I put two 10 watt versions on the Tormach a few months back and they seemed to work OK. I ordered 2 more for the lathe and those didnt perform well, wound up ordering new drivers and chips from another source and now after being repaired seem to work OK.

I recently ordered a 50 watt version and its measured wattage was only 15 watts approximately.

I am wondering if others have had similar experiences with the Chinese LED lights, or know of a source to get whats advertised?

I did connect a driver that is known 50 watts, the heatsink on the chip got so hot one could fry eggs on it after about 15 minutes! The light output is good though, but it wont last long running that hot, I guess I could add a muffin fan.

I wonder if any of you guys have had any experiences with these lights?

thanks
