The Grower’s Choice 2K 600W DE HPS lamp is a professional-grade, double-ended high-pressure sodium bulb engineered for peak flowering performance. Emitting a rich 2,000 K spectrum dominated by red and yellow hues, this lamp closely replicates natural autumn sunlight and incorporates UV and far-red peaks to enhance plant metabolism and resin production. At approximately 600 watts, it delivers around 90,000 lumens at 100 hours in, with an efficacy near 150 lumens per watt, producing an impressive photon flux ranging from 1,050 to 1,200 µmol/s. Built using a high-quality quartz arc tube, the lamp sustains spectral stability and PAR output durability, retaining about 95 % of its initial brightness even after 10,000 hours of use. But if this lighting system is too powerful for your grow space, then take a look at the ROI-E420 system, or the smaller 10K 1000W SE for better light management.
