ADL Supply Expert Application & Replacement Guide
This 28W lamp is part of the Philips Energy Advantage T8 line, which is designed for applications that need maximum energy savings. Philips positions the 4100K cool white color for cool-white commercial spaces such as offices, warehouses, schools and institutional facilities.
Philips states that the lamp operates on any instant-start or programmed-start ballast, so it can be used on the same ballast as a standard 32W T8. Starting voltage should be 550V or higher, and the lamp is not recommended where the temperature in the fixture is below 70°F. ALTO II lamps contain only 1.7 mg of mercury and are TCLP compliant, which can simplify and reduce lamp disposal costs depending on state and local regulations.
T8 lamps have a 1-inch (26 mm) tube. T8 and T12 lamps share the same G13 base, so the base alone will not tell you which type your fixture uses; match the wattage, length and lamp code printed on the end of the lamp you are replacing.
