About Brightness and Light Appearance

Find the right lumen level to brighten your space. Then, compare the way warm, neutral, and cool lighting affect the appearance of everyday objects.

About Replacing Tubular Fluorescent Light Bulbs

Spiral

Medium (Standard Household)

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.

CFL (compact fluorescent) bulbs are more energy efficient and last longer than halogen bulbs. It takes several seconds for them to reach full brightness. They contain small amounts of mercury (for disposal information, visit www.epa.gov/cfl).

Bulbs that cannot be sold to the listed areas are restricted due to energy efficiency requirements, mercury regulations, and product registration requirements.

Bi-Pin Base Tubular Light Bulbs

T5 and T5/HO

T12

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).

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

Recessed Double-Contact Base Tubular Light Bulbs

T8 and T8/HO

T12/HO

Replace existing fluorescent light bulbs that have recessed contacts or upgrade them to LED. Select a light appearance to match your existing lighting. Bulbs with more than one light appearance have a switch so you can match other lights in the room.

LED bulbs last longer and are more efficient than fluorescent bulbs. To install these bulbs, bypass the ballast by wiring the socket directly to the power source. Use them in fixtures with double-ended wiring, where the power is wired to both sockets.

Fluorescent bulbs contain small amounts of mercury. For disposal information, visit www.epa.gov/cfl. They cannot be sold to the listed areas because they do not meet local regulations for mercury content or energy efficiency.

Plastic-coated glass bulbs are shatter resistant. If the glass breaks, the coating keeps shards from falling.

Single-Pin Base Tubular Light Bulbs

T12

Swap new fluorescent light bulbs into your single-pin base fixture, or upgrade them to LED. Select a light appearance to match your existing lighting. Bulbs with more than one light appearance have a switch, which allows you to match other lights in the room.

LED bulbs last longer and are more efficient than fluorescent bulbs. They work with sockets that are wired directly to the power source. Ballast compatible bulbs also work with most instant-start electronic ballasts. Check if your ballast is compatible by selecting a part number and clicking product detail. T8 bulbs can be used in T12 sockets that are wired directly to a power source.

Plastic-coated glass bulbs are shatter resistant. If the glass breaks, the coating keeps shards from falling.

U-Shaped Tubular Light Bulbs

T12

Replace the U-shaped fluorescent bulbs in your fixture or upgrade to LED. These bulbs are often used in 2'×2' ceiling lights. Select a light appearance to match your existing lighting. Bulbs with more than one light appearance have a switch which allows you to match other lights in the room.

LED bulbs last longer and are more efficient than fluorescent bulbs. They’re compatible with most instant-start electronic ballasts, or you can use them in sockets wired directly to the power source. Check if your ballast is compatible by selecting a part number and clicking product detail. These bulbs are made for T8 sockets, but can be used in T12 sockets that are wired directly to a power source.

Fluorescent bulbs contain small amounts of mercury. For disposal information, visit www.epa.gov/cfl. Bulbs that cannot be sold to the listed areas do not meet local regulations for mercury content or energy efficiency.

O-Shaped Tubular Light Bulbs

Swap new circular CFL bulbs into your fixture or upgrade to LED. These bulbs are often used in illuminated workstation magnifiers. Select a light appearance to match your existing lighting. Bulbs with more than one light appearance have a switch that allows you to match other lights in the room.

LED bulbs last longer and are more efficient than CFL bulbs. They work with most electronic ballasts, so you can use them in existing fixtures without rewiring the socket. Check if your ballast is compatible by selecting a part number and clicking product detail.
