Need a reliable T12 ballast that won’t flicker or fry under pressure? This one’s built for that.
The E240T12RS120/N runs 1 or 2 T12 lamps using rapid start (RS) technology — ideal for smoother startups in commercial or residential settings. With thermal protection, auto-restart, and a normal ballast factor (0.86–1.00), it’s a solid all-rounder for general lighting.
It’s ICES-005 compliant, CSA efficacy-verified, and operates quietly in sensitive spaces.
✅ You need this if:
-
You’re using 25W–40W T12 lamps and want smooth, low-flicker starts
-
You’re working with a 120V power system
-
You want a ballast that supports one or two lamps
-
You need thermal protection and auto-restrike features
-
You’re working in Canada and require ICES-005 and CAN/CSA C654-14 compliance
❌ You don’t need this if:
-
You’re using T5, T8, or anything not named T12
-
You’re working in high-voltage environments (this one’s 120V only)
-
You need dimmable control or advanced programmability
-
You’re hoping to test it and return it — installed ballasts are final sale
