GE Lighting 97319 F15T8SP35 15 W T8

The GE Lighting 97319 F15T8SP35 is a 15 watt linear fluorescent tube designed for office and work spaces. It measures 18 inches in length and uses a T8 form factor with a Medium Bi-Pin G13 base. The lamp produces 940 lumens at a 3500K colour temperature for bright white illumination. This product is sold as a case of six lamps for commercial or residential fixtures.

Case of six lamps simplifies bulk replacement

The case of six lamps allows facilities teams to stock spares and complete group relamping in a single order. Having multiple units on hand reduces downtime when individual tubes reach end of life. The pack format suits maintenance schedules for drop-ceiling troffers, under-cabinet fixtures and task lighting. Each lamp is ready to install without additional accessories.

15 W 940 lm output fits standard T8 fixtures

At 15 watts the tube delivers 940 lumens, a level suited to general-purpose lighting in offices, corridors and workshops. The 3500K bright white tone balances warmth and clarity for reading and detailed work. It is not intended for high-bay areas or applications requiring higher lumen packages. Builders needing greater output or different colour temperatures should select alternative models.

Questions about this item

When will the 15 W T8 tube need replacing?

The 940 lm output will gradually decline; plan to replace the lamp once light levels drop below the needs of your 3500 K workspace.

What limits continuous operation of the 18 in F15T8SP35?

The 15 watt rating and G13 bi‑pin base set the electrical limit; sustained use is bounded by the ballast and fixture thermal design.

How much heat and noise does the 97319 produce all day?

A 15 W linear fluorescent runs cool and silent; the only audible sound may come from the external ballast, not the tube itself.
