Electronic Ballast for T12 Lamps

The Philips ADVANCE RELB-2S40-N electronic ballast operates one or two fluorescent lamps at 120 V AC. It supports T12 and T12U bulb types with maximum ratings of 30 W, 34 W, or 40 W per lamp. The unit provides rapid start operation and a minimum starting temperature of 50 °F.

Suits Dual-Lamp Fixtures

This ballast fits installations needing a single device to drive two lamps without dimming capability. It is not suitable for fixtures that require dimming control or for lamps exceeding the 40 W maximum per bulb. Buyers needing dimming functions or different voltage inputs should consider other options.

Rapid Start at 120 V Input

The decisive specification is the rapid start type combined with a 120 V AC input voltage. Verify that the fixture wiring and lamp specifications match this start method and voltage before purchase.

Questions about this item

How can I confirm the ballast is working correctly after installation?

The lamps should start rapidly and run without flickering at 120 V input; both supported lamps must light evenly.

What comes in the box and is anything else required?

The package contains the 72 W electronic ballast only; compatible T12 or T12U lamps rated 30 W, 34 W or 40 W must be purchased separately.

Which lamp wattage should I select for this ballast?

Choose T12 or T12U lamps rated 30 W, 34 W or 40 W; the ballast supports one or two lamps within that range.
