises that the attraction is longevity and power savings.
The price is going to be 2x-3x for the 3x-4x materials used, which will which lasts on average 4x as long. Everything is running at a lower temperature, there is more fault tolerance. The Arrhenius equation would apply "As a rule of thumb in most biological and chemical reactions, the reaction rate doubles when the temperature increases every 10 degrees Celsius", or flipping that in reverse: Every 10 degrees Celsius drop in temperature, doubles the mean time to failure (basically hot stuff breaks, cold stuff lasts a long time).
@@gubx42 I'm thinking there are a few brands which are already trusted enough that they could take a stab at it, because obviously it's a marketing exercise because tech is trivial. One is Xiaomi which is a phone conglomerate that also makes everything. Another is maybe Anker or someone of a kind. Furthermore they have the advantage that Chinese government is known to be able to be convinced to fund things and take away commercial risk when a case is to be made that it's of strategic importance. I think it's much more likely that China mandates Dubai-efficiency lamps before EU does, a billion lightbulbs can save a shit ton of energy, and energy might just make or break China in the upcoming years. And if they do standardise such lamps, odds are, they will spill over.
The great thing with a company like Philips is they're not limited by what components are available when deigning consumer products, because they can make whatever they need in-house (in their component factories), or at least they could when I worked for them. I was a Philips engineer for 13 years, and we could order Philips parts for in-house projects from our other factories. I once asked our purchasing guy to order 4 small special diodes for a prototype board. About a month later a forklift arrived carrying four rolls of diodes for a component insertion machine, a total of 4 million diodes. Our purchasing guy had accidently entered an incorrect digit in the part number. We contacted the diode factory and offered to send them back, but they told us to keep them.
You seem on your usual good form to me Clive! Trouble is, because you mentioned you recorded it while feeling less than fresh, one tends to look for stuff that probably isn't there. The power of suggestion so to speak. Very interesting as usual. Thanks!
Nice video. Quietly professional. Shows professional respect for the excellence in concept, design and implementation Impressed with your smooth pronunciation of 'Sheikh Mohammed bin Rashid Al Maktoum'. Agree there are about 3 or 4 moments where you are struggling very slightly for the correct words but I think it adds a pleasant human element. Given it is likely to be a fairly popular video it may be worthwhile having a go at redoing the reverse engineering but I am undecided if a razzamatazz style reverse engineering would be better or worse than the mellow effect you have already achieved. Difficult decision (especially hard when you are spending hours overthinking every aspect) . Have a go and see what you end up with??? (Needless to say, don't be afraid to keep the original version even if the new version takes days to 'polish')
please use FLIR camera on a working circuit. My limited understanding links longevity of electronics with heated components. It is reassuring (to me) to show what can be done if design is not compromised by other factors (greed).
I like the current regulating arrangement on that lamp. Simple, easy to understand. It seems to me that it would limit the current to a set voltage across those resistors regardless of what the capacitive dropper is doing. That means it would probably be even more efficient at 230V than at 240V.
I just realized that natural gas forced into tubular cylindrical flames would have the same result in a larger size would be insane efficiency. Thank you Clive 🤘😎🤘❤️
Only question is when Philips will start selling them in Europe. I tried to get an answer from Philips but no luck. Pity really, I want to buy these lamps!
@@ingenalls1721 EU will not because in democracy corporations own government. in monarchy, chad monarchs can dictate corporations and you get beautiful environment friendly things like this bulb
Can you get your friend to give you a few more of these which I might barter from you, in exchange for some of my dangerously badly made electronic devices? 😉
I definitely agree, but we probably won't see bulbs like these anytime soon. They're just too efficient and long-lasting, they'd lose too much profits.
When I buy a "Guaranteed 5-years" lamp / bulb I mark the receipt number on the base THEN scan the receipt onto my computer. WHEN (NEVER IF) the lamp fails less than the guaranteed life time, I contact the manufacturer and demand a FREE replacement. I haven't bought a lamp for years! Legislation would bring these Dubai lamps onto the market - the only trouble is the politicians get bribed not to.
In the early days of the Singer Sewing Machine company, they almost went out of business because they made their sewing machines so good that no one needed to buy a new one. This was because they don't wear out and were easily repaired. I think what saved the company was when they were starting to include electric motors on their new machines, they offered you a great deal if you traded in your old machine.. They promptly melted down the old machines and made cheaper, less reliable machines.. and the company was saved. Philips could go out of business producing lights that don't need replacing.
