ADL Supply Expert Application & Replacement Guide
This 32W lamp is used to re-lamp standard 4-foot T8 fixtures. Philips positions the 5000K color for daylight-balanced spaces such as warehouses and task-lighting areas. It is a drop-in lamp replacement only when the wattage, length and base match the lamp you are taking out.
ALTO lamps have a green end cap, which marks Philips' extra-low mercury design. The low mercury content makes the lamp TCLP compliant, which can reduce disposal costs in commercial and institutional buildings.
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.
