Bulk 40-pack compact fluorescent

The GE Lighting 75399 comes as a case of 40 single-tube compact fluorescent lamps. Each 25-watt bulb produces 2600 lumens at a 3000K colour temperature. The 2G11 four-pin base fits compatible commercial fixtures. Rated life is 20,000 hours per lamp.

2G11 base and instant-start ballast compatibility

The four-pin 2G11 base is designed for instant-start electronic ballasts marked for 800 series or 830 lamps. No separate starter or preheat circuit is required. The Watt Miser designation indicates reduced power draw compared with standard 40-watt equivalents. Bulbs measure 21.5 inches end to end.

General-area lighting with 20,000-hour rating

The 3000K output suits offices, retail spaces and corridors where warm white light is preferred. A single case supplies 40 lamps for multi-fixture relamping projects. Not suited for dimming circuits, enclosed fixtures rated for lower wattage, or applications needing higher lumen output per lamp.

Questions about this item

How often will the 2G11 base lamps need replacing at 20,000 hours life?

Each lamp is rated for 20,000 hours, so replacement timing depends on daily run hours; at twelve hours per day expect roughly four and a half years before the rated end of life.

What limits continuous operation of the 25 watt T5 tubes?

The 25 watt power draw and 2,600 lumen output remain stable until the 20,000 hour rating, after which light depreciation and eventual cathode wear become the limiting factors.

How much heat and noise do the 21.5 inch Biax tubes produce running all day?

The 25 watt fluorescent tubes run silently and emit modest heat typical of compact fluorescents; no fan or moving parts are present, so audible noise is negligible during extended use.
