Commercial fluorescent ballast

The Philips Advance IOPA-4P32-LW-N is an electronic ballast designed for commercial fluorescent lighting systems. It operates three or four T8 lamps at 120 to 277 volts AC with instant start operation. The unit weighs 0.85 pounds and supports lamp wattages of 17, 25, 28, 32, and 40 watts. It is not suitable for dimming applications or residential fixtures requiring rapid start.

Magnetic ballast replacement

This ballast replaces older magnetic units in three or four lamp T8 fixtures, eliminating flicker and reducing energy consumption. The upgrade is worthwhile when existing ballasts fail or when converting fixtures to instant start operation. It does not support dimming controls, so installations requiring light level adjustment need a different model. The minimum starting temperature is -20 degrees F.

Sustained operation characteristics

Under continuous load the ballast maintains stable lamp current across the 120 to 277 volt input range. Instant start delivers full light output immediately without preheat delay. The 94 watt maximum input handles four 32 watt lamps or mixed wattage combinations up to the rated limit. No dimming circuitry means constant output during extended run times.

Questions about this item

What are the mounting dimensions and weight of the IOPA-4P32-LW-N ballast?

The unit weighs 0.85 lb and uses standard Philips Advance mounting holes; check the case label for centre-to-centre spacing before drilling.

How do I wire the instant-start ballast for 120 to 277 V input and avoid the common mistake?

Connect line and neutral to the black and white leads; the error is reversing the red and blue lamp leads — follow the diagram on the label for 3- or 4-lamp T8 wiring.

Which T8 lamp wattages can I use later when relamping this ballast?

The ballast is rated for 17 W, 25 W, 28 W, 32 W and 40 W T8 lamps; choose any combination that keeps total load within the 94 W rating.
