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

"Can adapt to China's actual situation" Actual situation : voltage fluctuates from 86 to 265 volts?! ...... Got me dead💀😆

A calculator with no numbers on the keys, that's an interesting concept. Add's an element of surprise into math. Nice!

Dodgy circuit, hilarious box and great circuit explanation. Enjoyed thoroughly haha

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.

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!

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 :)

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!

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!

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!

A most enjoyable video both from the point of view of the printed text on the box, and the circuit analysis.

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.

I spent the last week binge watching your videos. Just wanted to say thanks for the great, varied and interesting content.

8:05 Well, it's very warm, the capacitor needs cool air on its legs! lol 😂😂Thanks DGW, another great video!! God bless you! 🙏

The cat is waiting for a bath in the basin.

Maybe the label is made in the EU and the lamp in China 😁

Aside from the power supply and box issues, the method of using LEDs on an aluminium strip seems quite an interesting construction

Please never stop making videos! You are great!

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.

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!

The demonstration is much more funny!! This made my day!!! 😍😝

I'd try this one on a variac to really see if it accepts "china power grid situation"

Another great video, thanks for the tip about the extra bit of winding on the transformer

Hilarious spelling on the box and a dodgy circuit wow! Great video i love these dodgy products and seeing how they have been made to be as cheap as possible

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.

I think you'd be the best quality control, leader. Since you always dive into circuit boards and take them apart, it is by far the best videos from you.

I like it, mainly for the size and simplicity. It has enough surface area to keep the LEDs from early failure and is priced cheap enough that one can almost forgive the flaws.

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

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!

You are more funny than the package

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.

- This is not the right way, but we like it anyway... Now you sound like UK DJ Solarstone :D

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)

very minor detail, but if anyone was wondering, the circle instead of a . is because there is . in chinese, they use the circle

Great channel.....many thanks!

8:03 R U KIDDING ME GUYS?!?!

Now I want to go buy one

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).

I love your calculator!!

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!

What a genius way to stuff led strips into an CFL housing! If leds' temperature does not exceed specifications.

I would like to see a video of how you can make the schematics. Very good channel

Add a fusible resistor and remove one current sensing resistor to reduce the current and it will last for years.

Just the engineering behind this and production cost they could've just made a simple but robust LED light

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.

Cute content of dodgy product 🤗🤗🤗🤗

"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

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

The small circle is what is used as a period (full stop) when using a Chinese/Japanese character set. The reason being that the solid dot is used to indicate a short stop between syllables in Japanese, as for Chinese I don't know as I can't read it well.

I love your videos about crap devices 😉

in most of that Chinese junk, the wires act like a fuse

They probably had a warehouse full of unsold CFL bulbs.

Thanks for this -= you have totally convinced me. I don't want any.

Would definitely like to see inside the calculator!

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.

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.

0:35 The small circle is the full stop that's used in the Chinese writing system.

The aluminium plate on LEDS is on the heatsinkig?

Please make a video how do you make circuit diagram of any circuit boards

There's a datasheet available for the CL1502 but it's only available in Chinese and the manufacturer only does commerce in Chinese...

bloody helll. super dodgyyyyyy

Is the tube of the 'CFL' plastic or glass?

Já jsem pro nakouknutí dovniř té T801, klidně i překreslení schématu.

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...

Yes you should open it :)

It would have been nice to do measurements before soldering capacitor to see how it impact the output.

Who is from Czech knows that the texts on the labels are interesting. :)

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

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 :)

Hahahaha, what a translation, incandescent "bulos" which in Spanish means hoax XDDD.

Needs to recheck bulos after CAP resoldering and 230VAC mains. Funny bulos anywayos.

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

1:54 Was that lamp made for export since its 240V rated instead of 230V?

Looks like some basement diy.

I wonder if the plastic is properly fire retardant or as dodgy as the rest and would self-sustain if it gets going...

The best part is reading Chinglish :D

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

Dva vodiče připojené k převodníku, možná je to pojistka?

What is the conclusion🤣🤣

12:02 why not using the square root button? 😁

Whoa I just clicked on this video and there were 555 likes. Nice

"Made in Eeeyooooou?"

Shenzhen engineering at its finest

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.

Funny box

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!

1:45 meabe they use Samsung LM301H high end SMD leds in package 3825? just joke 😂

Small circle is the Chinese dot。 China domestic power is 3Y220. Line to Line is 380V, Line to Neutral is 220V.

I have one of those.

Top good!.

0:35 The small circle is common in many Asian languages, normally U+3002, &#12290 or&#x3002。

Comical Chinglish! :D

I have those led drivers ...they are super worst ...even in 12v 500ma they are getting melting hot

I sent to your email my version of 2 displays clock as i promised.

Bro I think is great you to build EST Analog Meter & LCR Analog Meter with programing chip & sircuit design 👍🏻🙏🏻✨💖

Very interesting 😂😂😂😂🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣

So it's only 10W (rounded) power and also not 360° beam...

Those weird typos must be OCR translation

Sir im new subs
