-It delivers very reliable current, ~620ma by my measurement. -It can easily power 2 leds in series off of a 12v battery. This is an excellent feature. -Easy to set up -Driver stays cool
It has a bridge rectifying diode set up so that it can accept ac or dc. Not a real con, but you can bypass the diodes if you check the polarity and save a little efficiency when running off of DC.
I used these drivers to power some 12v lamps with two 3w LEDs inside each. I got to test it during a blackout and there was so much light in my living room it was like our house was the only one on the street with a well lit living space.
This is a very useful product. Perfect for what I needed it for. If you want to power 1 to 2 3w LEDs off of 12v, this is the driver you want.
