GE 29503 germicidal T5 fluorescent tube

The GE 29503 is a 39-watt T5 germicidal fluorescent tube measuring 34 inches with a clear finish. It uses a 4-pin G10q base and is rated for an average lifetime of 9000 hours. Supplied as a case of 12 tubes, it is intended for facilities that require ultraviolet-C disinfection in air, water or surface treatment systems.

Fits fixtures with G10q sockets and 34-inch T5

Each tube requires a compatible 4-pin G10q lampholder and a ballast rated for 39-watt T5 operation. The 34-inch length determines the fixture spacing, so existing housings must match this dimension. Using the supplied case of 12 allows maintenance teams to replace all lamps in a multi-tube unit during a single scheduled outage.

Replaces G36T5/4P/SE lamps at end of rated life

The upgrade is warranted when existing tubes have reached or exceeded 9000 hours of operation and UV-C output has fallen below the level required for effective disinfection. It is not suitable for general illumination, visible-light applications or fixtures that accept only 2-pin or different-length tubes.

Questions about this item

How quickly does the 39-watt power draw become the limiting factor when the germicidal tubes run continuously?

At 39 watts each, the power draw is constant from the moment the tubes strike and does not increase with sustained operation.

How much heat and noise do the 39-watt T5 tubes produce during all-day germicidal cycles?

The 39-watt fluorescent tubes emit typical low-level heat and a faint ballast hum; no active cooling is required.

What ballast and fixture must already be in place for the 4-pin G10q base to operate?

A compatible T5 electronic or magnetic ballast wired for a G10q 4-pin base and rated for 39-watt SE-series lamps is required.
