Dimlux Daylight CMH 315W 3K Agro is a 315‑watt ceramic metal halide horticultural lamp for use in standard 315W CMH fixtures with a PGZ18 base. Its 3100 K agro spectrum is full spectrum with additional red content, making it suitable from vegetative growth through flowering. Manufacturer information lists a rated life of 30,000 hours and efficacy around 1.85–1.9 µmol/J, with total photosynthetic output near 580 µmol/s. When installed in the Dimlux Expert Series 315W fixture, typical canopy coverage is about 3' x 3' for flowering and up to 4' x 4' for veg. Use only with a compatible electronic CMH ballast and observe proper warm‑up and cool‑down intervals. This lamp serves as a replacement/add‑on bulb for Dimlux systems and other compatible 315W CMH setups.
