Inside a deformable LED robot lamp.

I had a few requests to get one of these and take it to bits, so here it is.
It's a fairly high power 60W (50W) light with three panels that can be aimed independently to light specific areas of a space. It's described as being an industrial high-bay style lamp but has a lot of other uses.
The temperatures I measured were lower than expected. The back of the heatsink remained at a touchable temperature at around 45C at the centre and quickly diffusing the heat through the generous and stylish heatsink. Of more concern was the circuitry temperature with the back of the PCB measuring 80C when I removed the cover and then dropping a bit when there was airflow.
It suggests that an extra strategically drilled hole or two in the top could allow better airflow through the driver section. The large foam pad that holds the PCB in place also presses right against the back of one of the drivers, including what could be a track area intended to dissipate heat - so it may accelerate the failure of the middle driver.

You can get these lights from banggood and on eBay. Here's a generic eBay search link:-

Not sure I'd recommend the plastic version for heat dissipation reasons.
Target price is around $25 shipped. Make sure you get the right voltage version if there are options. You may also get colour temperature options.

I've had a few reports of people getting shocks from metal housings on LED lamps and tubes. There's very little clearance and no grounding in many of these devices so it's inevitable that some will become live either through manufacturing flaws, shipping damage or failure. I always recommend that if you are installing new lamps with the power on, you make sure there is no easy current path to ground through your body. If in doubt, turn the power off or wear a glove on the hand you are using to put lamps in.

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