The Grower's Choice 4K 1000W Double Ended CMH Bulb is a high-performance horticultural lamp designed to deliver a full-spectrum light that closely resembles natural sunlight. With a color temperature of 4200K, this bulb provides a balanced mix of blue, red, and green wavelengths, making it suitable for all stages of plant growth, from seedling to harvest. Featuring a Color Rendering Index (CRI) of 98, the 4K 1000W CMH bulb ensures high-quality light that promotes healthy plant development. It produces an initial photon flux of approximately 2,050 µmol/s, offering ample light intensity for various cultivation needs. The lamp's rated lifespan extends up to 10,000 hours, ensuring long-term reliability. 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.
