About Brightness

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.

Bi-Pin Base Tubular Light Bulbs

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). 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

T12

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 the listed areas because they exceed local regulatory limits on mercury.

Sockets for Tubular Light Bulbs

Replace worn sockets in light fixtures. These sockets work with tubular fluorescent bulbs, and some also work with LED bulbs.

Sockets for rapid and preheat ballasts are also known as non-shunted.

Sockets for instant-start ballasts are also known as shunted.

Electronic Ballasts for Tubular Fluorescent Light Bulbs

In addition to being more energy-efficient than magnetic ballasts, these electronic ballasts are lighter and quieter. Ballasts that can operate multiple bulbs may have more wires than you need. Cover unused wires with a wire nut.

Instant-start ballasts turn on immediately. They are the most energy-efficient, but shorten the bulb's life.

Rapid-start ballasts have a slight turn-on delay, but are gentler on bulbs than instant-start ballasts so bulbs last longer.
