The Grower’s Choice 4K 1000 W DE CMH is a groundbreaking double‑ended ceramic metal halide lamp engineered to convert traditional HID fixtures into advanced CMH/LEC systems. It delivers a balanced 4,200 K full‑phase spectrum with a high CRI of 98 to support all growth stages, particularly vegetative health and bloom development. Rated at 1,000 watts, this bulb generates approximately 110,000 lumens at the 100‑hour mark—around 110 lm/W—and a photon flux of 1,930 µmol/s, providing exceptional PAR output that surpasses conventional metal halide options. The quartz‑ceramic arc tube ensures consistent spectral quality, maintaining its performance across an estimated 10,000‑hour lifespan. 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.
