Great for driving 1watt LEDs in series. Can drive up to 4-5 Red LEDs in an automobile application (or 3-4 White LEDs)
None really. Needed to remove the "MR16" posts, but no biggie. May provide FM radio interference, but see workaround below.
I'm using this in an automotive brake light (LED) application. Unlike another review here, I kept the bridge rectifier diodes, but proactively attached a 100nF (0.1uF) capacitor across the output (close to the LEDs) and have NO interference issues at the radio. This replaced a setup that used to have interference with the radio, so I know the pitfalls. I listened carefully to my radio on weak FM stations to confirm. (Note these are mounted in taillights, less than 9 inches from my car radio antenna.)
Perfect for driving 1watt LEDs