@@crytocc It's certainly does. It tells me that it keeps people employed and people continually upgrading to new , better, safer, devices. Disposable products can be looked at as a bad thing or a good thing. Imagine if cars were made the way the Dubai lights are? We'd all still be driving around in 1970s vehicles spewing all kinds of crap into the air. Sometimes getting rid of old stuff and replacing it with new stuff has advantages. And even with our less efficient LED's they do improve over time. I've really not had ANY reliability problems with pretty cheap LED light bulbs purchased at home improvement stores. I think the ones I'm currently using are 60 watt equivalent, I believe they are 7 or 9watts actual consumption. I think I bought 10 in a box for $12, 5 years ago. They're all still working. I think the biggest issue with disposable products is ensuring that the junk is recycled properly. And doesn't just end up in a landfill or dumped in the ocean.
Clive, the metal bases of most LED lamps I have disassembled are crimped around the base of the bulb. I find that a straight blade micro-screwdriver can be used to losen the crimping. Then the whole metal peice can be easily removed. (After removing the plug in the tip too)
Tip from me, when you try to open a plastic LED bulb.. First remove small cap from the bottom, Second, use a solid Bakelite E27 Fitting as a grip to pull the E27 Cap, the 2017 LED tend to be easier to open rather than the older type.. Third, put Paint Thinner / Isopropyl alcohol around the Bulb Cap Diffuser to ease the Silicon Glue.. Then use a mini CPU pry bar to remove the Bulb Cap Diffuser.. Also use isopropyl Alcohol to ease the silicon Glue inside the Bulb.. Then, use a long small diameter steel bar, put it inside from the bottom hole.. Put it around the corner of LED Heatsink inside and knock it with a hammer.. Tralala, you can open LED Bulb, and reclose it tightly using Silicon Glue and hammering the E27 Cap using a Nail or a Tungsten Pen..
Like they care about the environment :) you remember all the reduce plastics marketing they were pushing? Well do don't want to know the details. It was strictly forbidden to attack plastic packaging , that's why everybody attacked those happles straws and plastic bags , even though the biggest amount (and the most dangerous for your health) of plastic is in the packaging
Talking to Phillips with a big government stick in your hand might be more efficient. Basically, the existence of these is proof positive they CAN make better lamps in bulk at their factory.
TAKE APART THE 2W BULB!!!! As someone who is just getting into this stuff as a hobby, it’s nice to see how the circuit board components scale with power rating. Cheers!
200 lumen per watt is pretty crazy efficient. When I recently searched for new bulbs ~130 seemed to be the best you could get, but I also looked for something much brighter. Maybe only dim bulbs like this can be efficient.
_I can see clearly now that the _*_drain_*_ has gone..._ The 12V / 24V Zener diodes are there to protect the MOSFET from overvoltage as it is likely that it is a 30V device. Considering the circuitry, it would have been more beneficial to use the same type NPN transistor for current regulation... From what I've observed, linear regulators and MOSFETs don't mix very well. A reason they would have chosen this arrangement is because of the low gate drive current; but because of the extremely low (6mA) current, the base drive current would only need to be 30uA which would be easily filled by a 2MEG resistance at 300V.
The video seems completely fine Clive. I would not have noticed you were under any such duress. .. Would be nice to understand the regulation circuit a bit better. Like what regions the MOSFET operates in. I’ve measured the total efficiency of the ReactorMicro constant current chips at ~75% which is v poor relative to the BPsemi non-isolated buck chip bulbs which are >90%. I’m very curious whether this circuit is any better.
As you stated that's what light bulb companies do they design them to last a specific time to maximize profits they conspire with each other to make sure they don't under cut each other without harming each others sales but since to prove conspiracy you have to show an exact meeting that they conspired to do this.
Just wish I could buy these. The crappy Amazon Brand candle ones we have run at 5W and 90°C, and die after a few months. Infuriating that there's something objectively better that I can't buy.
@@outcastatsabre Oh we've Philips ones elsewhere. They don't die but they're still very warm, and often dimmer than I'd like. And imagine the light output on one of these cranked up a wee bit.
We used to use a rectifier disk that we dropped into the light socket before we screwed in the incandescent light bulb. Mainly for barns and outside lights. They would run half power and would last for a VERY long time. Many of them ran all the time or from dust to dawn. I'm sure they had a flicker but it never really bothered me. Also, we would get 150 volt light bulbs that would run longer on 120 volt systems. Too bad we can't do that with the LED bulbs.
