I just got a couple of these: "3 Watt LED Driver White Blue Green IR Input 3v~12v" from the EBAY store, but no data came with them.
I wonder if there is a data sheet for this product? At the least, I'd like to know what connections are what.
The back of the unit seems to be designed to connect to a battery's positive "tip" while the surrounding ring would fit against a machined aluminum tube in a typical AA cell flashlight. So that would seem to be the input side of things. But a different thread here shows some photos of a connected LED driver, and they appear to be feeding the input power to the other side of the board!
Maybe I'm missing something, but I can't find a data sheet for this device anywhere on this site. Thanks!
