I am planning on building a LED light based on this thread (https://www.rollitup.org/t/diy-led-grow-lights-with-cree-cxa3070-cobs-and-cpu-coolers.805681/). I have already started working on a arduino based watering system and figured I should hook the LED light up to the arduino. I am trying to find the best drivers for pwm dimming the lights with an arduino. I have used these before (http://www.rapidled.com/mean-well-ldd-1000hw-dimmable-driver/) to run strings of 3W LED's for a terrarium light and they were simple and work great but the best I could find in that line for this application would be (http://www.mouser.com/ProductDetail/Mean-Well/LDD-1500LW/?qs=sGAEpiMZZMt5PRBMPTWcaRgaVnaXJTVtr7GmcqdTR/kiEoXO42jViw==) which only goes up to 30v output. Can anyone suggest a better driver that can run off 5v pwm from an arduino for the CXA3700?
