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.
