This pulse-start lamp has been engineered for use with Lumatek 400W 240V electronic ballast and is produced using high-temperature resistant quartz arc tube technology and specific horticultural gas blend that creates optimal spectral output for healthy plant growth.

The quartz arc tube permits the lamp to operate at high internal temperatures increasing colour rendering, output and efficiency. Pulse-start technology enables faster start up & restrike time, longer lamp life and increased PAR/PPF level maintenance.
