The most common HID lamps are metal halide (MH) and high pressure
sodium (HPS). Both feature long lamp life and can withstand temperature
extremes without significant loss of light output. Both sources require
time to start up and restrike. Kelvin temperature is 2,000K (a
yellowish-white color) for HPS and from 3,000 to 4,100K (a white to blue
white color) for MH. Other lamps are available to address specific global
markets. Lamp / ballast system performance may vary per manufacturer.
Certain metal halide lamps should be enclosed. Consult factory for
details.

Temperature Effect on HID Ballast/Component Life
Temperature has a tremendous effect on the life expectancy of a ballast and its related
components. Therefore, it is important not to exceed the maximum ambient rating of the
fixture. Operating a fixture in environments that are cooler than its rated ambient
temperature will greatly increase ballast life. It is generally accepted that for every 13° C drop
below the fixture's rated ambient temperature, the life of the ballast doubles. Capacitor
life is doubled when ambient temperatures drop 10° C below rating.
