LED puck light conversion
I have seen many posts on this subject but very few posters list a source for the bulbs. I was told that there are some Chinese sellers on ebay with a quality product. Apparently if you buy in bulk t...

thermal management seems to be the lowest priority for the average Chinese engineer. Pack as many led onto as little pcb as possible, claim some ridiculous performance numbers.
There is nothing ridiculous about performance of LED that I bought (link in my post on the 1st page). It draws 5 times less current, producing visibly same brightness as the old incandescent. This is what most sources say where it should be. Temperature I didn't measure but surely less than 200F, more like 100F. No RF interference either.
Consider that LED is inherently 2 times more efficient than incandescent when you need a focused light, like in RV dome lights where you want it shining downwards. In LED all the light goes downwards where you need it. So, even a LED made rather poorly, with a lot of heat losses, and only 1.5 times more lumens per watt than incandescent, it would still produce 3 times more lumens per watt in the desired direction.
