You can get some very resonably priced drivers online. Try these two sites that I use.


Dealextreme is in Hong Kong and shipping is always free; but, it may take several weeks to get your goods. I have ordered from them many times and have always got my order though so I think they are great.
SatisLED has good pricing but you have to pay for shipping. I have not ordered from them yet as I just recently discovered them but they have great prices also.

funny, the first result for 'power led driver' is https://www.instructables.com/id/Circuits-for-using-High-Power-LED-s/

use that.

You need an LED driver.
What spec's for this thing?