Only problem with a half wave rectifier in series with a lamp is it screws up the operation of RCD/GFI. The rectifier produces an imbalanced current which saturates the detection coils and prevents them tripping when you get hold of a live wire.
@@DjResR Yes, I remember the "50 year night light" hawked in some of those mail order catalogs in the 60's and 70's. Two 7 watt christmas tree type bulbs in series.
@@quantumleap359 That is interesting. I used the same trick in early 2000's with cheap chinesium bulbs named "Impulss" and extended the lifetime from few weeks to years so the claim is not that far fetched either. How long did these nightlights actually lasted?_
@@domnik9062 I did in fact built one, and even though the circuit works as it should, it was flickering for some reason. Current limiting circuit works perfectly, it can be that the bulk cap I got is actually a lower capacity than it says, as increasing the value of the series capacitor either did nothing or blew the fuse resistor. Also it could be that the 220V RMS mains voltage is just a bit low. Modding cheap LED bulbs was more successful for me. You can also doobyfy the bulbs like bigclive did in a later video, that also works.
I know there was a video done by him I am sure and I can not find it. I know he added another capacitor in series with the led bulb. He did some tests as well
Given the lamps are such a precious commodity (at least, outside Dubai?) I'd say leave the 2w unit alone. Having said that, if something interesting comes up about that zener diode, it'd be neat if you could pass that along. 👍
You just made me realize something: over here we only have "Edison" lamps (E10, E14, E27, ...), though we don't call them like that, since we only have those available (no bayonets in sight), and I often wondered where the "E" stands for; I guess now I finally figured it out (after all these years).
@bigclivedotcom I have a Question out of curiosity. Is there some kind of "protection" gas inside the lamp or just normal air? We got some cheap LED lamps (not sealed but with a plastic diffusor) here and just yesterday one of them popped. After opening it, I could see that the capacitor was bloated (but still sealed) and the resistor was the one that popped. The other lamps on the fixture were still on after that popping. At the same time the Lightswitch got "stuck" and stopped functioning (clicking). Inside the Lightswitch there was black soot and some black stuff was on the contacts that felt like a dry mixture of soot and grease. The reason the lamp popped was definitely rapid aging due to overheating, since the fixture uses glass bowls with the open side pointing down. The age of the LED lamp was less then 6 months.
@@gucky4717 Not really. It's just electronics, which is almost never housed in any kind of gas atmosphere. Incandescent lamps need an inert gas to prevent the tungsten filament from combusting in the extremely high temperature it gets up to. In LED lamps, the glass and filament arrangement is mainly just for looks.
@@tybofborg They often use helium in the glass filament envelope because helium has high thermally conductivity. Cooling is essential to maintaining lifetime and efficiency. The filament arrangement serves a practical purpose because it allows the emitters to be angled down towards the base. Compare this to plastic-based lamps where the emitters all point upwards. A uniform light distribution is a key metric on LED standards, e.g. Energy Star.
I've been wondering what might be possible with those "DIY LED lamp" kits from eBay/AliExpress, since I have some of those kits in a box. Even if they were only used as a convenient source of a lamp base - though I imagine you can find bare lamp bases on AliExpress as well. Replace the supplied power supply PCB with something custom - maybe along the lines of what Philips have done here - and solder a load of LED filaments together... I don't think they'd fit under the clear plastic dome of those lamp kits, so something else would be needed unless you wanted live parts exposed :) A 3D-printed cover could work, and would offer a bit/a lot of diffusion as well, depending on the plastic type and print settings (PMMA and PETG are probably the best bets for light transmission, but you still won't get anything properly "clear"). Or maybe it's an excuse to learn glass-blowing? :D

I have my bedroom a hanging lamp with three E-14 lamps in candle shape. On my last purchase in a remaining stock market, I found heavily reduced OSRAM filament LED lamps with 4 filiaments each and a rated power of 4W. I purchased three of them. They are pleasingly completely flicker-free, but for the place of use really too bright. What's closer than, to Dubai-I-ficate them? In a test buildup I found out, when I add a 1μF capacitor in series to the whole lamp, I can make the three LED-lamps down to 1W each. Perfect!
Isn't there some cheap eBay knockoff of these, for us regular people who don't live in Dubai to buy? My most economical (and still quite bright with a decent amount of lumens) 220V E27 IKEA LEDs are 4.3W. Would love to go to 1W!
I'd really love to find something comparable for 120v. I'm getting sick of flickery ones that bake themselves to premature failure, seemingly regardless of brand or price.
