HPS grow light fixtures are closed, professional luminaires with built-in electronics and an optimised reflector. This collection features the Supreme OPTIC A 1000W and OPTIC PRO 1000W, both dimmable, for growers who want a robust, efficient HPS solution for larger areas. A fixture like this typically lights around 1.2 to 1.5 m² and is hung higher than a 600W reflector to spread the light evenly. Plan your extraction and ducting accordingly, as 1000W adds a lot of heat. Spare bulbs are in 1000W HPS lamps; for a cooler alternative see full spectrum LED lights.
