  • Step dimming to 50 % cuts energy use
  • Rapid start delivers instant light at 0 °F
  • 120–277 V input fits most commercial circuits
  • Runs one or two T5 lamps up to 35 W
  • Optanium electronic design reduces ballast losses

Philips Advance Optanium Ballast

The Philips Advance IOP-2S28-115-SC-SD is an electronic fluorescent dimming ballast designed for T5 lamps. It operates on a universal input voltage of 120 to 277V AC and supports one or two bulbs with a maximum of 35 watts each. The unit uses rapid start technology and provides step dimming via a 0-10V control method.

Installers needing step-dimming T5 control

This ballast suits projects requiring 100 percent, 50 percent, and 0 percent light levels on T5 fluorescent fixtures. It is not for installations that need continuous dimming curves or compatibility with other lamp types such as T8 or compact fluorescent. Buyers who want dimming below 50 percent without stepping should look at other solutions.

Sustained operation at 0 degrees Fahrenheit

The ballast maintains reliable rapid starting down to a minimum starting temperature of 0 degrees Fahrenheit. Under continuous load the Optanium electronic circuitry delivers stable output to the supported lamps without the flicker or delay sometimes seen in magnetic alternatives. The step-dimming function holds each level consistently during extended use.

Questions about this item

What T5 fluorescent lamps and 0-10 V dimmer does this ballast require to operate?

It runs one or two T5 lamps up to 35 W total and is controlled by a 0-10 V step-dimming signal that selects 100 %, 50 % or 0 % light output.

Can the Advance IOP-2S28-115-SC-SD share a 120-277 V circuit with older magnetic ballasts?

Yes, its universal 120-277 V AC input allows it to operate on the same branch circuit as legacy ballasts without voltage conflicts.

How do I verify the step-dimming levels are functioning after installation?

Apply the 0-10 V control signal and confirm the lamps switch cleanly between full output, half output and off at the three defined steps.
