SUNMASTER Conversion Grow Lamps are Metal Halide lamps which operate on standard HPS ballast and ignitor systems. The Neutral Deluxe version emits balanced light similar to a 4000° Kelvin source, while the Cool Deluxe version emits light similar to a 7000° Kelvin source, imitating the natural look of daylight.

SUNMASTER Conversion Lamps are effective in promoting both vegetative growth and flowering. They surpass the HPS lamps they replace in PAR watts - the most objective measurement of total light energy available for photosynthesis.

SUNMASTER Conversion lamps are available in 400 watt, 600 watt and 1,000 watt versions, in universal burning configurations for optimum performance, as well as cool or neutral color spectrums.
