T8 4ft 18W Single-Ended Power, T8 Led Bulbs 5000K, Daylight White, 18W Frosted 2520 Lumens 

The 18W available in 5000K color temperature and having a CRI of >80  can deliver lumens up to 2520. It is an excellent substitute for T8, T10 & T12 fluorescent tubes. This 18W can safely and easily replace a fluorescent tube of 65W and bring an energy savings of 47W. Thus, a lower utility bill for you every month. This 18W will work without a ballast, hence the existing ballast must be bypassed and directly wired to the line source for the tube fixture to work. These 18W LED tubes are housed in rugged die-cast aluminum for efficient heat dissipation. For the standard ceiling height, these LED tubes having a beam angle of 180 degrees emit enough bright light, have a long lifespan, and have a shatterproof coating unlike the fluorescent tubes that were of inferior light quality, typically low lifespan, and usually with no shatter proofing. One of the best things about LED Tubes from Wen Lighting is they are ETL & DLC listed when these listings make you eligible for a handsome rebate along with 5 years of warranty.
