I thought I'd throw in an old-skool lamp video. I used to make quite a lot of videos about random LED lamps, but the electronics seem to have standardised so much now that the mechanical construction is the most interesting bit. They use a lot of nicely machined alloy components. They also seem to have moved on from just doubling the rated power for sales purposes to tripling it.
The COB LED in the larger lamp is based on six half watt emitters wired as three sets of parallel pairs wired in series.
I've taken one of the small swivel lights apart before, but this one seemed to clamp the LED down better. It uses a very standard 1-3W driver that can put out between 2 to 12V at a current limit of 300mA. This allows it to drive just one LED or up to three in series (probably four if using red or yellow LEDs.)
Here's a search link to the littler swivel 1W LED lights:-

And a starter link for the slightly harder to find large COB style:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

Some chinese companies sell 6, 12 and 24V GU10 lamps and even 230V mr16 lamps. Bangs will be more common if users dont check voltage ratings.
Yea I've bought those cob spotlights for a while and have noticed the 3x power rating, for at least 2 years now they've been selling the same type of designs, but at least they don't flicker like the cheap ebay filament bulbs, those are disappointing.
Hey BigCliveDotCom… Where would one go about figuring out electronics and understanding the circuitry as you do? What would be a good first step, and what is the actual sciencey term, electronics engineering?
@Clive. How safe actually are these led lights from China? Is there any safety build in these chipboards to prevent them from overheating, melting of setting fire?
It would be cast and machined from what I see..
Yes…those things tend to be a nightmare to anything 30mhz and below. =(
No audio for me. Anyone else having issues?
FULL BRIDGE RECTIFIER!!!
Another obsolete power supply chip.
I watch your deconstruction of cute little power supplies with impressively low parts count and all I can think of is how we are destroying any possibility of using the RF spectrum for low power distance communications, as we were doing since we got rid of that old spark gap stuff. For awhile there <500khz was abuzz with interesting experiments and possibilities. Now it is just abuzz. Half the LED traffic lights (somehow exempt) shamelessly roar straight up thru and past the FM and Aircraft bands also.
I hope you report these sellers for false advertising…
Maybe you can take a look at industrial connectors from ali?
Just search for "HAOGNCN" on aliexpress. These connectors are very cheap, they seem to be a ripoff of german Harting/ Wieland/ Amphenol connectors.
Think I found my next favourite youtuber
Disappointed at the lack of notepad and pen in this video 😂
Imagine that: a chinese package that lies about it's contents – not only in wattage, but appearance as well.
