3K-R 500W CMH Lamp

The Grower’s Choice 3K-R 500W SE CMH is a high-performance single-ended ceramic metal halide lamp designed to enhance flowering and resin production. Emitting a 3,100K spectrum, this lamp delivers a balanced mix of blue, red, far-red, and UV wavelengths, closely mimicking natural sunlight. This spectrum promotes healthy plant development, tighter internodal spacing, and increased resin production during the flowering phase. With a Color Rendering Index (CRI) of 90, the 3K-R 500W CMH lamp provides high-quality, full-spectrum light that supports optimal photosynthesis and plant development. It produces an initial photon flux of approximately 860 µmol/s, offering ample light intensity for various cultivation needs. 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.
