The Growers Choice 10K 600W SE is a high-performance double-ended metal halide lamp designed specifically for the final stages of the flowering cycle. With a 10,000 Kelvin color temperature, it emits a cool blue spectrum enriched with UV-B light. Engineered for use in the last 7 to 14 days of bloom, the lamp is ideal for growers who want to maximize trichome density and overall flower quality. Its double-ended design provides superior arc stability and higher light output compared to single-ended bulbs. Built with a durable quartz glass arc tube, the 10K 600W SE maintains consistent spectral output and reliability throughout its life cycle. The lamp delivers a strong photon flux of around 650 µmol/s and a light output of approximately 36,000 lumens, with minimal lumen degradation over time. But if you want to change it up in your grow space, then check the ROI-E420 system, or the smaller 10K 600W SE lighting.
