Rab T8-15-48P-835-DIR Led T8 Lamp 15W 3500K Direct Wire

Product Description

The RAB T8-15-48P-835-DIR is a direct-wire LED T8 replacement lamp designed for use in linear fluorescent fixtures. Running at 15 watts with a 3500K color temperature, this lamp delivers neutral white light suited to commercial and industrial environments where accurate color rendering and energy efficiency are both priorities. At 48 inches in length, it fits standard 4-foot T8 lamp positions. Direct-wire configuration bypasses the existing ballast entirely, connecting the lamp straight to line voltage for a cleaner, more reliable installation with no ballast to fail or replace down the road.

This lamp is appropriate for retrofit projects in offices, warehouses, retail spaces, schools, and similar commercial interiors currently running fluorescent T8 systems. It is installed by licensed electricians performing ballast-bypass retrofits, as well as lighting maintenance technicians working in facilities with 4-foot linear fixtures. The 3500K color temperature is a neutral white commonly specified for task and ambient lighting in commercial interiors.

Key Features

• 15-watt direct-wire operation eliminates ballast dependency
• 3500K neutral white color temperature for commercial task and ambient lighting
• 48-inch form factor fits standard 4-foot T8 fixture positions
• Ballast-bypass design reduces ongoing maintenance and failure points
• LED light source for reduced energy consumption compared to fluorescent T8 lamps

Compatibility

Designed as a direct-wire ballast-bypass replacement for standard 4-foot T8 fluorescent lamp positions. Requires rewiring of the fixture to line voltage; not compatible with ballast-driven installations without modification.

Installation Notes

Installation must be performed by a licensed electrician. The existing ballast must be disconnected and removed, and the tombstone sockets must be rewired to accept direct line voltage before installing this lamp. Power must be fully shut off at the circuit breaker before any wiring work begins. Follow all applicable NEC requirements for the fixture type and installation environment.
