Item #: 70744
The FS-4 starter is for 30w - 40w preheat fluorescent lamps. It has a turn and lock base that fits any starter base socket. The FS4 starter is cULus approved. the FS4 starter works with all 120v fluorescent preheat ballasts for 30w and 40w lamps.
Item was great, did exactly what it was supposed to do. Replaced a bad unit in my fixture, easy and quick to install!
Would highly recommend this company! Received my order in 2 days and pricing was very responsible. Thanks!
