GE 38889 Rapid Start Ballast

This GE Lighting ballast is a rapid-start magnetic unit designed to operate two lamps on a 277-volt, 60 Hz supply. It carries the model number 38889 and the designation GEM232T8RS277. The product is supplied new and intended for interior lighting installations that specify a magnetic rapid-start ballast.

Who this suits and who it does not

It suits electricians and facility managers maintaining or installing fixtures wired for two-lamp rapid-start operation at 277 volts. It is not suitable for single-lamp fixtures, for circuits at other voltages, or for installations that require instant-start or programmed-start ballasts. Buyers needing a ballast for a different lamp count or starting method should select an alternative.

Deciding specification

The defining specification is the rapid-start magnetic design rated for two lamps at 277 volts and 60 Hz. Match this voltage, frequency, lamp quantity and starting method exactly to the fixture requirements before purchasing.

Questions about this item

How do I choose between the different versions of the 38889 ballast?

The 38889 is a single model — GEM232T8RS277 — rated for 277 volts, 60 Hz, rapid start magnetic operation, and two lamps; no alternative versions are offered.

What does the 277 volt rating mean once the ballast is installed in a fixture?

It means the ballast is designed to operate on a 277 volt supply at 60 Hz, delivering rapid start ignition for two T8 lamps in compatible fixtures.

What interface or standard does the rapid start magnetic ballast use, and what does that cap in practice?

It uses a rapid start magnetic design for two lamps on a 277 volt, 60 Hz circuit; the magnetic topology limits it to that voltage, frequency and lamp count.
