What;s the best driver for these LED's?

[eli@fijireefrock.com]

XM-L Cree should run at 3.3 forward V at a 3000MA
4 led X 3.3v= 13.2v should be safe for a driver between 12 and 14v with max of 3000 MA.

1st try to find a charger laying around the house that has similar output in DCV.if not check out meanwell and TRP website for drivers.

For my sump i am running 2 led 3w at 1400ma for a couple month now with no problem, the driver is an old cell phone charger i lost. my charger's spec output is 6.5dcv 1.4 Amp
