Pure aluminum profile, Exclusive honeycomb cooling material Innovative heat and cold self-circulating system heatsink The air flows in through the holes on the side and out through the honeycomb of the profile, by this way, quickly heat conductivity,fast heat dissipation Efficient heat dissipation, reduce light decay, maintain perfect working of grow light Compared with other grow light radiators on the market, our heat and cold self-circulating radiator can effectively reduce the temperature less excess 15 degrees Celsius than others.  Keep the running temperature of grow light on optimum Reduce extra HVAC（heating, ventilation, air-conditioning, cool ） costs
