I just have to say that since I left the U.S. Navy after the first gulf war, I really lost sense of my electronic training and I regretfully didn't bother keeping up because after the wall fell down, there wasn't much need for my kind, I just became an electrician. Thank you for re-awakening my passion. LED's, Who knew?
The 'bootstrap winding' that power the switchmode controller once it's started up can also be used to detect the secondary voltage simply by turns ratio.
Wow, after years of seeing the generic Chinese cob lights of death, I was not expecting to see some genuine decent engineering in this one. It certainly looks light-years ahead of the usual ebay ones.
I love listening to you describe all this stuff cuz I haven't got a clue what you're talking about but I think you would make an awesome addition to the engineering section on the star ship Enterprise. :) I'm sure it doesn't sound nearly as impressive for those trained in it, but it sounds good to me.

+Kukielka --> Well he does say in the beginning that he was an apprentice. He says he was an "electrician's" apprentice but he just doesn't want to mention he was a Jedi apprentice that later turned to the LED Side.
Great advice regarding a trade for life. I did the same thing in the commercial printing industry. Kind of sucks, the printing profession vanished over the years.
Very nice lightbulb. I wasn't expecting a corncob to be this high quality. Why is there a grille for the fan, instead of just an open circle for more airflow?
Not certain, but from perspective it looks like the power supply is a switched mode supply that provides good mains isolation. The 2 toroid coils are a strong indication along with the transistors on massive heat sinks. Not a conclusive analysis, but check the mains isolation that's the important part. I appreciate your videos. I've always been curious about the tech that was a breakthrough in LED efficiency, somewhere between 15 & 20 years ago. One video I saw showed the semiconductor layers, so not my question is answered. A far more elaborate semiconductor than were their simple bipolar LED ancestors.
I believe these are spray booth lights not cheap pieces of kit. I have some 100w ones in for repair. They have a 12v fan and the pcb seams to be the same arrangement with more parts, like temperature sensing etc.. still no feed back tho. There designed for an open fixture due to heat. I'll try fill in the gaps as i progress, because it definitely seems like a repair is feasible due to there high cost.
You might want to add an annotation at 1:40 to correct that 66, which should have been 60. I notice I'm not the first to mention the error and I see you are aware of it, but an annotation would let people know who otherwise might run away from the "evil number" if they're able to do the math. LOL! I laugh, because most of the "numerologists" I've met are terrible with math, and will probably just be confused by the fact that this thing ended up with a 660, a 66, and a 60, and will most likely just assume that all adds up to evil anyway, but maybe not run away since they can't be sure. Those that actually can do the math, will likely just run away. Especially if they notice that the total number of circuit boards with LEDs on them adds up to 13. :)
I have used COB Lamps similar to this for over a year now in a commercial outlet at high level, originally they were running 200W SON lamps in the fittings but I have now swapped them over to these 40W LED COB lamps and the feedback from the customer has been great. They're not cheap at over 60 quid a lamp but for me getting access to the fittings and not having any maintenance issues with them is a no brainer + the added cost savings on their electricity bill have more than paid for them now too. These are the ones I use www.ledecolights.com/products/led360-son-replacement/e40/goodlight-6w-g360-led-son-replacement-lamp-e27-daylight-541
Well... finally some LED that is worth!! If this great light piece of enginering lasts long enough (with this quality seems that it will), I could say that's the only LED light that is worth of investment. Its light wouldn't decay with a short period of time as basically it doesn't produce heat and have a great energy efficiency as operates near to the maximum efficiency point of those devices. Altogether considering this excelent power source gives us the (maybe) only light that has a cost benefit far superior to CFL that's worth the price (I've checked 56 Euros).
I spent the whole time thinking about how one could arrange red, blue, and near-red LEDs in that configuration for a nice LED replacement for the big high-pressure sodium lamps I use in the greenhouse. I'm afraid however the high humidity would be the death of that nice driver board, and any attempts at vapor-barrier housing would probably ruin all the cooling built into it. I suppose maybe it would have to be a specialty unit with cooling integrated into the vapor barrier housing. Maybe this layout isnt well suited then, you'd want it to be split in half with the back side an big finned aluminum heatsink and the front a glass vapor-barrier cover or something...
That looks like 2 voltage regulators, not transistors. With bridge rectifier and a transformer it looks like it's AC to DC power supply built on the inside.
Nice light, I too wanted to see how bright it is in perhaps an outdoor setting. Is it 40w or Chinese 40w? Nice review for the tech, not so good for people considering to purchase.
Job security so long as you are not injured and physically capable of doing the work. Best work on a backup for the day when you can only sit at a desk.
You should invite me over to rummage through your odds-n-ends bins.. i'm just getting going with learning electronics, and i could use a decent amount of 'random' things to test / play / learn with :D
I have a bunch of 18 watt corn bulb that went out I want to know if I can send you one so you can break it down and show me what is going wrong thank you
Gonna be a bit cheeky here and obviously 4 years late but still, mine is bigger than yours Clive :) Now putting jokes aside, here's a 100W version I found when I was doing a job replacing the lighting in a clay brick factory in Austria. www.dropbox.com/sh/97vwpzdg2tgvhgx/AAAk83k1KZVMHZTDsfNBaqlFa?dl=0 It has 12 strips of 112 LEDs and another 112 LEDs on the top disk so altogether 1456 LEDs. Each strip and the top disk have 14 sets of 8 parallel LEDs. It comes with an E40 type screw plug and it also has 2 12V fans. One fan is at the base where the wires from the PSU are attached and the other is at the middle of the stack and they are configured so that the air flows from the socket to the tip.
You thunk? 20 years ago I was repairing PFC equipment in my Low voltage switch-room. Ideally power factor should have a value of 1 (power factor=true power/apparent power) when capacitive and inductive loads are balanced, however in most lighting and machinery, the load tends to be inductive, so you add capacitors to try to get the correction. Power Utility companies will fine businesses that run too inductive a load on their supply, and that's why we try to do something about it. Money.
I wish I could send my led tv to you to figure out.plugged in it reacts and messes with my radio clarity.not even turned on so I am guessing it is the remote controll circuit that turns on and off the tv that is the offending electronics. thinking of putting a seperate inline switch on the tv cable so I dont have to keep unplugging it.I also like your test mains connector.the box you open and lift the tabs then insert wires and then push the tabs down and close the box and its on.what is it and where can I get one.
+Jigar Thaker It's a class Y capacitor used to reduce electrical interference by giving a short return path for current capacitively coupled between the primary and secondary windings.
I remember this video and you talking about the apprenticeships and I commented on my old Channel That's now band however I realized something. You know who makes even more money than electrician? That would be a police officer because a police officer in California usually on average makes around 200,000 to 300,000 a year. electricians make nowhere near that amount of money but you know what at least you still have a soul after your apprenticeship something that you don't have once you become a police officer.
I had one of these on a pole light lasted about one year company replace it with a new one. Now the replacement is not working. The supplier calms the air is to dusty and getting dirty inside. Very poor design if dirt get inside and it stops to work.Changed it for complete sealed unit.
If you want to learn about the lamp, watch the video. *_However_*, for those of you that just want him to turn it on (which he doesn't in this video), see his other video of it here: ruclips.net/video/j7Dq2myAN7Y/видео.html
What brand of bulb is that? Does it produce a lot of heat? Where is it available ? Is it safe ? And last question, what color is it ? ( cool white or warm white) Thank you.
The pen I normally use on paper in these videos is a Pilot V sign pen. It uses liquid ink. If you search my videos for "pen" you'll find the one where I refill it with printer ink.
And he never switched it on. No cake for you!
nooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
i have learnt one thing by reading comments . ppl are more interested in finding mistakes then learning something new.
+Ashish Bhatt depends on how you look at situations, like this one, using his math i learned how to not get 660
I always pick up a few things when I watch these videos,it just goes to show you never stop learning.
I just have to say that since I left the U.S. Navy after the first gulf war, I really lost sense of my electronic training and I regretfully didn't bother keeping up because after the wall fell down, there wasn't much need for my kind, I just became an electrician.

