Ballast and Electrical Component Changes
What are ballasts
Within the last 50 years, the lighting industry has changed a lot. Possibly none of the lighting fixtures and hardware made in the current times now use the ballasts. The old fluorescent lamps that still use the ballast are getting low and low in manufactured numbers.
This is a very relevant, in-time question to ask that what are ballasts.
What is the functions of a ballast
A ballast has two functions. During the lamp start up, it provides the sufficient voltage to the lamp to start. During the running time, it regulates and provides just enough voltage to draw the right current. Without ballast, the lamp will draw enormous amounts of current and will fail rapidly. Each lamp has its own ballast in a fluorescent lighting system.
