This Powerplant grow light kit is great for growrooms where heat can be an issue. The Aerowing reflector has 6" spigots at either end for it to be connected inline into your ventilation and a glass panel seals the reflector, this allows all the heat produced from your lamp to be removed and lower your growroom temperatures. The Powerplant Daylite ballast is vented and finished in black to help reduce the heat more efficiently from the ballast. Rubber feet are fitted to prevent any vibration or noise being created from the ballast. A Powerplant Super HPS lamp is supplied with this light kit.
