LED Light Bulbs for High-Intensity Discharge (HID) Lights







Replace high-intensity discharge (HID) lights with the longer-lasting, energy-efficient LEDs. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. LED lights are perceived as brighter at night than high-intensity discharge light technologies, so they require fewer lumens to provide the same brightness. Match your old light’s wattage to find the right LED bulb. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh.
Ballast bypass bulbs eliminate the need for a ballast, so the socket must be wired directly to the power source.

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.

Light Meters



Measure light quality and intensity with these meters. They shut off automatically to preserve battery life. These meters are CE marked, so they meet European safety standards. They should not be used with lasers.
Use the data hold function to freeze a measurement on the screen, giving you time to write it down. Some meters also have an analog output, which transmits data to a recorder. Meters with minimum/maximum memory let you save and retrieve the high and low measurements you’ve taken.
Styles A-C measure brightness in footcandles and lux. One footcandle is one lumen per square foot. One lux is one lumen per square meter. All of these meters measure general lighting. Style A meters also measure white LED light, and Style B meters measure colored LED light. Style C meters measure general lighting only – they are not for use with LED lights.
