MR16 3*1W 300~350mA Constant Current Regulated LED Driver (12~16V Input)

Pros: This is a really nice driver for high-power LEDs. I use it to drive Luxeon Endor Stars. It delivers 300mA to 350mA to the Endor Stars which are wired with three high-power LEDs in series. I run it off of my 12V car battery. Unlike resistors or voltage regulators it wastes very little power. It is very much like the Buck Puck drivers that cost $15. It's very simple to use it will run on DC (any polarity) or AC. The chip used in this drive is a PT4115.

Cons: The only con is that this driver has two big pins for input voltage. They probably fit some kind of light, but not mine.

Other: This driver will work with any set of LEDs which all have the same 300mA current requirement. Just put them in series andd hook em up. BUY IT

Pros: Well labeled, Wires solder well. Got exactly as pictured. Bought lot of 20 and all worked. Wire is on the flimsy side. about 1 inch in length.

Cons: The pins are slightly closed together. Most had to be separated a bit to fit in the mr16 sockets.

Other: Seems well built. Exactly as I expected. Will buy again when I get a chance to build more lights. BTW, i am using it for landscaping light hence the MR16 connection.
