The D50 Lighting™ T8 LED tube is designed to directly replace 4-ft T8 fluorescent lamps (F32T8), and can be directly installed into an existing 4-ft fluorescent fixture regardless of its configuration. ReadyWire™ technology ensures that the LED lamp will work with your fixture, with or without the fluorescent ballast, and whether or not it is single or double-ended.

The best way to determine if these lamps will fit and operate in your current fixture is to confirm the specifications of the fluorescent lamp that is currently installed in your fixture.

First, determine the length of the fluorescent lamp that is currently installed. If it is 4-ft (48") in length and has a 1 inch diameter, you have a T8 4-ft fluorescent lamp, which means that our lamp is compatible. You can also look for a model number or designator on the fluorescent tube: if the code F32T8 is printed on the lamp, this is most likely a compatible fluorescent tube specification.

For most customers, we recommend simply swapping out the fluorescent lamp with our T8 LED tube, as this approach provides the easiest method. For further information and instructions on rewiring for ballast bypass, please refer to our install guide / user manual.


Note on Ballast Compatibility: Our T8 lamps are designed to work with almost all T8 fluorescent ballasts. Please see here for a list of ballasts with which we have tested and confirmed compatibility. The T8 LED lamps can also be used without a ballast.

We recommend removing or bypassing T12 fluorescent ballasts for compatibility reasons.
