Lumatek 400W Metal Halide Bulb 4000K

This Lumatek MH 400W 240V, pulse start lamp, has been designed for use with the Lumatek 400W 240V electronic ballast and was engineered using high-temperature resistant quartz arc tube technology and a specific horticultural gas mix that creates optimal spectral output for healthy plant growth. The quartz arc tube allows the lamp to operate at high internal temperatures increasing color rendering, output and efficiency. Pulse start technology allows for faster start-up and re-strike times, longer lamp life and increased PAR/PPF level maintenance.
