T8 Led Lamps Which Are Not Direct-Wire Compatible (With Ballast) Will Require a T8 Ballast to Operate, So Unless the T12 Ballast in the T12 Fixture Is Replaced...
T8 LED lamps which are not direct-wire compatible (with ballast) will require a T8 ballast to operate, so unless the T12 ballast in the T12 fixture is replaced with a T8 ballast, a non-direct-wire compatible T8 LED lamp will not work in a T12 fixture.
Can I use a T8 LED in a T12 fixture?
In an effort to make LED tube lights compatible with the internal dimensions of most fixtures, you will find that most LED tube lights feature a T8 or 1 inch diameter. They can indeed be used in T12 fixtures.
Can you actually retrofit T12 to LED without changing out the ballast? Actually, yes. But before you make a decision, there are other LED solutions to consider for a high-efficiency lighting option for existing T12s. A lot has changed in just a few years in the lighting industry.
