ADL Supply Expert Application & Replacement Guide

A U-bend lamp puts a 4-foot lamp length into a roughly half-size footprint, which is why it is used in 2x2 troffers in offices, schools and healthcare buildings. The previous listing shows Energy Star and RoHS certifications for this lamp.

The 4100K cool white color is a crisp, clean light common in workplaces. Leg spacing is 6 inches (the /6 in the lamp name), so the lamp only fits fixtures built for that spacing.

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.
