The Sunmaster 250 Watt Metal Halide Conversion Lamp uses existing HPS lighting systems to minimize conversion costs. Conversion Grow Lamps are Metal Halide lamps which operate on standard HPS ballast and ignitor systems. This conversion lamp converts HPS to Metal Halide allowing the HPS ballast to produce the blue spectrum that promotes plant growth. This Neutral Deluxe conversion bulb from Sunmaster emits balanced light similar to a 4000° Kelvin source.
