About Sunmaster
Why Sunmaster
Sunmaster has made horticultural lamps for decades and its Super HPS is one of the best-value 600W flowering lamps there is. The metal halides give the blue spectrum for growth, and the 400V lamps deliver the most light per watt on a compatible ballast.
Lamp life
Change lamps after about a year of use even if they still light; output fades long before they fail. Ballasts and reflectors are under HID Lighting.
