Electronic Light Ballasts for Tubular Fluorescent Light Bulbs
 |
In addition to being more energy-efficient than magnetic ballasts, these electronic ballasts are lighter and quieter. Ballasts that can operate multiple bulbs may have more wires than you need. Cover unused wires with a wire nut.
Programmed Start Ballast—Programmed-start ballasts provide the longest bulb life, but they take longer than instant- and rapid-start ballasts to turn on. They are often used with motion-sensing light controls.
