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 APPready. The air-cooled design removes up to 60% of heat load in grow facility environments. 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%.