I wonder which would be the thing to finally kill these, the electrolytic drying out or the phosphor on the LEDs getting so degraded that the light quality goes to crap. Either way it's going to last a fair bit longer than your typical lamp.
Fascinating circuit. I will steal that voltage regulator idea one day. Yes, it would be a tragedy to destroy that exceedingly rare and clever big Dubai bulb. It's a keeper.
The current regulator is a discrete version of the linear regulators used in many lamps these days. What's novel is that they have combined two current control methods.
@@bigclivedotcom I guess I should have said "ripple regulator." Modulating a MOSFET with this secondary control could be handy. it could easily (easy to say that) be tuned with a little trimmer pot.(sure, could use an actual regulator but they can get hot)
Wonder how hard it would be to try and get some of these bulbs into Canada, probably harder than necessary but there's just too many things about these dubai lamps that are so much nicer than regular led bulbs
So there is an opening in the market for making LED bulbs with double the normal filament? If phillips wont do it some other company should. Then advertise as more reliable than other brands with 'high temps'
hrm... i wonder how feasible it would be to "clone" these lamps using off the shelf components (including regular dome LEDs) and using a larger sized bulb as case (to not have to minimize as heavily). not considering that it would involve making and fiddling with bits and pieces that will be live at some point :P
Open Notice to Any Manufacturer: Make these for everyone. If you produce them with the same quality and engineering you could $€££ them for whatever price you need to and you would still $€££ millions of them.
Wouldn't be too difficult (at all) to modify the Chinese existing LED PSUs in this way. Probably will need a little experimentation on component values but would nevertheless be a very worthwhile project perhaps?
Hi Clive, Totally off-topic. I'm looking to run mains electricity to my new shed. I was going to use the twin-and-earth that currently runs a faulty motion-sensitive lamp, rather than getting someone to install a new spur. What'd be a good jointing option between a twin-and-earth and an armoured cable I can bury next to my lawn? Thanks, Simp.
Nice teardown, shame we can't buy these. I'd definitely buy some knowing that they are super efficient and would last much longer. Also yes I would love to see the 2W lamp teardown, complete the set of teardowns :)

It's not that these bulbs are industrial, it's that these are the consumer-grade ones being brought to market alongside the ones that I'm sure are being sold en masse to Dubai's monolithic construction industry.
It's amazing what a company will do for you if you own a Country. :)
its also interesting what corporations can do if they own the politicians by lobbying lol
It also same as you can't get random chip/component to repair phone or laptop or some other random appliance.
@@lordjaashin Too true.
If Philips won't sell them to the rest of the world, then perhaps an enterprising Chinese manufacturer will?
Unfortunately the idea is that "Made in China" = cheap crap. Of course, China is able to make good stuff if you are willing to pay the price, but few people are interested in expensive stuff from China.
@@gubx42 Yes, true and it would take a brave manufacturer, but the market is global its pretty much without competition - providing the manufacturer realises that the attraction is longevity and power savings.
The price is going to be 2x-3x for the 3x-4x materials used, which will which lasts on average 4x as long. Everything is running at a lower temperature, there is more fault tolerance. The Arrhenius equation would apply "As a rule of thumb in most biological and chemical reactions, the reaction rate doubles when the temperature increases every 10 degrees Celsius", or flipping that in reverse: Every 10 degrees Celsius drop in temperature, doubles the mean time to failure (basically hot stuff breaks, cold stuff lasts a long time).
@@gubx42 I'm thinking there are a few brands which are already trusted enough that they could take a stab at it, because obviously it's a marketing exercise because tech is trivial. One is Xiaomi which is a phone conglomerate that also makes everything. Another is maybe Anker or someone of a kind.
Furthermore they have the advantage that Chinese government is known to be able to be convinced to fund things and take away commercial risk when a case is to be made that it's of strategic importance. I think it's much more likely that China mandates Dubai-efficiency lamps before EU does, a billion lightbulbs can save a shit ton of energy, and energy might just make or break China in the upcoming years. And if they do standardise such lamps, odds are, they will spill over.
The great thing with a company like Philips is they're not limited by what components are available when deigning consumer products, because they can make whatever they need in-house (in their component factories), or at least they could when I worked for them. I was a Philips engineer for 13 years, and we could order Philips parts for in-house projects from our other factories. I once asked our purchasing guy to order 4 small special diodes for a prototype board. About a month later a forklift arrived carrying four rolls of diodes for a component insertion machine, a total of 4 million diodes. Our purchasing guy had accidently entered an incorrect digit in the part number. We contacted the diode factory and offered to send them back, but they told us to keep them.

