The Nanolux DE Chill is the first DE commercial overlap fixture of its type on the market. The DE Chill is designed with an onboard ballast, is air cooled, and comes NCCS APP-ready. The air-cooled design removes up to 60% of heat load in grow facility environments. This greatly reduces the air conditioning required to maintain the growing environment at desired temperatures. The fully enclosed design uses an optical quality glass lens which only reduces light output by 6%. This 6% reduction is easily offset by the ability to lower your lights closer to your plants and therefore raising light intesities far above 20%. If left at the same height, one would only require 104 lights in a facility which would regularly require 100 open-style DE lights. The 4000W required to run the 4 additional lights and the small wattage draw for exhaust fans is minor compared to the savings from lower electrical consumption required to AC the growroom.
