GE Lighting 68192 GEM220TS120/2-DIY Magnetic Ballast 120V 60Hz 2-Lamp Pack of 4

SKU CH-N33P-G250J

Pack of four 120 V 60 Hz magnetic ballasts, each running two 20 W, 15 W or 15 W T12 or T8 fluorescent lamps

  • Ready for F20T12, F15T12 or F15T8 lamp pairs
  • 120 V 60 Hz input matches standard mains supply
  • Four ballasts included for multi-fixture projects
  • Low 0.50 A draw on 20 W lamps saves energy
  • GE brand trusted for reliable magnetic ballast performance

Application & Audience

This pack contains four GE magnetic ballasts, model GEM220TS120/2-DIY, each rated for two lamps at 120 volts and 60 Hz. They are intended for maintenance crews and DIYers replacing existing magnetic ballasts in linear fluorescent fixtures. Buyers converting to LED tubes that require ballast bypass will not use these units.

Build & Connections

Each ballast supports three two-lamp configurations: two F20T12 lamps, two F15T12 lamps, or two F15T8 lamps. Input current measures 0.50 amps with F20T12 lamps and 0.52 amps with either F15T12 or F15T8 lamps. The magnetic core-and-coil construction fits standard fluorescent troffer or strip housings using the same mounting centres as the original equipment.

Thermals, Noise & Power

Magnetic ballasts operate at line frequency, so a low audible hum is normal during use. The case temperature rises under load but remains within the design limits for enclosed fixtures. Power draw follows the lamp wattage: approximately 20 watts per lamp for F20T12 and 15 watts per lamp for the F15 types, plus ballast losses.

Questions about this item

What does the 120V 60Hz rating mean for the GEM220TS120/2-DIY ballast?

The ballast operates on standard 120 volt household power at 60 Hz frequency, drawing either 0.50 A with two F20T12 lamps or 0.52 A with two F15T12 or F15T8 lamps.

What wiring and mounting does each ballast need for a two-lamp setup?

Each unit is a magnetic ballast designed for two lamps in series; it requires line and neutral supply wires plus two lamp leads per tube, and mounts via its metal case tabs to a fluorescent fixture channel.

How do you install the 68192 ballast and what is the common wiring mistake?

Turn off power, remove the old ballast, connect the black and white supply wires to the ballast leads, then attach the paired red and blue leads to the lampholders; the frequent error is mixing the common red lead with the individual blue leads, causing one lamp to stay dark.
