Select the lumen output range of your current fixture to find the best Tfive model for your application. (Keep in mind that in most cases you'll be able to use a Tfive with a lower lumen output without any less in light. This is because the Tfive, unlike tube lights, doesn't lose any light into the fixture.)

To find your fixture's lumen output, do a Google search for your fixture's model number to find spec sheets for that fixture—or contact us for assistance!
