Frequently Asked Questions
How does this quiz work?
Select your preference on each question—how many ballasts, lamp type, and any special needs. We’ll instantly show your best match based on 8,386+ Amazon reviews and no scrolling required.
What’s the difference between T12 and T8 lamps?
T12 lamps measure 1.5 inches in diameter and are older and less energy-efficient. T8 lamps are 1 inch wide and use about 40% less electricity. Most modern fixtures take T8 tubes, but many older homes still have T12—check your existing bulb.
Why would I buy a 10-pack ballast?
If you’re relamping a whole building or managing maintenance for a commercial space, buying the Robertson 10-pack lowers the per-ballast price to $12.95—roughly less than the single unit. It’s the clear winner for bulk jobs.
Should I replace my ballast with an LED driver instead?
If you’re ready to convert to LED tubes, you’ll bypass the ballast entirely and do a direct-wire installation. For existing fluorescent fixtures, though, sticking with a ballast is simpler and more accessible for DIYers.
How often do ballasts fail?
Fluorescent ballasts typically last 5–15 years. Signs of failure include flickering, buzzing, or lamps that take several tries to turn on. All our picks come from highly-rated brands known for reliability.
Do I need to be an electrician to replace a ballast?
A competent DIYer can replace a ballast with basic tools, provided you follow wiring diagrams and turn off the power. The models we recommend often earn praise for easy installation, though wire nuts are rarely included.
