GE 23300 Airfield Bulb Case

The GE 23300 is a case of 24 incandescent airfield light bulbs rated at 6.6 amps and 31 volts. Each T14 tubular bulb uses a medium prefocus P28s base and produces 4220 lumens at a 3200K colour temperature. The 204 watt lamps are designed for airport and airfield lighting systems requiring constant-current series circuits.

Replaces Legacy T14 Series Lamps

These bulbs directly replace existing T14 medium prefocus lamps in airfield approach, threshold and runway edge fixtures. The jump is worth it when a full circuit relamp is scheduled to maintain uniform photometric output across the lighting array. They are not suited for fixtures requiring a different base type, voltage or wattage rating.

Sustained Output on Constant-Current Circuits

On a 6.6 A series circuit the filament operates at its design current, delivering steady 4220 lumen output for the rated service life. The clear tubular envelope maintains consistent light distribution during continuous dusk-to-dawn operation. They are not designed for variable-voltage dimming or short-cycling applications that accelerate filament degradation.

Questions about this item

What base type does the GE 23300 use for mounting in airfield fixtures?

The bulb uses a Medium Prefocus P28s base, which locks into the socket with a twist-and-seat action rather than a simple screw-in.

How do you install the T14 tubular bulb without damaging the filament?

Hold the glass envelope, not the base pins, align the prefocus tabs with the socket slots, push straight in until seated, then give a quarter-turn clockwise to lock.

When should the 204-watt 6.6-amp lamps in this 24-count case be replaced?

Replace them when light output drops below the required 4220 lumen level or at the airfield maintenance interval specified for 3200 K incandescent airfield lamps.
