LED Tubes and Ballasts

This understanding is crucial for selecting the right type of LED tube and ensuring compatibility with existing lighting fixtures.

What are Ballasts?

Ballasts regulate the current in fluorescent lighting systems as electrical devices, ensuring that the lights receive the correct amount of power needed to start and operate efficiently. There are primarily two types of ballasts: magnetic and electronic.
