We carry the Halo brand of high pressure sodium grow lights that are manufactured with high quality German parts. These 1000 watt HPS grow lights have thicker and brighter reflectors made of the highest German anodized aluminum making them longer lasting than competitor brand sodium lights. Left and right sides of the reflector operate independently so one side can be deep and the other wide. The compact design creates less shadows and puts up to 30% more light on your crop – not on your walls. The 1000 watt HPS bulb gives 2,100 umols (highest on the market). The digital display of the Halo Grow Light shows useful information such as internal temperature, current wattage setting, running hours of ballast, and any problems such as voltage issue of lamp failure.
