Rab T5HO-25-48G-850-SD-BYP 25W T5HO Led Tube 4 Ft 5000K

Product Description

The RAB T5HO-25-48G-850-SD-BYP is a T5HO-base linear LED tube designed to replace fluorescent lamps in ballast-bypass applications. Rated at 25 watts and delivering 3,500 lumens, this 4-foot glass tube operates at 5000K (daylight) color temperature with a minimum 80 CRI. It supports both single-ended and double-ended wiring configurations, making it flexible for a wide range of retrofit scenarios. Electricians and lighting contractors install this tube when upgrading fluorescent fixtures to direct-wire LED operation, eliminating ballast dependency and reducing long-term maintenance overhead.

This tube is suited for commercial, industrial, and institutional settings where T5HO fluorescent fixtures are currently installed. Typical applications include warehouses, office spaces, retail environments, gymnasiums, and parking structures. The ballast-bypass design means the existing ballast is disabled or removed and the fixture is rewired to deliver line voltage directly to the tombstone sockets. Both single-ended (one live end) and double-ended (live on both ends) wiring methods are supported, giving installers flexibility based on fixture type and local wiring preference.

Key Features

• 25-watt consumption with 3,500-lumen output for efficient T5HO retrofit performance
• 5000K daylight color temperature with 80 CRI minimum for accurate color rendering
• 4-foot glass tube body compatible with standard T5HO fixture lengths
• Single-ended and double-ended ballast-bypass wiring both supported
• Direct-wire ballast bypass eliminates ballast failure as a maintenance point

Compatibility

Designed as an OEM-style replacement LED tube for 4-foot T5HO fluorescent fixtures configured for ballast-bypass direct-wire operation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC requirements and applicable local codes. Power must be shut off at the breaker before rewiring fixture sockets for direct-line voltage operation. Confirm whether single-ended or double-ended wiring is required for the specific fixture before installation, as mixing configurations can create a shock hazard. Do not install this tube in fixtures that retain an active ballast, as it is not ballast-compatible.
