High-Pressure Sodium Light Bulbs
Illuminate parking lots and roads with the warm, yellow light of these high-pressure sodium bulbs. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. Color rendering index (CRI) is a measurement on a scale of 0-100 of how accurately the light from a bulb represents an object's true colors; the higher the number, the more natural the colors appear. Any CRI value over 80 will show colors true to life. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh. Bulbs cannot be sold to Canada because they exceed local regulatory limits on mercury.
Non-cycling bulbs prevent damage to ballasts and starters because they remain off at the end of their service life instead of cycling on and off like other high pressure sodium bulbs.
An instant restart means you won’t have to wait the several minutes it takes other high-pressure sodium bulbs to restart.

Metal Halide Light Bulbs for High-Pressure Sodium Lights
Switch from the yellow light of high-pressure sodium to the white light of metal halide without changing ballasts. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. Color rendering index (CRI) is a measurement on a scale of 0-100 of how accurately the light from a bulb represents an object's true colors; the higher the number, the more natural the colors appear. Any CRI value over 80 will show colors true to life. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh. Bulbs cannot be sold to Canada because they exceed local regulatory limits on mercury content.
Bulbs with an EX39 base number will not burst when they fail.

Electronic Ballasts for Tubular Fluorescent Light Bulbs
In addition to being more energy-efficient than magnetic ballasts, these electronic ballasts are lighter and quieter. Ballasts that can operate multiple bulbs may have more wires than you need. Cover unused wires with a wire nut.
Instant-start ballasts turn on immediately. They are the most energy-efficient, but shorten the bulb's life.
