The Grower’s Choice 2K 1000W SE is a double-ended Super HPS (High‑Pressure Sodium) lamp engineered for powerful flowering performance. Operating at 2,000 K, it delivers a rich red‑yellow spectrum with added UV content and far‑red peaks that closely mimic autumn sunlight, triggering heightened metabolic activity and resin production in blooms. With an ultra‑high photon flux of approximately 1,850–2,100 µmol/s and an efficacy of around 155 lumens per watt. Constructed with a high‑quality quartz arc tube, the lamp ensures stable spectral output and high PAR over time, maintaining about 95 % output efficiency after 10,000 hours with only ~5 % degradation. But if you want to change it up in your grow space, then check the ROI-E420 system, or the smaller 10K 1000W SE lighting.
