Upgrade your lighting with this high-efficiency LED lamp, designed as a Ballast Bypass or Type B LED. This lamp is the ideal replacement for a Cool White (4100 Kelvin) 4-foot T12 fluorescent tube. While installation requires minor electrical work—bypassing the ballast and running line voltage directly to the sockets—the long-term benefits are significant. Eliminating the ballast reduces future maintenance, saving you time and hassle.

This LED lamp consumes only 11.5 watts, reducing energy consumption by over 70%. It delivers a bright 1800 lumens and is engineered to last, with a lifespan of 50,000 hours. For most applications, a 1-for-1 replacement will likely provide adequate light while maximizing energy efficiency. Additionally, it comes with a 5-year manufacturer’s warranty and does NOT contain mercury, offering you peace of mind and long-lasting performance.
