The Norman Lamps F20T12-D is a 20W T12 fluorescent tube engineered for 2-foot fixtures requiring a crisp, full-spectrum daylight output. Operating at 6500K, this fluorescent tube produces light that closely simulates natural outdoor daylight, making it well suited for environments where accurate color perception and high visual clarity are priorities. At 1350 lumens, the lamp delivers consistent, uniform illumination across its 24-inch length and 1.5-inch T12 diameter profile.

The F20T12-D fits the industry-standard G13 medium bi-pin base, making it a direct drop-in replacement for any 2-foot T12 fluorescent fixture and ballast designed for F20T12 lamps. The 6500K daylight color temperature is a popular choice for task-oriented spaces such as offices, retail display areas, workshops, garages, basements, and light industrial or clean-room environments where a bright, cool white light that renders colors accurately is beneficial.

This T12 fluorescent tube carries an average rated life of 10,000 hours, providing extended service intervals that help reduce the frequency of lamp replacements in maintained fluorescent systems. Like all fluorescent lamps, it contains a small amount of mercury and should be recycled through an appropriate program at end of life. The Norman Lamps F20T12-D is sold individually and is also available in a full case quantity of 20 units for facilities requiring bulk stock of this 2-foot daylight fluorescent tube.
