Screw-In Base Light Bulbs
Use these bulbs in standard sockets, panels, and appliances. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. Bulbs with a warm light appearance have yellow tones. Bulbs with a neutral light appearance are commonly used in workspaces. Bulbs with a cool or daylight appearance have white/blue tones and are good for inspecting. A bulb’s estimated yearly energy cost is based on 3 hours of usage per day at $0.11 per kWh.
Incandescent bulbs are traditional light bulbs. Many have been phased out due to governmental energy requirements, but some are still available for special applications.

Metal Halide Light Bulbs
Bulb with
E39 Base
Illuminate large warehouses, factories, and arenas with the bright, white light of these metal halide 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 with an EX39 base number will not burst when they fail.
Pulse-start bulbs restart nearly twice as fast as probe-start bulbs.
Plastic-coated glass bulbs are shatter resistant; the coating retains glass shards if they break.
Bulbs that cannot be sold to the listed areas exceed local regulatory limits on mercury content.

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.
Plug socket-ready bulbs into an existing fixture with a compatible ballast.
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.

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 with an EX39 base number will not burst when they fail.

Broken Light Bulb Removers
Insert removers into broken bulbs and twist to take the bulbs out. A built-in tray collects the glass shards. They require an add-on pole (sold separately). Connect up to four add-on poles to extend your reach.
