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.

Ballasts for Metal Halide Light Bulbs
Probe-start ballasts are often found in older installations.
Pulse-start ballasts turn on faster than probe start. Some include a starter, which increases bulb life.
