These guys solved my issue, I was dubious about installing LEDs or CFLs, then this guys said "why not both?" And created this amazing product. It's so good that I used it in my hotels and my hotel. 11/10
Aren't they amazing, and so safe too! To think they output as much as an old 200W incandescant as well, it's just a miracle of technology. Would you like to buy any tin foil hats btw? They stop those 5G death beams that are everywhere now, maybe hand them out to some of the guests in your hotel and your hotels? ;-)
"Can adapt to China's actual situation"
Actual situation : voltage fluctuates from 86 to 265 volts?! ...... Got me dead💀😆
Schrödinger's death bulb.
@@KrotowX sorry, who's death bulb ?????🤔
@@brucepickess8097 Schrödinger's. Read about Schrödinger's cat ;) The same here - either bulb is alive or dead.
@@KrotowX bro.... Schrodinger's death "BULB"?!?! 😆😭🤣....
In my country it's always about 251 volts ⚡️ 💀☠️
You should do a collaboration with Big Clive on Chinglish writing on Chinese electronic products, it would be hilarious!!!! Great tear down as always DGW.
@Agustinus Reynaldi do you think Fool bridge rectifire ends as Great Scott said !! I don't think soo
Yesss😂😁😂😁😁😂😂😂😂😄😄😊😊😊
Oh my sides, reminds me of a glue I have that says hint of scent
totally. That would be so exciting... How exciting? I would squeak like a little girl...
on the hilarity of this exact subject (the Chinglish, not sounds I might make and how much they resemble those of a little girl): in the local convenience store near where I live, I once observed amongst the several random products that were often displayed along this one shelf, a silly toy truck, upon which were all these cheesy stickers no doubt translated from Chinglish. They said silly things like "big power" and "super this" and "mega that" odd and not quite right stuff like that... and this one sticker stated with a big exclamation point: "A kind of truck!" I laughed my ass off. I should have bought the thing just for that alone but they wanted like 25 bucks for it and I just couldn't.
Peace be upon you, sir.
Dodgy circuit, hilarious box and great circuit explanation. Enjoyed thoroughly haha
Maybe the label is made in the EU and the lamp in China 😁
Yes.
😂😂😂😂😂😂
I'd try this one on a variac to really see if it accepts "china power grid situation"
"China's actual stuation of power grid"
A calculator with no numbers on the keys, that's an interesting concept. Add's an element of surprise into math. Nice!
At first, I thought using the CFL glass tube was a clever way of reusing old stock of that twisty glass... then I realized that, well... I'm not sure it would work that way, not without modification to the glass. Right? Also, the LEDs would probably be getting fried with no airflow or way to cool properly.
What a weird lamp!
I believe that plastic tube was straight at begin of process. After aluminium strip with flexible led strip above it insertion into tube contraption was heated and flexed into right shape.
It is, probably not (just) the old stock, but the machinery used to make them, which is worth more (if it can be put to use).
@@Fridelain Indeed it may be the one of reasons too. Though particular bulb shape went out of trend a decade ago.
I think this is a regular CFL but modified the machinery to skip the spaying of the inside tube with phosphor coating.
Then just insert the LEDs and the PS.
@@piconano I also support this hypothesis
China is a very big country, and I think things are not as standardized there as in the rest of the world maybe.
My understanding is mainland china is mostly 220V 50Hz, and I'm not sure but I think they use both American-style and Australian-style outlets, though the Chinese ones are slightly different than the actual US or AU ones. I think ungrounded outlets are US-style while grounded outlets are Australian-style. I also get the impression that it's not uncommon to find dodgy "universal" outlets in hotels or offices, and also maybe some places have 120V.
But it gets more complicated if you start talking about the special areas like Hong Kong. Hong Kong is also 220V 50Hz I think, but they use type D and type G outlets as a former British colony.
Taiwan also uses 110V, and I think US style plugs. (Yes Taiwan is not under PRC control, not trying to start that debate :P)
Taiwan isn't 110v but 120v, I live there and you wont find 110v anywhere.
