I'm planning on buying a dozen 3 watt luxeon leds and found a seller which also offered me a led driver.
I asked him for a spec sheet but all he could give me was this information:He also sent me a picture:  Do you think I should buy it or should I only buy the leds?Voltage: 12v
Current: 330mA - 700mA.
It can work with 1x 3w leds or 3 x 1w leds.
The leds can be connected in parallel.
I was also looking for a driver which allows me to connect many leds (more than 3 or 5). Which would you suggest?
Thanks for reading and replying!!