Impressed with your smooth pronunciation of 'Sheikh Mohammed bin Rashid Al Maktoum'.
Agree there are about 3 or 4 moments where you are struggling very slightly for the correct words but I think it adds a pleasant human element.
Given it is likely to be a fairly popular video it may be worthwhile having a go at redoing the reverse engineering but I am undecided if a razzamatazz style reverse engineering would be better or worse than the mellow effect you have already achieved.
Difficult decision (especially hard when you are spending hours overthinking every aspect) .

@bigclivedotcom: This is the anti migraine LED light that can replace a filament bulb. Could be export product #2 for the country! Well, perhaps :-)
Amazing what they’ve done with jellybean parts in such a tiny space. So clever and efficient in every way.
please use FLIR camera on a working circuit. My limited understanding links longevity of electronics with heated components. It is reassuring (to me) to show what can be done if design is not compromised by other factors (greed).
I like the current regulating arrangement on that lamp. Simple, easy to understand. It seems to me that it would limit the current to a set voltage across those resistors regardless of what the capacitive dropper is doing. That means it would probably be even more efficient at 230V than at 240V.
I just realized that natural gas forced into tubular cylindrical flames would have the same result in a larger size would be insane efficiency. Thank you Clive

Nice one🐻🐨🐼😁
I'm all for testing more lamps. Especially ones readily available in Europe from decent brands.
Can you get your friend to give you a few more of these which I might barter from you, in exchange for some of my dangerously badly made electronic devices? 😉
I feel the low power radiating from this rare oddity . The world needs these for sure not just Dubai man.
I definitely agree, but we probably won't see bulbs like these anytime soon. They're just too efficient and long-lasting, they'd lose too much profits.
actually if you bought a 10w bulb and ran it at 7w it will last a very long time, you just need to change the dropper cap inside the bulb
When I buy a "Guaranteed 5-years" lamp / bulb I mark the receipt number on the base THEN scan the receipt onto my computer. WHEN (NEVER IF) the lamp fails less than the guaranteed life time, I contact the manufacturer and demand a FREE replacement.
I haven't bought a lamp for years!
Legislation would bring these Dubai lamps onto the market - the only trouble is the politicians get bribed not to.
Just gotta figure out how to increase the PF, and then we'll be golden

In the early days of the Singer Sewing Machine company, they almost went out of business because they made their sewing machines so good that no one needed to buy a new one. This was because they don't wear out and were easily repaired. I think what saved the company was when they were starting to include electric motors on their new machines, they offered you a great deal if you traded in your old machine.. They promptly melted down the old machines and made cheaper, less reliable machines.. and the company was saved.
Philips could go out of business producing lights that don't need replacing.
Which frankly tells one all that one needs to know about capitalism...
@@crytocc
It's certainly does.
It tells me that it keeps people employed and people continually upgrading to new , better, safer, devices.
Disposable products can be looked at as a bad thing or a good thing.
Imagine if cars were made the way the Dubai lights are?
We'd all still be driving around in 1970s vehicles spewing all kinds of crap into the air.
Sometimes getting rid of old stuff and replacing it with new stuff has advantages.
And even with our less efficient LED's they do improve over time.
I've really not had ANY reliability problems with pretty cheap LED light bulbs purchased at home improvement stores.
I think the ones I'm currently using are 60 watt equivalent, I believe they are 7 or 9watts actual consumption.
I think I bought 10 in a box for $12, 5 years ago. They're all still working.
I think the biggest issue with disposable products is ensuring that the junk is recycled properly.
And doesn't just end up in a landfill or dumped in the ocean.
thank you Clive. we now have all the information we need to start making our own lamps.
Clive, the metal bases of most LED lamps I have disassembled are crimped around the base of the bulb. I find that a straight blade micro-screwdriver can be used to losen the crimping. Then the whole metal peice can be easily removed. (After removing the plug in the tip too)
Tip from me, when you try to open a plastic LED bulb..
First remove small cap from the bottom,
Second, use a solid Bakelite E27 Fitting as a grip to pull the E27 Cap,
the 2017 LED tend to be easier to open rather than the older type..
Third, put Paint Thinner / Isopropyl alcohol around the Bulb Cap Diffuser to ease the Silicon Glue..
Then use a mini CPU pry bar to remove the Bulb Cap Diffuser..
Also use isopropyl Alcohol to ease the silicon Glue inside the Bulb..
Then, use a long small diameter steel bar, put it inside from the bottom hole..
