About Replacing Tubular Fluorescent Light Bulbs

About Brightness

About Light Appearance

T5 and T5/HO

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.

LED bulbs last longer and are more efficient than fluorescent bulbs. They generate little heat and withstand vibration. Socket-ready bulbs work with most instant-start electronic ballasts, but not all. For a full list of compatible ballasts select a part number and view product detail. Ballast bypass bulbs eliminate the need for a ballast so the socket must be wired directly to the power source.

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.

Ultraviolet Light Bulbs

Disinfect and sterilize air, water, and surfaces with short wave ultraviolet radiation. Ultraviolet radiation is harmful to skin and eyes; only install bulbs in fixtures that provide adequate protection. 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 due to import regulations.

Linear Bay Lights

With a lower profile design than other bay lights, linear bay lights mount closer to ceilings, providing more room for racks or shelving. Use them in large, open areas such as warehouses and manufacturing spaces where the ceiling is up to 40 ft. high. Rated for use in damp locations, these lights withstand humidity and moisture. They can be hardwired to operate on any of the voltages listed.

Style A and C lights require suspension hardware (sold separately), which includes two wire rope slings with hooks and two wire rope clamps. No tools required—adjust the length of the suspension hardware and tighten the clamps to secure.

Lights without bulbs work with tubular fluorescent bulbs (sold separately).

Lights with an aluminum housing are lightweight and resist corrosion better than those with a steel housing.
