How to Direct-Wire a Fixture for Single-Ended LED Lamps

Energy Focus Blog


Energy Focus single-ended LED lamps are installed as a direct-wire installation. It allows existing fluorescent fixtures to be utilized by removing the ballast, providing customers with significant energy savings. Single-ended LED tubes do not depend on any ballast to function normally, minimizing points of failure and requiring less maintenance. Additionally, Energy Focus offers a 10-year pin-to-pin warranty meaning you will have fewer costs of replacing bulbs and less time focusing on lighting maintenance.

You can view our retrofit installation video below and follow along with our easy laid-out steps with pictures!
