Keystone Kt-led18.5t8-48gc-840-dx2 /g2-cp Led T8 Lamp 18.5W

Product Description

The KEYSTONE TECHNOLOGIES kt-led18.5t8-48gc-840-dx2 /g2-cp is a 4-foot T8 linear LED lamp from the 800 DirectDrive DX2 Series, designed as a direct ballast-bypass replacement for fluorescent tube fixtures. Running at 18.5 watts, it delivers 2500 lumens at a 4000K neutral white color temperature with a frosted tubular bulb finish. The lamp operates across a wide voltage range of 120 to 277 VAC and is rated for an average life of 50000 hours. It is installed by licensed electricians and qualified lighting technicians performing retrofits in commercial, industrial, and institutional facilities.

This lamp is suited for ballast-bypass (direct-wire) retrofit installations in standard 4-foot T8 fluorescent fixtures found in offices, warehouses, schools, retail spaces, and similar commercial environments. It supports both double-ended and single-ended wiring configurations, giving installers flexibility during retrofit. The instant-start design eliminates ballast compatibility concerns entirely, making it a clean, long-term upgrade from fluorescent technology.

Compatibility

Designed as a direct-wire ballast-bypass replacement for standard 4-foot T8 fluorescent fixtures with G13 bi-pin lamp sockets rated for 120 to 277 VAC single- or double-ended wiring configurations.

Installation Notes

Ballast-bypass installation must be performed by a licensed electrician following NEC requirements and local electrical codes. The existing ballast must be disconnected or removed and line voltage wired directly to the tombstone sockets before installing the lamp. Always shut off and lock out power at the circuit breaker before beginning any wiring work. Verify socket type and wiring configuration (single-ended or double-ended) matches the lamp wiring diagram before energizing.
