Ok, so I buy one of these led driver modules off of ebay, made in china -- they work great and will drive up to FOUR 1W power led's in series at 350ma.
The transformer in this thing is really small, maybe a half inch square. It has a 120v input and who knows what out.
Something I think I need to bone up on are DC to DC converters because this is where the magic lies, correct?
So, if this little transformer can put out 35ma, with a 1 to 10 conversion, I have my 350ma?
The transformer doesn't even get warm.
