Energetic Lighting’s E3T8G(2) series of LED ballast bypass T8 tubes are designed to emulate the look and feel of traditional 2-foot and 4-foot fluorescent T8 tubes.  The lens is made of a durable glass with shatter-resistant coating sleeve which contains glass pieces if tube is inadvertently broken, both engineered for maximum light diffusion as well as reliability.  Simply bypass the ballast in the existing fixture is all it takes to convert existing fluorescent fixtures into long life, energy efficient LED units.  Rated with an L70 lifetime of at least 50,000 hours, these rugged tube lamps are designed for many years of maintenance-free operation.
