The Sunmaster Dual Spectrum HPS lamps are perfect for your whole grow, developed to give you a broader light spectrum that lasts longer.

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, and so far the feedback from our customers has been nothing but positive.

This innovative design delivers more usable red and blue light for both the vegetative and flowering stages, without depleting overall lumen output or intensity.
