  • Thinklux Universal Fit LED fluorescent replacement tube lights allow for the first time the ability to upgrade any T8 or T12 fixture to LED technology with a simple plug and play install. Additionally, the Thinklux Universal Fit will dim with existing T8 electronic dimming ballasts. A perfect choice for anyone who wants a quick and easy retrofit with no rewiring or for fixtures where the ballast is not easy to access. The first universal tube to be DLC qualified, this product is rebate ready with power providers using the DLC qualification as a basis for rebate.

    Install Notes:
    Must be installed with a ballast. Cannot be used as a direct wire or ballast bypass tube light. In other words, if your ballast is no longer functioning, LED tube will not function either. Due to the wide variety of ballasts on the market, including those no longer manufactured, ballast compatibility is not guaranteed. See downloads section for list of tested ballasts. Dimming function requires existing T8 dimmable ballast with dimmer to be installed.
