Retrofit Socket Kits for Tubular Light Bulbs

Revive your fluorescent strip lights. These sockets replace aging ones and eliminate the need for ballasts. Instead, they power the bulb from one end. Use them with ballast bypass LED bulbs. They’re an economical alternative to replacing the ballast and outfitting your light with socket-ready LED bulbs.
Remove the old sockets and ballast, connect the spring-clamp terminals to your power supply, and bend the bracket tabs to fit the width of your fixture housing.
