Is it compatible with my fixture?

Our T8 LED tube is designed to directly replace 4-ft T8 fluorescent lamps, and can be directly installed into an existing 4-ft fluorescent fixture without having to open the fixture housing and rewiring the connections.

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. Below are the basic requirements for compatibility:

• 4-ft (48") in length
• T8 style tube (1" tube diameter)

You can also look for a model number or designator on the fluorescent tube. The most common designation is F32T8, which is a compatible fluorescent tube specification.

For most customers, we recommend this approach for ease of installation. For further information and instructions on rewiring for ballast bypass, please refer to our install guide / user manual.

Please contact us with any further or specific questions about compatibility.

What if I don't have a fluorescent fixture?

We have tested and confirmed compatibility with the following fixtures which can be purchased at your local hardware store:

• Metalux Model No: SSF232R (2-lamp, ceiling mount style, hard-wired)
