Case of 24 T8 fluorescent tubes delivering 15 W, 1200 lm at 3500 K with a G13 base
This case contains 24 GE Lighting F17T8/XL/SPX35WMEC straight T8 fluorescent tubes. Each 15 watt lamp delivers 1200 lumens at a 3500K colour temperature. The 24 inch length and medium bi-pin G13 base suit standard commercial fixtures. Supplied new in a bulk pack for facility maintenance.
Verify that existing luminaires accept 24 inch T8 tubes with a G13 base before ordering. Confirm the installed ballast is rated for 15 watt T8 operation and matches the supply voltage. Ensure the fixture length and lamp holders accommodate the 24 inch form factor without modification.
These 15 watt XL lamps directly replace F17T8 tubes of the same length and base type while reducing power draw. The upgrade is worth it when lowering energy cost across many fixtures is a priority and the slightly lower lumen output meets the lighting design. Not suited for fixtures requiring higher output or different colour temperatures.

This model is 15 watts and 1200 lumens; select a different wattage only if your ballast and fixture are rated for it.
In a compatible 24 inch T8 fixture with a matching ballast the lamp delivers 1200 lumens at 3500K; actual perceived brightness depends on fixture optics and ballast factor.
