576 Samsung LM301B diodes draw a total of 240W from the wall. Large aluminum heat sink keeps the diodes cool without the need for fans; saving power, reducing dust build-up and eliminating noise. The low profile design saves space in tight grow areas. Powered by a Meanwell HLG-240H-54B driver mounted to the back of the unit along with a dimmer to easily adjust your light. The unit is completely assembled with no wiring necessary, simply plug and play. Choose between 3000K, 4000K or 3000K with 660nm Deep Red Diodes, we recommend the 3000K if you plan to buy just one light for both vegetative and flowering stages of growth.
