Sylvania 25150 F48T12/D/HO

The Sylvania Lifeline® T12 High Output 25150 F48T12/D/HO 60W Daylight High output Lamp is a commercial-grade, heavy-duty high-intensity linear fluorescent bulb engineered for industrial warehouses, outdoor signs, cold-storage facility boxes, loading docks, and manufacturing plants. Delivering 3,600 initial lumens of crisp 6500K daylight illumination, this rugged 60-watt tube utilizes an advanced gas mixture to achieve a color rendering index of 76 CRI. Outfitted with robust R17d Recessed Double Contact (RDC) bases and a wide 1.50-inch glass envelope diameter, it provides a reliable 12,000-hour rated average service life when driven by high-current 800mA rapid-start ballast networks.

ADL Supply Expert Application & Replacement Guide

The Sylvania F48T12/D/HO high-output linear lamp is an established heavy industrial maintenance baseline specified universally across manufacturing centers, loading dock bays, external commercial signs, and parking garage canopy lines. Utilizing an enhanced daylight gas filling composition, its 6500K spectrum provides exceptional spatial contrast and crisp visibility across high-traffic safety corridors, helping plant operations match pre-existing architectural visual tracks without incurring the high labor and electrical conversion costs of complete fixtures overhauls.

Critical 800mA High-Output Current Tracking and Telescoping R17d Base Controls: Facility crews executing routine site maintenance loops must carefully verify control gear electrical restrictions prior to cart checkout. This specialized 4-foot T12 tube functions strictly when connected to a high-amperage 800mA electronic or magnetic rapid-start ballast circuit. Attempting to force this high-output lamp into standard medium bi-pin fluorescent paths or uncalibrated T8 troffer electronics will prompt immediate ignition drop-out, rapid electrode degradation, or complete circuit board non-performance, as standard lines deliver only 265mA.

Furthermore, check the socket profile to ensure physical seating: the **R17d recessed double contact base utilizes two spring-loaded recessed push paths**. This tube spans exactly **46.00" Inches** from tip to shoulder, fitting natively inside commercial 48-inch high-output luminaires. Push one end firmly into the spring telescoping lamp-holder, compress slightly, and align the opposite base to snap it securely into position.

Operation, Safety & Mounting Compliance

High-Frequency Electronic vs. Magnetic Core Sign Transformation

When retrofitted onto modern high-efficiency electronic 800mA ballasts, this lamp operates at frequencies exceeding 40 kHz, completely eliminating stroboscopic workplace eye fatigue and structural flickering loops common in old low-frequency magnetic systems. It incorporates an automated active surge insulation barrier that blocks standard utility switching transients and operational spikes from breaking down sensitive internal solid-state board capacitors.

Mercury Content Dosing and Safe Bulk Recycling Protocols

This gas-discharge tube incorporates a metered heavy-metal mercury fill vapor dose inside its inner linear chamber to execute its continuous light generation pathway. While engineered to minimize tracking degradation and maintain stable mean lumen metrics over extended service life, it remains a hazardous component. National safety codes dictate processing spent lamps through certified commercial bulk recycling repositories during facility maintenance sweeps rather than discharging them into standard residential or municipal solid waste streams.