Put it around the corner of LED Heatsink inside and knock it with a hammer..
Tralala, you can open LED Bulb, and reclose it tightly using Silicon Glue and hammering the E27 Cap using a Nail or a Tungsten Pen..
EU should ban bulbs that are NOT made like this. It kills our environment on so many levels.
Like they care about the environment :) you remember all the reduce plastics marketing they were pushing? Well do don't want to know the details. It was strictly forbidden to attack plastic packaging , that's why everybody attacked those happles straws and plastic bags , even though the biggest amount (and the most dangerous for your health) of plastic is in the packaging
These LED filament bulbs are far better than any other LED bulbs. It’s has the appearance of and incandescent filament bulb. It’s all I buy.
We gotta talk to that Sheikh and see if we can't make this the standard for LED lamps from now on!
Talking to Phillips with a big government stick in your hand might be more efficient. Basically, the existence of these is proof positive they CAN make better lamps in bulk at their factory.
TAKE APART THE 2W BULB!!!!
As someone who is just getting into this stuff as a hobby, it’s nice to see how the circuit board components scale with power rating. Cheers!
Those lamps looks awesome ❤️🤩
Sheik Ala Bin Big Clive supreme ruler of the Isle of Man
sounds like the ideal place to set up an illicit light bulb factory
200 lumen per watt is pretty crazy efficient. When I recently searched for new bulbs ~130 seemed to be the best you could get, but I also looked for something much brighter. Maybe only dim bulbs like this can be efficient.
_I can see clearly now that the _*_drain_*_ has gone..._
The 12V / 24V Zener diodes are there to protect the MOSFET from overvoltage as it is likely that it is a 30V device.
Considering the circuitry, it would have been more beneficial to use the same type NPN transistor for current regulation...
From what I've observed, linear regulators and MOSFETs don't mix very well.
A reason they would have chosen this arrangement is because of the low gate drive current; but because of the extremely low (6mA) current, the base drive current would only need to be 30uA which would be easily filled by a 2MEG resistance at 300V.
That’s impressively simple and effective. I like it.
Do those people not like seeing you pull apart globes with your bare hands, or your bear hands ... Hmmm, I wonder.
If Philips sold these globally I'd guess they'd be out of business in 10 years.
@User 2389 the lamps would not die, thus people dont buy new ones
@@DANGERTIM112 my lamps don't die either and don't require 2x the LEDs
The video seems completely fine Clive. I would not have noticed you were under any such duress. ..
Would be nice to understand the regulation circuit a bit better. Like what regions the MOSFET operates in. I’ve measured the total efficiency of the ReactorMicro constant current chips at ~75% which is v poor relative to the BPsemi non-isolated buck chip bulbs which are >90%. I’m very curious whether this circuit is any better.
The bulk of the current limiting is done by the cap dropper. The linear section operates in a small voltage range.
As you stated that's what light bulb companies do they design them to last a specific time to maximize profits they conspire with each other to make sure they don't under cut each other without harming each others sales but since to prove conspiracy you have to show an exact meeting that they conspired to do this.
Whoop whoop dooby time :D may start the dark and stormys now for the live stream later!
ElectroBoom did a video recently about these lamps
i think a glove is a good idea as the glass is often paper thin and can be broken very easy and can cut you really easy.
Next Big Clive will put the lamp back together! 😏😅😂😆🤣💡
Just wish I could buy these. The crappy Amazon Brand candle ones we have run at 5W and 90°C, and die after a few months. Infuriating that there's something objectively better that I can't buy.
Just don't buy the cheapest lamps?
@@outcastatsabre Oh we've Philips ones elsewhere. They don't die but they're still very warm, and often dimmer than I'd like. And imagine the light output on one of these cranked up a wee bit.
We used to use a rectifier disk that we dropped into the light socket before we screwed in the incandescent light bulb. Mainly for barns and outside lights. They would run half power and would last for a VERY long time. Many of them ran all the time or from dust to dawn. I'm sure they had a flicker but it never really bothered me. Also, we would get 150 volt light bulbs that would run longer on 120 volt systems. Too bad we can't do that with the LED bulbs.
Only problem with a half wave rectifier in series with a lamp is it screws up the operation of RCD/GFI. The rectifier produces an imbalanced current which saturates the detection coils and prevents them tripping when you get hold of a live wire.
Look for my dooby lamp video.