@@KahruSuomiPerkele ah wasn't trying to be specific. In the US people say 110 and 120 interchangeably when the voltage can actually be anywhere in that general range
Sure Taiwan prepared well to twhart mainland China soldier plan to boil tea in their own electric kettles.
these where popular in denmark too!! in my home we didnt change light bulbs from 2009 to 2017 (so basically all regular CFL until then) but my grandpa had bought some of these CFL looking LED bulbs and my uncle as well had them in the driveway street lamps around 2012 :)
I can't stop my laugh while reading lamp descriptions on packing box! LoL. Thanks for tearing down electronic with sense of humor. Not only giving knowledge but also entertaining!
Nice! Even in Australia where in theory are strict conformity laws we see such items. You could glue them 2 strips under a shelf and make a traditional isolated supply. I bought fluoro substitutes from very reputable supplies but the inverters still die shortly out of warranty. We live in a throw away world!
I actually like how these lamps look. I was tempted to buy one (with U shaped tubes) some years ago (the only time I saw them where I live), but the high price for a product that I knew was probably crap convinced me otherwise. I would like this same idea but whith LED filament even more!
in most of that Chinese junk, the wires act like a fuse
Mostly any components that are overrated act as a fuse after the emission of magic smoke.😏
Hahahaha, what a translation, incandescent "bulos" which in Spanish means hoax XDDD.
You need to make a few videos on computer DVD drives. They are a true goldmine of technology-brushless motors, brushed motors, magnets, lasers, nylon gears, stainless steel axles, PCB's with golden components like voltage regulators, motor drivers, memory chips cpu chips, headphone amp driver chips, indicator leds, potentiometers and more. I think you could trully make a 30 part series on reusing these machines of peak capitalist material abundance.
"Vyrobeno w Cine" && "MADE IN EU", hmmm... even a stupid label contradicts itself.
I'm not surprised that MCPCB is used, theoretically it should help with heat dissipation, but since the strip is enclosed in a plastic or glass helix, the hot air can only travel upwards into the sealed case where it can't really exchange heat with the environment.
Nice circuit design, but the unsoldered cap leg was definitely a bad thing. Looks like it was soldered by hand, at least the THT part, and a mistake happened.
Nice VFD calculator! Non-destructive teardown, please.
China is having a lot of power cuts lately in some cities, so the grid is more like 0v instead of 86v. :D
With the claimed efficiency, I wonder if it produces light output at 0v. That would be /very/ adaptable.
@@antibrevity At 0V the lamp produces high quality dark Ra=0 with 100% efficiency.
I imagine that the redundancies are from automatic translating where 2 Chinese items are simplified to a single English word or object (i.e. two types of street lamps). However, automatic translating doesn't produce typos so the writing was translated and then transferred by hand into the print files. Bizarre.
Yes, Chinese do have multiple words for hotels.
I currently live in asia and it's harder for them to know if redundency makes sense or not if they never spoke english.
As for the typos, it's probably a picture to text conversion, which would explain the missing spaces and the "dislexic" errors such as c instead of o etc... my guess on that one.
Luckily they at least learned how Latin characters look. Seen an "ingenious" sign for Russians where text in English was printed with Cyrillic characters.
@@KahruSuomiPerkele Well, the typos are for sure generated by an OCR software, so my guess is that you are right.
LEAVE THE CALCULATOR INTACT!! Thats a working relic of the past and they all eventually go bad. please keep it good!
That machine is a thing of beauty, a historical masterpiece!
aww, I've missed that level of comedic english on product packaging. now it seems like most chinese manufacturers have managed to hire someone competent to write what goes on the box, but this is a return to the glory days of 10 years ago when you were almost guaranteed this level of entertainment with every ebay purchase. the actual lamp too has that same flavour, super budget-cut, weird old-stock cfl housing and badly made buck board.
Just the engineering behind this and production cost they could've just made a simple but robust LED light
8:05 Well, it's very warm, the capacitor needs cool air on its legs! lol 😂😂Thanks DGW, another great video!! God bless you! 🙏
Aside from the power supply and box issues, the method of using LEDs on an aluminium strip seems quite an interesting construction
Seems good for heat disipation.
Tak koukám, že obě věci v pořádku dorazily, to je super :) Cena byla vskutku 59Kč, ale dva roky nazpět, co jsem ji koupil. Teď jsem už nekoukal, jestli to tam ještě mají a kolik za to chtějí :D
OMG! Quite a lot of grammar errors. What do you expect from a Chinese product, especially no-name?
