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.

Instant Start Ballast—Instant-start ballasts turn on immediately. They are the most energy-efficient, but shorten the bulb's life.

Rapid Start Ballast—Rapid-start ballasts have a slight turn-on delay, but are gentler on bulbs than instant-start ballasts so bulbs last longer.

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.
