Halco 84887 T8 Led Lamp 12.5W 48 Inches 4000K

Product Description

The HALCO 84887 is a 4-foot T8 LED lamp rated at 12.5 watts and 4000K color temperature, designed as a direct fluorescent replacement in bypass-wired fixtures. This is a Type B lamp, meaning it operates by bypassing the existing ballast entirely and running directly off line voltage. The double-single ended bypass configuration gives installers flexibility in how line voltage is wired to the tombstones. At 12.5 watts, it delivers a significant reduction in energy consumption compared to standard 32-watt T8 fluorescent lamps while maintaining a neutral white, 4000K output suited to commercial and industrial environments.

The HALCO 84887 is used in 4-foot linear fluorescent fixtures across commercial, industrial, and institutional settings, including offices, warehouses, retail spaces, parking structures, and schools. Because it is a ballast-bypass type, it is well suited for retrofit projects where ballast replacement or elimination is preferred for long-term maintenance reduction. Electricians and lighting contractors typically install this lamp during fluorescent-to-LED retrofit programs or as a direct swap when an existing ballast has failed and ballast replacement is not desired.

Key Features

• Type B ballast-bypass design eliminates ballast dependency for improved system reliability
• Double-single ended bypass wiring supports flexible tombstone configurations
• 12.5W operation provides substantial energy savings versus 32W T8 fluorescent baseline
• 4000K neutral white color temperature suits commercial and task-lighting applications
• 48-inch T8 form factor fits standard 4-foot linear fluorescent housings

Compatibility

Designed as a Type B ballast-bypass replacement for standard 4-foot T8 fluorescent lamp fixtures. Ballast must be bypassed prior to installation; this lamp is not compatible with fluorescent ballasts.

Installation Notes

Installation must be performed by a qualified electrician in accordance with NEC requirements and the lamp manufacturer's wiring instructions. Power must be fully disconnected at the circuit breaker before rewiring tombstones for ballast bypass. Double-single ended bypass requires that line and neutral voltage be wired to opposite ends of the fixture; confirm wiring orientation before energizing. Do not install this lamp in a fixture that has not been properly rewired for bypass operation.
