Frequently Asked Questions
How bright is it?
The listing states 3,000 lumens.
What ballast type does it use?
The listing names Type B. Check that it matches your fixture’s wiring.
Is it dimmable?
Yes, the listing says it is dimmable. Check your dimmer.
Can I install it myself?
Swapping a tube is simple only if the type matches the fixture as the maker says. Any rewiring is electrical work, so use a licensed electrician if you are not experienced.
Note: switch the power off at the breaker and let a tube cool before you change it. Check the tube type against your fixture: a Type A tube is meant to work with the existing ballast, a Type B tube bypasses the ballast and needs the fixture rewired, a Type A+B tube is listed to work either way, and a Type C tube uses an external driver. Rewiring a fixture is electrical work, so use a licensed electrician if you are not experienced. Look for a UL or ETL mark, check whether the fixture is rated for the location, and follow the maker’s instructions. Listings differ; we describe what each maker lists.
