The Grower’s Choice 3K 630W DE CMH is a breakthrough double-ended ceramic metal halide (CMH/LEC) lamp designed to transform any DE fixture into a more efficient CMH system. With a balanced 3000 K spectrum, it closely mimics natural sunlight by combining blue, red, far‑red, and UV emissions. This full-spectrum approach promotes stronger internodal spacing, improved resin production, and robust flower development compared to traditional HPS or MH lights. Rated at 630 W, the lamp delivers a powerful initial photon flux of around 1,100 µmol/s, with a CRI of approximately 85, ensuring vibrant coloration and accurate plant growth signals. Designed for use in double-ended electronic ballasts, the Grower’s Choice 3K 630W CMH seamlessly replaces existing DE bulbs, offering a clean, energy-efficient lighting upgrade. 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.
