Before you run out and buy your T8 or T12 fluorescent lights, you should consider these two things:
No, T8 LED tubes do not require a starter. However, traditional T8 fluorescent tubes often require a starter to initiate current flow. The role of a starter in fluorescent tubes is to send a surge of high voltage to the tube, causing it to illuminate.
T8 LED tubes are designed to work without a starter. They are engineered in such a way that they can either be compatible with existing fluorescent ballasts or they can be directly wired to the electrical supply.
The method of installation for these LED tubes depends on the type of tube being used. It is important to carefully read the manufacturer’s instructions to identify the specific installation requirements of your T8 LED tubes.

Yes, a T12 ballast can be replaced with a T8 ballast. However, it is important to note that T12 and T8 refer to the diameter of the lamps:
Because of this difference in size, if you are replacing a T12 ballast with a T8 ballast, you will also need to replace your T12 lamps with T8 lamps. In addition to replacing the ballast, you will also need to remove or bypass the starter if one is present, as T8 LED tubes don’t require it.
Keep in mind, using a T12 lamp in a T8 ballast can easily cause the ballast to fail due to the size difference, and using T8 lamps in T12 ballasts could lead to shortened tube lifespan due to the higher voltage output of the ballast.
