High quality 600w HPS globe designed for the flowering stage
This Philips GreenPower 600W 400V lamp has been specially adapted to the needs of horticulture and has a higher lighting power which supplies more growth light. The lamp produces light only in the orange/red part of the spectrum for heavy flowering. It has been specifically designed to make the most of your HPS Pro (400 Volt / 600 Watt) system where it will produce more plant-useable light photons, of a better spectrum, than any other 600 Watt lamp available.
*NOTE: We recommend using this globe ONLY with 400V ballasts. Will not fire correctly on non 400V ballasts.
