Due to efficiency legislation, magnetic fluorescent sign ballasts have gone the way of the dinosaur. As a result, businesses have moved on to more efficient electronic sign ballasts. But electrical contractors discovered a particular challenge in this: they weren't wired the same way.
So hours were spent rewiring entire signs in order to accept these newer ballasts.
Enter the new generation of electronic fluorescent sign ballasts: Universal saw and responded to this challenge by developing new electronic sign ballasts that are wired the same way as magnetic sign ballasts, so now it's easier than ever to make the switch to efficiency.
This doesn't make these the only electronic sign ballasts available. But if they meet the needs of your lighting project, they may be a great way to save time backed by a quality brand.
