All of these fluorescent tube lights are available in different lengths and wattages. You are likely to see the T8 or T12 in a laundry room, kitchen, or garage. They commonly have magnetic or electronic ballasts, which help limit the amount of current in an electrical circuit. Typically,...
Fluorescent Lighting Guide for Indoors Fluorescent bulbs or lamps produce light by energizing the phosphor coating on the inside of a glass envelope. A device called the ballast regulates the power needed to start the lamp and keep it going. Older magnetic ballasts caused humming and flickering,...
