HPS Grow lights have good spectral distribution. High Pressure Sodium Grow Lights emit the yellow and red regions of the spectrum. High pressure sodium bulbs stimulate flower and fruit production in plants more efficiently than any other grow light source. HPS Grow Lights are best used in conjunction with metal halide grow lights either in addition to, or cycled together. HPS (high pressure sodium) bulbs also have a much longer life expectancy (20,000 hrs) compared to Metal Halide Bulbs. Please contact us for any assistance you might need.