You can use two incandescent light bulbs in series to get massive lifetime. Unfortunately LED lamps don't work that way either._
@@DjResR Yes, I remember the "50 year night light" hawked in some of those mail order catalogs in the 60's and 70's. Two 7 watt christmas tree type bulbs in series.
@@quantumleap359 That is interesting. I used the same trick in early 2000's with cheap chinesium bulbs named "Impulss" and extended the lifetime from few weeks to years so the claim is not that far fetched either. How long did these nightlights actually lasted?_
Still waiting for some parts to make my own 3w ones. These lams are awesome!
I am planning to do so as well. Have you already accomplished your goal?
@@domnik9062 I did in fact built one, and even though the circuit works as it should, it was flickering for some reason. Current limiting circuit works perfectly, it can be that the bulk cap I got is actually a lower capacity than it says, as increasing the value of the series capacitor either did nothing or blew the fuse resistor. Also it could be that the 220V RMS mains voltage is just a bit low. Modding cheap LED bulbs was more successful for me. You can also doobyfy the bulbs like bigclive did in a later video, that also works.
@@VeeAyyDee Thanks, but i don't know which one you are referring to? The one where he cuts off the resistor?
@@domnik9062 I did a 3W variant of the Dubai Lamp
They can further decrease power consumption, by using an NTC instead of the 10 Ohm power resistor.
Clive, you might want to do a video on how to make these ourselves, thank you 👍
I know there was a video done by him I am sure and I can not find it. I know he added another capacitor in series with the led bulb. He did some tests as well
I just found it watch this ruclips.net/video/ISTB0ThzhOY/видео.html
Given the lamps are such a precious commodity (at least, outside Dubai?) I'd say leave the 2w unit alone. Having said that, if something interesting comes up about that zener diode, it'd be neat if you could pass that along. 👍
Why wouldn’t they sell these to the rest of the world at 2x the cost
They won´t until you point a gun at the Philips CEO´s head at point-blank range. Greed. Sad but true..
You just made me realize something: over here we only have "Edison" lamps (E10, E14, E27, ...), though we don't call them like that, since we only have those available (no bayonets in sight), and I often wondered where the "E" stands for; I guess now I finally figured it out (after all these years).
@bigclivedotcom I have a Question out of curiosity. Is there some kind of "protection" gas inside the lamp or just normal air?
We got some cheap LED lamps (not sealed but with a plastic diffusor) here and just yesterday one of them popped. After opening it, I could see that the capacitor was bloated (but still sealed) and the resistor was the one that popped.
The other lamps on the fixture were still on after that popping. At the same time the Lightswitch got "stuck" and stopped functioning (clicking).
Inside the Lightswitch there was black soot and some black stuff was on the contacts that felt like a dry mixture of soot and grease.
The reason the lamp popped was definitely rapid aging due to overheating, since the fixture uses glass bowls with the open side pointing down. The age of the LED lamp was less then 6 months.
For LEDs, they’re probably air.
@@JasperJanssen Yeah i saw in the Video that the lamp wasn't sealed airtight. But could it make a difference? :p
@@gucky4717 Not really. It's just electronics, which is almost never housed in any kind of gas atmosphere. Incandescent lamps need an inert gas to prevent the tungsten filament from combusting in the extremely high temperature it gets up to. In LED lamps, the glass and filament arrangement is mainly just for looks.
The glass LED lamps may use helium, but the classic plastic lamps are probably just ambient air.
@@tybofborg They often use helium in the glass filament envelope because helium has high thermally conductivity. Cooling is essential to maintaining lifetime and efficiency. The filament arrangement serves a practical purpose because it allows the emitters to be angled down towards the base. Compare this to plastic-based lamps where the emitters all point upwards. A uniform light distribution is a key metric on LED standards, e.g. Energy Star.
Clive " That's very interesting, (Allen Millyard "And that was perfect along with Tracy's cup cakes).
So now knowing the circuitry I guess you could make one big clive style. :-)
I've been doodling ideas like that in my mind.
I've been wondering what might be possible with those "DIY LED lamp" kits from eBay/AliExpress, since I have some of those kits in a box. Even if they were only used as a convenient source of a lamp base - though I imagine you can find bare lamp bases on AliExpress as well.
Replace the supplied power supply PCB with something custom - maybe along the lines of what Philips have done here - and solder a load of LED filaments together...
I don't think they'd fit under the clear plastic dome of those lamp kits, so something else would be needed unless you wanted live parts exposed :)
A 3D-printed cover could work, and would offer a bit/a lot of diffusion as well, depending on the plastic type and print settings (PMMA and PETG are probably the best bets for light transmission, but you still won't get anything properly "clear").