All that time wasted waiting for you to switch it on.
+ajuk1 See the link to a light output test in the description.
But in all that time, there was plenty of things to learn :)
good way to milk views
I can't believe it's exposed to the air and not enclosed within a diffuser cover.
These bulbs typically go in tower lights or wall packs where they are safe from water and have the diffuser there.
Wow, after years of seeing the generic Chinese cob lights of death, I was not expecting to see some genuine decent engineering in this one. It certainly looks light-years ahead of the usual ebay ones.
arcadeuk "light-years" heh, I see what you did there ;)
Probably many light dollars ahead of the usual ones too.
12x50+66 isn't 660 it's 666
+Andrew Barry True, but it should be 12*50+60=660.
+Andrew Barry The light of the beast. Eco-friendly!
6 more LEDS and you could summon lucifer .... he'd dig your beard for sure
lol
There are 666 leds (12x50+66=666) not 660
Why do i find this so interesting? I've been watching so many of your videos now! Love them!
Holy crap...a REAL power supply
very impressive good to see decent electronics ain't dead.
I love listening to you describe all this stuff cuz I haven't got a clue what you're talking about but I think you would make an awesome addition to the engineering section on the star ship Enterprise. :) I'm sure it doesn't sound nearly as impressive for those trained in it, but it sounds good to me.
I’d definitely rather listen to Clive than either Scotty or LaForge.
Great video. Haven't seem those before on ebay.
RODALCO2007 I think these might be sold on ebay as high bay LED lamps.

