GE 28173 Discharge Bulb

The GE 28173 is a 4W T5 discharge lamp with a miniature bi-pin base. It produces 140 lumens and carries the 5104 WW designation for warm white output. Rated for 7500 hours of life, it is supplied new for low-voltage applications.

Aviation and Low-Voltage Specialists

This lamp suits technicians maintaining aircraft interior or instrument lighting that specifies the 5104 WW code. It also fits automotive or marine fixtures requiring a T5 bi-pin discharge source. Buyers needing a standard mains-voltage bulb or a higher-lumen replacement should look elsewhere.

Miniature Bi-Pin Fixture Integration

The bulb installs directly into sockets accepting a T5 miniature bi-pin base without adapters. Its low-voltage design means the surrounding circuit must provide the correct reduced supply. The compact form factor frees space in tight instrument panels or overhead consoles.

Questions about this item

Does the GE 28173 5104 WW require a specific miniature bi-pin socket to operate?

Yes, this 4W T5 discharge bulb uses a miniature bi-pin base that must match the fixture socket for proper electrical contact.

Will this 140 lumen bulb work in a legacy aircraft panel designed for higher-wattage incandescent lamps?

The 4W discharge design draws less power than traditional lamps; verify the panel's voltage and ballast compatibility before installing.

How can I confirm the GE 28173 is performing correctly after installation?

The bulb should emit a warm white light at its rated 140 lumen output and achieve its 7500 hour rated life under normal operating conditions.