Or maybe it's an excuse to learn glass-blowing? :D
Is that a full bridge rectum fryer? They reduced the circuit size very well
I really hope that we will be able to get this lights come on China knock off market. 2x 👍

@@bigclivedotcom I much prefer the cool (or cold) white. Even in the bathroom, they give good color rendition, which I know some people don't like, but they tell the honest, although unwelcome truth about what you really look like!!
Cold white in this case means 6500K - much colder that 5000k Daylight. The color rendition is only 80 with a huge blue spike at 450nm.
Dealing with with glass is a grate skill to lurn
I have my bedroom a hanging lamp with three E-14 lamps in candle shape.
On my last purchase in a remaining stock market, I found heavily reduced OSRAM filament LED lamps with 4 filiaments each and a rated power of 4W. I purchased three of them.
They are pleasingly completely flicker-free, but for the place of use really too bright.
What's closer than, to Dubai-I-ficate them?
In a test buildup I found out, when I add a 1μF capacitor in series to the whole lamp, I can make the three LED-lamps down to 1W each. Perfect!
Isn't there some cheap eBay knockoff of these, for us regular people who don't live in Dubai to buy? My most economical (and still quite bright with a decent amount of lumens) 220V E27 IKEA LEDs are 4.3W. Would love to go to 1W!
Can you open regular EU phiips lamp and compare it?

Gentlemen, welcome to Dubai lamps.

Nothing wrong with the production, engaging and accurate as always. We don't want a BBC production perfect, Clive we want a human Clive :-)

which RF noise ? It's a "linear" current regulator
@@inotoff I don't know from the MOSFET turning on and off as it's going into the saturation point
I'd like to see the scope before and after the smoothing circuit
I wonder which would be the thing to finally kill these, the electrolytic drying out or the phosphor on the LEDs getting so degraded that the light quality goes to crap. Either way it's going to last a fair bit longer than your typical lamp.
If the electrolytic dries out the only effect will be increased flicker.
Philips if you are watching please sell them here
Someone should start selling kits to build these lamps on etsy :D
You have my vote to sacrifice the 2-watt specimen in the name of education👍🤓
Fascinating circuit. I will steal that voltage regulator idea one day.
Yes, it would be a tragedy to destroy that exceedingly rare and clever big Dubai bulb. It's a keeper.
The current regulator is a discrete version of the linear regulators used in many lamps these days. What's novel is that they have combined two current control methods.
@@bigclivedotcom I guess I should have said "ripple regulator." Modulating a MOSFET with this secondary control could be handy. it could easily (easy to say that) be tuned with a little trimmer pot.(sure, could use an actual regulator but they can get hot)
So glad I subscribed to your channel, I really enjoy watching videos that educate about subjects that I'm unfamiliar with.

Its such a shame to open those up, considering their not something you can just go out and buy. Oh well.

Wonder how hard it would be to try and get some of these bulbs into Canada, probably harder than necessary but there's just too many things about these dubai lamps that are so much nicer than regular led bulbs
recently an Australian posted 2 cans of beer to Canada youtuber "pileofstuff", he thought it wouldn't be legal either...
Best "RUclipsr" there is.
So there is an opening in the market for making LED bulbs with double the normal filament? If phillips wont do it some other company should. Then advertise as more reliable than other brands with 'high temps'
I think it's insane that you say "it is how it is" and no one responds. Are we in a program??
hrm... i wonder how feasible it would be to "clone" these lamps using off the shelf components (including regular dome LEDs) and using a larger sized bulb as case (to not have to minimize as heavily). not considering that it would involve making and fiddling with bits and pieces that will be live at some point :P
pretty feasible i would say, you can buy the filament leds now.
Open Notice to Any Manufacturer:
Make these for everyone. If you produce them with the same quality and engineering you could $€££ them for whatever price you need to and you would still $€££ millions of them.
Wouldn't be too difficult (at all) to modify the Chinese existing LED PSUs in this way. Probably will need a little experimentation on component values but would nevertheless be a very worthwhile project perhaps?
Hi Clive,
Totally off-topic. I'm looking to run mains electricity to my new shed. I was going to use the twin-and-earth that currently runs a faulty motion-sensitive lamp, rather than getting someone to install a new spur. What'd be a good jointing option between a twin-and-earth and an armoured cable I can bury next to my lawn?

If suggest running a dedicated cable. You can bypass red tape by bringing it into the house and plugging it into a socket for a 13A supply.