A most enjoyable video both from the point of view of the printed text on the box, and the circuit analysis.
very minor detail, but if anyone was wondering, the circle instead of a . is because there is . in chinese, they use the circle
Add a fusible resistor and remove one current sensing resistor to reduce the current and it will last for years.
1:54 Was that lamp made for export since its 240V rated instead of 230V?
I had one of these since 2012 and it lasted until last year, it finally died because of corrosion, the glass tube is all crusty because it burns the dust and bugs that step on it
Thanks for my daily laugh, especially when you 'got stuck in' with the screwdriver.
I kind of like the look of this lamp - definitely not seen at my shops in Australia
although I would be tempted to replace the regulator.
0:35 The small circle is the full stop that's used in the Chinese writing system.
This thing can be made decent just by adding a fuse and stuff like that, and redoing the soldering. But of course you need to be able to open it without destroying the package!
Whoa I just clicked on this video and there were 555 likes. Nice
8:03 R U KIDDING ME GUYS?!?!
1:45 meabe they use Samsung LM301H high end SMD leds in package 3825? just joke 😂
The lamp is most efficient when you don't buy it.
Nice Video :). Would love to see the calculator in another video! I have one with those vfd tubes too (But it's a bit smaller).
Would be nice to restore key labels on that thing.
I bet they founded a special industrial zone in China and called it EU…
Label made in EU. 🙃
Já jsem pro nakouknutí dovniř té T801, klidně i překreslení schématu.
Very interesting 😂😂😂😂🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
It would have been nice to do measurements before soldering capacitor to see how it impact the output.
Yeah, I hoped we'd see that on the 'scope.
I too expected another measurement with capacitor disconnected. It should cause awful light pulsations. Not exactly visible by naked eye, but very tiresome during a hour.
Comical Chinglish! :D
You are more funny than the package
The cat is waiting for a bath in the basin.
I have the same, but with the standard CFL design. I've bought it for 3€ in Normandy, as the factories won't be able to sell it because of the design. So they sell it cheap! Maybe they thought people would enjoy this kind of light bulb, and still continue producing the CFL design at the same time? I dunno XD
China's power grid is somewhat unreliable so there is fluctuation of voltage and frequency but the nominal voltage is 220V 50Hz throughout the country. (Unlike Japan where the eastern half the country uses 50Hz and the western half uses 60Hz)
Hmm ching-lish, So much bullshit!.
Well it works but how long for lol.
Even your quality control cat thinks it's crappy :-D
bloody helll. super dodgyyyyyy
I would like to see a video of how you can make the schematics. Very good channel
Bro I think is great you to build EST Analog Meter & LCR Analog Meter with programing chip & sircuit design 👍🏻🙏🏻✨💖
Small circle is the Chinese dot。
China domestic power is 3Y220. Line to Line is 380V, Line to Neutral is 220V.
At least it has holes in the housing for airflow over the driver, also the leds are seperated from the driver.
if the components are of reasonable quality it should last a long time
I think that label is perfectly OK. You didn't know, that EU is part of a Great China?
the bang will be the brightest moment
i have a similar lamp, bought on purpose for 1€, it has the previous version of the CFL tube (the multiple U shaped one), still glass, never used it, i keep it as a collectible LOL i know it sucks big time, also the LEDs are eye piercing
Yes, i'm calculating on you to open that calculator! Thanks for the presentation of this indispensable CFL-style LED lamp, oh the ideas that pop up in some peoples heads!
Now I want to go buy one
cperating
😂😂😂😂😂😂😂😂😂😂
Ordingaryly I don't leave a comment , but it is strange that in 2022 that somebody at the companies grandkids could not translate it properly for them 😁
The fact that watts are unit for power its widely used for different types of applications that marketing will utilise confusing ambiguity to catch consumers attention but just remember an led light bulb W rating is its power consumption unlike a laser pointer that doesnt advertise consumption that is rating for output :)
that does not look too dodgy.
unless the dodginess comes from the waveform kicked back into the electrical system.
in theory if you have many of the bulbs connected the harmonic distortions could build up and burn your house due to electrical induction distortions and such.
The heat in that tube must be baking. Those strios look like the 40vdc in my shop that I had to repair - they melted the masking tape I was using to temporarily hold down an end.
Teach China English first 😂😂
Thanks for this -= you have totally convinced me. I don't want any.
