The Norman Lamps FL20SD is a 20W T10 linear fluorescent tube designed for use in compatible fluorescent fixtures requiring a G13 medium bi-pin base. Operating at 6500K, this daylight-spectrum fluorescent tube delivers crisp, bright illumination that closely resembles natural outdoor light, making it well suited for task lighting, display lighting, retail environments, workshops, and general-purpose applications where accurate color perception is important. The T10 tube measures 23.25 inches in length (not including pins) with a 1.25-inch diameter, providing a direct fit for fixtures originally designed around this lamp format. Rated at an average of 15,000 life hours, the FL20SD offers an extended service life that reduces the frequency of replacements in regularly occupied spaces. This fluorescent tube serves as a replacement for the FL20SS-W/18 and is sold individually as a single unit.
