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.
