Sunmaster Bulbs

This Sunmaster 600W dual spectrum HPS grow lamp puts out both red spectrum and enough blue spectrum light to be used as a sole light source throughout all stages of growing. This eliminates the need to buy separate metal halide and HPS bulbs for the vegetative and flowering / fruiting stages of plant growth.

Dual spectrum lamps are increasingly becoming a number one choice for growers as more and more are discovering these bulbs do a great job throughout all stages of plant growth. In fact, we supply most of our grow light systems with dual spectrum bulbs.
