High pressure sodium (HPS) lamps are a proven choice for outdoor and industrial lighting applications where high efficiency and long lamp life take priority. Their characteristic warm amber-white light has been used for decades in street lighting, parking lots, roadways, warehouse exteriors, and security lighting. Wattages typically range from 35W to 1000W, with higher wattage options serving large-area floodlighting and industrial facilities.
HPS lamps require a correctly rated High Pressure Sodium Ballast for reliable ignition and stable operation. RelightDepot stocks standard and clear-coated bulb versions, as well as coated options for softer light distribution. Lamp life often exceeds 24,000 hours, which keeps maintenance intervals long for hard-to-reach outdoor fixtures.
Facilities managers looking to improve color rendering or cut energy costs can evaluate our HID Retrofit lamps, which fit existing HPS housings without full fixture replacement. A wider LED upgrade path is also available through our LED Light Bulbs category. For white-light high-intensity discharge applications, see our Metal Halide Lamps.
