Hi Supra, wanna learn to calculate a driver for led but cannot wrap my head around it, just bought the Ebay Cree XPE multis with 8 red + 2 blue but the 30w DC30-36V 1000mA driver the seller sent could be wrong? Cannot afford to mess up again, I know it´s a lot to ask but is there anyway I can calculate a correct driver for that 10x red/blue XPE´s in series? Love your work! Thanks, have a nice day and take care.
