The Grower’s Choice 4K 1000 W DE CMH is a groundbreaking ceramic metal halide lamp that transforms standard DE HID fixtures into elite CMH/LEC lighting systems. With a daylight-balanced 4,200 K spectrum and an exceptionally high CRI of 98, it replicates natural sunlight, delivering remarkably accurate color rendering and supporting plant development through every stage, especially vigorous veg growth and bloom initiation. At full power (1,000 W), this lamp produces approximately 110,000 lumens at 100 hours, achieving around 110 lumens per watt, and emits about 1,930 µmol/s of photon flux. 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.
