GE F17T8/SPX41/ECO | 25W T8 Fluorescent - 24 Inch - 4100K

GE's ultra energy saving Ecolux line of lamps provides 100% longer life than standard T8s with nearly the same lumen output. As a result, you can extend group relamp cycles by over four years (assuming 4,100 annual burn hours) and significantly reduce spot relamping costs.
