About Replacing Tubular Fluorescent Light Bulbs

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.

Xenon bulbs are known for generating a bright light, such as a flash in a camera. They last longer than halogen and incandescent 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.

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

Incandescent bulbs are traditional light bulbs. Many have been phased out due to governmental energy requirements, but some are still available for special applications.

Bulbs that cannot be sold to the listed regions do not meet energy efficiency and/or mercury regulations.

Bi-Pin Base Tubular Light 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. Bulbs with a warm light appearance have yellow tones. Bulbs with a neutral light appearance are often used in workspaces. Bulbs with a cool or daylight 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.

Fluorescent bulbs are energy efficient, but they contain small amounts of mercury (for disposal information, visit www.epa.gov/cfl). Plastic-coated glass bulbs are shatter resistant; the coating retains glass shards if they break.

Bulbs that cannot be sold to the regions listed exceed local regulatory limits on mercury and/or do not meet local efficiency standards.

Blacklight Blue Light Bulbs

Detect UV-reflective materials that are invisible to the naked eye with these bulbs. They contain a blue filter that absorbs the visible light they produce while allowing long wave ultraviolet (UV-A) light to pass through. They appear black when turned off. These bulbs are not for use in bug zappers. 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.
