18 Watt T8 LED - 4 Foot - Recessed Double Contact base - 50000 Average rated hours - 2500 Lumens - Type B - Ballast Bypass - Double Ended Wiring

Upgrade Your High-Output Lighting with Superior Efficiency

Stop settling for flickering tubes and rising energy costs. The Satco 18-Watt T8 LED is the professional-grade solution for replacing power-hungry 63-watt fluorescent bulbs. Designed specifically for fixtures requiring a Recessed Double Contact (R17d) base, this 4-foot lamp delivers a staggering 2,500 lumens of crisp, consistent light while slashing your energy consumption by over 70%.

This "Type B" bulb is engineered for a direct-wire, ballast-bypass installation. By removing the ballast from the circuit, you eliminate a common point of failure and drastically reduce future maintenance overhead. The double-ended wiring design ensures a faster, safer retrofit process in existing fixtures, making it the top choice for large-scale facility upgrades and commercial renovations.