- This is not the right way, but we like it anyway... Now you sound like UK DJ Solarstone :D
The demonstration is much more funny!! This made my day!!! 😍😝
0:35 The small circle is common in many Asian languages, normally U+3002, 。 or。。
"Made in Eeeyooooou?"
I’d buy one of those just so I can laugh at the false claims and see how bad it really is
Who is from Czech knows that the texts on the labels are interesting. :)
Those weird typos must be OCR translation
So it's only 10W (rounded) power and also not 360° beam...
They probably had a warehouse full of unsold CFL bulbs.
Please make a video how do you make circuit diagram of any circuit boards
16-18w led equals 100w tungsten to human eyes
There's a datasheet available for the CL1502 but it's only available in Chinese and the manufacturer only does commerce in Chinese...
The text was Chinese and they used an OCR tool to convert the translation into a text format on a fax or low quality printed document. Loads of stupid claims though make it look like pure incompetence in the marketing department, who just happens to be the same person who mops the floors, because he claims to have a cousin who speaks english, but he didn't even have that!
In fairness to them, they probably have a mountain of parts intended for other applications, reusing what they have lying about in as an efficient way as possible. I don't think sticking the LED strip down the glass so bad, provided it wasn't push so hard. Do a bigClive mod to lower the output of the buck regulator and maybe the lamp will last a fair while. Getting to it and reassembling the using might be an issue though.
I found Osram CFLs died from this kind of poor soldering.
Its watt rating of 12 is input consumption not the lumens output....
I was surprised by the output capacitor. It's only 3.3uF and rated for 250v even though it only sees 35v. 15uF 50v would make more sense. They probably copied the value from high voltage LED string drivers.
This buck regulator board is very common in India for replacement for original buck regulator in 9 to 12 LED bulbs for which It costed only ₹20 per piece few months back. Drawback is that output voltage is little higher than required.
maybe leds made in china but assmbled in czech??
The best part is reading Chinglish :D
The aluminium plate on LEDS is on the heatsinkig?
6:19🇨🇳製劣質品認定 沒有保險絲與突波吸收器「壓敏電阻」

8:00呃呃虛焊
Incandescent bulos,Made in EU 🤔🤔🤔
I love your videos about crap devices 😉
Is the tube of the 'CFL' plastic or glass?
Pleas finish the DD metal detector and test out of the lab
Needs to recheck bulos after CAP resoldering and 230VAC mains. Funny bulos anywayos.
Maybe the label was made in the EU xD
Those EXACT LED lamp, are available in my country for around 3 years now, available in store called 1$ store.
So when you buy something from there, do not expect for the best technology quality available.
I still got 2 plugged in the ceiling at my balcon. We do not turn it on for a long period, just when someone need something there during night, and so on, that is why , they are still alive.
In salon or kitchen, same model lasted for 1 month or 2, then there build in LED started to burn 1 after another... very bad cooling...
I personally like the LED E14 lamps in the style of the first old Edison carbon ribbon lamps with a "designed" radiation temperature of 1800 K. The flexible substrate was really a technological challenge in the development of this light emitters. But I like them because of their candle like radiation temperature even if you sacrifice a good percentage of COP.
The closest Chinese bazaar to my house prints its own stickers with custom barcodes, a fake CE mark and "Made in China" so everything becomes instantly CE approved and Chinese, the funny thing is that a few categories of products are actually made in Spain or other EU countries and comply with all EU regulations, they do not import certain products from China simply because their customs tariffs/taxes or something similar are very high to avoid unfair competition with local companies.
I love your videos! Thanks for explaining and showing electronics also telling its safety it really helps! Also can I have a shoutout plz/please? I'm your 9th commenter!
Wow, that's not a very good LED... I was half expecting you to end with "so the conclusion is... super dodgy!" like you do with the USB phone chargers.
Why would they re-use a housing designed for CFL light bulb...
It's not super dodgy. Actually just the fuse is missing and the soldering is bad, but otherwise I can't see anything wrong with the design itself.
@@gabiold Interference filters also missing.
I need to admit, in Comparison to what kind of dodgy products we saw here, this one is not that bad. It Actually Impresses me when after turning on, it didn't flickered in camera. But the package is a huge misunderstanding...
👍
