SYLVANIA FP28/865/ECO 28W 6500K Daylight 45.24 in | T5 Fluorescent Bulb | G5 Bi-Pin

The Sylvania 20990 FP28/865/ECO Pentron 4-Foot T5 Fluorescent Lamp is a high-efficiency linear fluorescent tube engineered for commercial, office, and retail ambient lighting environments. Operating at 28 watts, this slim-profile T5 lamp delivers a vivid 6500K daylight color temperature with a high 85 CRI for superior color crispness. Measuring a precise 45.24 inches maximum overall length, this lamp utilizes a G5 miniature bi-pin base and is engineered with Ecologic technology to pass federal TCLP mercury standards.

ADL Supply Expert Application & Replacement Guide

The Sylvania FP28/865/ECO is a High-Efficiency (HE) standard-output T8/T12 replacement tube widely used in modern low-profile commercial troffers, multi-lamp office layout arrays, indirect cove lighting, and high-end retail displays. Delivering a vivid 6500K daylight spectrum, it aids visual focus and minimizes eye strain in detailed work environments like design studios, packaging bays, and institutional spaces.

Ballast Warning for Installers: This is a standard 28-watt High Efficiency (HE) lamp. Electrical contractors must verify that the electronic control gear inside the fixture is specified for standard 28W T5 operation. Do not install this tube on high-output 54W T5HO ballasts, as over-driving standard lamps will lead to immediate cathode failure, rapid end-of-life blackening, and potential socket melting. Furthermore, ensure the pin mounts seat cleanly inside the G5 miniature sockets—due to the ultra-slim 5/8-inch tube diameter, sockets can become fragile over long maintenance cycles.

Operation, Safety & Mounting Compliance

Thermal Peak Performance Settings

Unlike legacy T8 or T12 systems that achieve peak lumen output at an ambient temperature of 25°C (77°F), standard T5 linear fluorescent systems are engineered to achieve maximum lumen output at 35°C (95°F). This makes them exceptionally efficient inside compact, enclosed commercial luminaires where heat accumulates naturally over extended operational shifts.

Low-Mercury Environmental Compliance

This lamp features Sylvania’s proprietary ECO formulation, containing reduced mercury and meeting strict EPA Toxic Characteristic Leaching Procedure (TCLP) test standards. While eco-friendly, it still contains trace mercury elements and should be managed via automated localized commercial recycling programs during whole-facility relamping projects.
