Product Overview
The Sylvania FP21/865/ECO is a 21W linear T5 fluorescent lamp on a G5 miniature bi-pin base, used in office, retail, utility and general maintenance fixtures.
T5 lamps use a slim 5/8" diameter tube and a G5 miniature bi-pin base, which is not interchangeable with T8 (G13) or T12 sockets. Matching the exact wattage, length, ballast type and color temperature is important to avoid compatibility problems.
