ADL Supply Expert Application & Replacement Guide
The F40T8 ALTO is a 5-foot T8 for commercial fixtures designed around this lamp length. The 3500K color is a balanced, natural white that sits between warm and cool.
ALTO lamps use Philips' low-mercury design. The previous listing shows a rated average life of 24,000 to 42,000 hours, which varies with the ballast type and starting cycle.
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.
