Compared with fluorescent and incandescent lamps, high-intensity discharge (HID) lamps have higher luminous efficacy since a greater proportion of their radiation is in visible light as opposed to heat. Their overall luminous efficacy is also much higher: they give a greater amount of light output per watt of electricity input. The two types of HID used in horticulture are metal halide (MH) and high pressure sodium (HPS). The MH spectrum is preferable to plants in a vegetative phase while the HPS spectrum helps promote fruiting and flowering.
