A look at some super-cheap mini 10W LED floodlights.

You can now buy me cake and things to take apart at:-

Just for fun I ordered a couple of very cheap LED floodlights from China on ebay. They cost less than £3 ($4.80) and were rated at 10W.
As regular viewers of this channel know, this doesn’t always mean 10W power output. I’ve had others that had a 3W lamp power supply driving a 3×3 9-12V LED.
These ones were different…. They have the full 10W supply running the LEDs 9 chips in series at around 30V.

The cold white unit was cold white, the warm white was a nice golden warm white. Neither was earthed quite right, but easily fixable to you and me.

In other words… They’re surprising little lights. But does the size really have the ability to dissipate the ten watts of heat? I guess there’s only one way to find out…

Here’s the ebay listing I bought them from.

Note that sometimes the price gets put up when I link to a product and it is popular. It’s worth shopping around if it looks like they have hiked the price.
