Cree COB CMA3090 led 48v 3600ma 3500k 12,000 lumen 175W Genuine.

Listing is only for 1 LED

Maximum output is 175 watts!!! These need to be heavily heatsink .. water cooled or copper fin heatsink with a fan. Think gaming quality CPU coolers. Don't look directly into these, it's more painful to look at then the sun.
