Electronic 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 ballasts turn on immediately. They are the most energy-efficient, but shorten the bulb's life.
Rapid-start ballasts have a slight turn-on delay, but are gentler on bulbs than instant-start ballasts so bulbs last longer.

Magnetic Ballasts for Tubular Fluorescent Light Bulbs
These ballasts are often found in older installations. Ballasts that can operate multiple bulbs may have more wires than you need. Cover unused wires with a wire nut. Ballasts take several seconds to turn on and require a starter.
