GU10 300mA 3W Power Constant Current Source LED Driver (220V)

Pros: Good price. It works very well with 3x1W LED's, barely warm to the touch. Voltage across led's was 3.1, 3.0, 3.2 at a constant current of 300 mA. Driver build with AP3706 IC which can provide constant voltage or constant current regulation.

Cons: Some SMD parts were not well centered on corresponding pads, but soldering is good and it works without any modifications.

Other: Good and inexpensive LED driver, also small for any LED diy. If you need a small, inexpensive, good driver BUY it. I will buy some more soon.

Pros: Nice, small and easy to use LED driver. Bought one for testing purposes- for test driving 5W 10V LED diode. While testing, it didn't produce to much heat.

Cons: For now hardly any. Maybe the clearance between high voltage side conections is a bit low.

Other: Useful driver for that price. I will buy them more.

Pros: extremely cheap, when u notice your led bulbs are not working just replace the drivers ,direct replacement for the e27 leds that im using and its small enough to fit in with ease, and much cheaper in the long run then using energy saving bulbs

Cons: make sure you have enough ventilation for your led bulbs , if your led bulbs produce too much heat it will destroy your driver, so far i had to replace many drivers for my led that are concealed in the water proof casing for outdoor usage but i have not replace any indoor leds so i suspect its the heat that causes the drivers lifespan to be extremely short

Other: cheap and easy to replace
