Operating at 80 watts, this slim-profile T5HO lamp delivers a high-lumen output of crisp 4100K cool white light with an 85 CRI for exceptional visual acuity. Built with eco-friendly ALTO technology and a standard G5 miniature bi-pin base, it offers a long-lasting 24,000-hour rated average service life when paired with compatible high-frequency electronic ballasts.

ADL Supply Expert Application & Replacement Guide

The Philips F80T5/841/HO/ALTO is a high-intensity industrial light source commonly deployed in warehouse high-bay fixtures, manufacturing spaces, distribution centers, large retail perimeters, and indirect architectural cove systems. Delivering a crisp 4100K cool white spectrum, it maintains optimal visibility and reduces glare in fast-paced operational workspaces, supporting overall safety and productivity for personnel.

Ballast & Mounting Specifications for Field Technicians: This is an 80-watt **High Output (HO)** linear source and must be operated exclusively on high-frequency electronic ballasts specified for 80W T5HO operation. Do not attempt to run this lamp on standard 28W T5 or 54W T5HO control gear, as mismatched currents will cause rapid end-of-life blackening, socket failure, or immediate ballast shutdown. Measuring a maximum overall length of 58.0 inches, this 5-foot class lamp requires 600V-rated G5 miniature sockets. Ensure the pin mounts twist and lock fully into place to maintain a continuous, arcless circuit path across long duty cycles.

Operation, Safety & Mounting Compliance

High-Temperature System Performance

Unlike older T8 or T12 linear systems engineered for peak performance at 25°C (77°F), commercial T5HO lamps are thermally optimized to hit maximum lumen efficacy at an ambient temperature of 35°C (95°F). This structural design criteria makes them exceptionally stable when deployed in tightly enclosed industrial high-bays or commercial troffers where heat accumulates naturally over extended operational shifts. This lamp supports universal burning orientations, allowing seamless vertical or horizontal mounting.

ALTO Low-Mercury Environmental Compliance

This linear tube utilizes Philips' patented ALTO technology, featuring an advanced capsule design that drastically reduces heavy-metal mercury content while passing the EPA's Toxic Characteristic Leaching Procedure (TCLP) non-hazardous benchmarks. While environmentally sustainable for conscious corporate maintenance programs, these bulbs should still be collected and managed through localized commercial lamp recycling facilities during full property relamping phases.
