High Pressure Sodium (HPS) Lamps
 
High pressure sodium (HPS) lights are the only lights comparable to metal halide growlights. They have good spectral distribution, but sodium lights can not compare to halide in the blue end of the spectrum. Just in the same way, Metal Halide lights can’t compete with HPS (high pressure sodium) in the red end of the spectrum. Sodiums are particularly high in the yellow and red regions of the spectrum. This is the type of light fruiting and flowering plants like best. Because of the focus on red light, some varieties of plants grown with sodium lights alone can become elongated and leggy.

High pressure sodium lights do, on the other hand, stimulate flower and fruit production more efficiently than halide, making them an important light source best used in conjunction with metal halide either in addition to, or cycled together. HPS (high pressure sodium) bulbs also have a much longer life expectancy than halides, lasting up to two (2) years!
