GE Lighting 71644 26W 2900lm 4100K T5 Fluorescent Bulb

40-count T5 case

This case contains 40 GE Lighting 71644 linear fluorescent tubes. Each 45.2-inch lamp uses a 0.6-inch diameter T5 design with a miniature bi-pin G5 base. The cool white 4100K output suits commercial offices, retail displays and workshop task lighting. Buyers needing a different colour temperature or a non-T5 form factor should choose another product.

G5 base and ballast dependence

The miniature bi-pin G5 base fits only fixtures wired for T5 lamps with a compatible electronic ballast. Mismatched ballasts will prevent starting or reduce lamp life. The 26-watt draw assumes correct ballast operation; actual system power may differ. Installations without a G5 socket or without a T5-rated ballast cannot use these lamps.

2900-lumen output and 11.4-year rating

At 2900 lumens each tube delivers bright cool-white light for general illumination. The 11.4-year life rating is based on six hours of daily operation; longer daily runs will shorten calendar life. Spaces requiring higher lumen density or instant restrike after power loss will find these lamps insufficient.
