Light Efficient Design 4ft LED T8 Tube - 18W | 4000K | 120-277V AC

The Light Efficient Design 4ft LED T8 Tube, model LED-6115-4-40K-TFR, is specified at 18W, 4000K. Consider this model where a T8 tube is specified for a compatible troffer, strip or other socketed luminaire. The existing housing determines how the lamp’s light is distributed. This 4000K version is useful for keeping a consistent colour across the break room or work area during a replacement project. Use 2200 lumens as the lamp-output reference for the occupied area below the fixture, allowing for the fixture diffuser and the number of lamps operating together.

For the 48-inch T8 installation, select the circuit for this 18W lamp rather than using length as the only compatibility check. Confirm the exact wiring arrangement for this model before replacement; the lamp format alone does not determine ballast or direct-wire operation.
