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.
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!
