B-Lite 500W CMH Agro 4K Lamp

A 500W CMH Bulb With a 4100K Spectrum

SupremeLux B-Lite lamps are built with an adjusted horticultural spectrum for consistent, high-performance growth. This 500W ceramic metal halide lamp is rated at 4100K with a color rendering index above 90. At 100 hours it produces 60,000 lumens, or 120 lumens per watt. Photon output measures 950 µmol/s, the figure that matters most for plant growth. Rated life is 15,000 hours at 10 hours per start. The arc tube is polycrystalline alumina, and the outer bulb is quartz glass. It runs horizontally, in open or enclosed fixtures. The lamp operates at 120V and 4.0A, with a starting pulse of 3 to 4 kV. It runs on an ANSI C182/O ballast or a compatible electronic ballast. The cooler 4100K balance leans toward blue, which suits vegetative growth and compact plant structure.

Seasoning and Running a 4100K CMH Lamp

New lamps need a seasoning period of about 100 hours while the salts inside the arc tube burn in. A slight pulsing during that time is normal, and the lamp settles to full performance afterward. Always unplug the fixture before changing a lamp, and wear clean gloves to keep oils off the glass. Check that the end wires are straight and the glass is free of cracks before installing. Keep lamps dry, and never run one above or below its rated voltage or current. Avoid running the lamp around the clock, since constant operation shortens its life. HID lamps run hot and emit strong UV, so use proper eye protection and keep fabric and paper away. This is a non self-extinguishing lamp; a broken outer bulb can release shortwave UV that burns skin and eyes. Replace lamps at the end of their rated life, since old lamps are more prone to bursting. Many growers pair it with a warmer lamp later in the cycle.
