Often used in recessed can fixtures and track lighting, these bulbs produce a focused beam of light. 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. A bulb’s estimated yearly energy cost is based on 3 hours of usage per day at $0.11 per kWh.

LED bulbs last longer and are more efficient than other technologies. They generate little heat and withstand vibration. Plastic LED bulbs are shatterproof.

Halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat. Those with a glass lens will contain glass shards if the bulb breaks.

These bulbs have a bi-pin connection to lock into sockets. Often used in recessed can fixtures and track lighting, they produce a focused beam of light. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. Bulbs with a warm light appearance have yellow tones. A bulb’s estimated yearly energy cost is based on 3 hours of usage per day at $0.11 per kWh.

Halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat. They have a glass lens that will contain glass shards if the bulb breaks.

These bulbs produce a narrower, more concentrated beam of light than floodlight bulbs. Bulbs with a warm light appearance have yellow tones. Those with a neutral light appearance are commonly used in workspaces. A bulb’s estimated yearly energy cost is based on 3 hours of usage per day at $0.11 per kWh.

LED bulbs last longer and are more efficient than other technologies. They generate little heat, withstand vibration, and are shatterproof.

These bulbs are small, but very bright, so they're often used in flashlights and optical instruments such as projectors and microscopes. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

Halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat.

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.

Pulse-start bulbs restart nearly twice as fast as probe-start bulbs.

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.

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.

Energy efficient and long lasting, these bulbs are often used in task lights. They’re comparable to PL, Dulux, and Biax bulbs. It takes these bulbs several seconds to reach full brightness. 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 often used in workspaces. Bulbs with a cool light appearance have white/blue tones and are good for inspecting. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh. These bulbs contain small amounts of mercury (for disposal information, visit www.epa.gov/cfl).

Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

The sealed assembly withstands the rigors of outdoor use. In addition to using these bulbs in vehicles, they can be used for spot, flood, and emergency lighting. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

Halogen bulbs are slightly more efficient than incandescent, but they generate more heat.