Yes, but you got transferable skills in the process.
Wonderful and educational video! I'm an EE and love your videos.
This is a good piece of electronics in this lamp .. what its model and manufacturer?
What is the spark gap for?
Please show it.
Amazing the amount of electronics in this. Discouraging.

I am surprised this didn't have a fan.. most lamps like this do.
Oh nice they actually run the leds at 20mA
4200 lm ? nice. now... lets count the photons next.

13 mins I watched this to see how bright it was. I'll never get those 13 mins back.
power factor chip regulates INPUT POWER. it also regulates the output voltage. some outputs can be isolated or not. so 40 watts can be regulated
Great vid would have liked to see it on
(12 * 50) + 66 = 666, not 660.
Of those 66 only 60 are connected. The other 6 are decoration it seems so no real use in counting those
I could only count 60 on the top
Ah.. didn't read your background before I commented. I stopped at 9 minutes in when I wrote the msg below.

Give it some power!
That ventilation hole inside looks like a place for a fan tho.
There are 666 LEDs! This is a beast!
bigclive. sofa king funny,,, the "no cake for you" comment and the math test,,,, drive them crazy
There are plenty 24V fans that run perfect on 30V or even 34V. Tried it myself
not as bright as I had expected. Would the output be roughly equivalent to 4 60W incandescent lightbulbs.
wow exactly 70.000 subscribers; -)
I got some think like this 10 + years ago, it was equivalate to a 150w bulb, it lasted 3 months, then blow up, it got to hot,
i wanted to see the light running

Come on! Couldn't they have put in 6 more LEDs?

Is it 40w or Chinese 40w? Nice review for the tech, not so good for people considering to purchase.
Hi Clive were would I get one from and would they be any better than a 300w cfl grow light
Use the force Clive, Welcome to the dark side. We can use your knowledge of light. 👍🏻😂
6:38 "...we have to use the "force"..." 👍 good one. But why haven't you turned it on???
Is this the quality corn cob LED light bulb I've been looking for? What about light performance, power consumption and color range?
Have you shown a capacitive dropper powered AC configuration of a led device , IE no DC at LEDS ?
Need to bolt 6 more of the things on somewhere.
Good lamp, use good components, using rubycon caps.
They have this style of bulb going up to 100w.

One fan is at the base where the wires from the PSU are attached and the other is at the middle of the stack and they are configured so that the air flows from the socket to the tip.
Looking at the power supply with a 'scope, we would know what is filtered and what is not.
why is ''power factor'' important? 20 years ago no one mentioned it.....

really though would this work in a normal american lamp/ceiling fan?
note to china this is how its done
PS great Clive ( the techno bear )
wow, my handwriting is almost the exact same as clives

Which type and brand of camera do you use for your videos? Image is so clear even when you zoomed in inside the light bulb.
Goku Nimbus It's an iPad 2 with good illumination.
Damn.
Sir, at 9.00 you mentioned the name of blue capacitor..I didn't get it ..Whats the type of capacitor?
+Jigar Thaker It's a class Y capacitor used to reduce electrical interference by giving a short return path for current capacitively coupled between the primary and secondary windings.

all that and you didn't turn it on?
It just swamps the camera when it's pointing at it. the light output is quite bright and very even around the room.
bigclivedotcom come on clive you've gotta do a video of the light on and what is it equivalent to :D
bigclivedotcom
i've just never seen one like that
i have no idea what it even does
I agree too
what kind of PF did this unit get?
Why did you not switch it on???
where did you get your carousel of screw driver bits from?
Poundland, like the black handled ones he uses.
I had one of these on a pole light lasted about one year company replace it with a new one. Now the replacement is not working. The supplier calms the air is to dusty and getting dirty inside. Very poor design if dirt get inside and it stops to work.Changed it for complete sealed unit.
how much did that sell for?
I was always told to never touch the capacitors lest I get zapped. Is that not true here and why?
It's wise, but if the circuit has been disconnected from the supply for a while and has discharge resistors then it's normally safe.
such luxury :o
Wanted see it light

Can you make a video where you turn it on in a dark room?
+Taylor Downs There's a link to the demo video of the lamp in the description.
What brand of bulb is that? Does it produce a lot of heat? Where is it available ? Is it safe ? And last question, what color is it ? ( cool white or warm white) Thank you.
Brian Mc Donnell it would be a cool white. (yellow leds usually cool or natural white, orangeish leds usually a warm white)
Why not switch it on? 12 minutes of my life I'll never get back.
