Available in 17.5 and 15 W, 4 ft models, as well as 9 W, 2 ft version, T8 BYP LED Tubes combine micro-designed driver and compact light engine that produces light emitting area of 325°. Units have coated glass body to diffuse heat and light evenly. Wide beam angle and glass diffuser maximize total light distribution while replicating traditional fluorescent tube lighting effect. Operating directly off 120–277 V line voltage, DLC®-qualified units eliminate ballast-related compatibility problems.
