Description
ADVANCE Electronic Fluorescent Ballast, Universal 120V-277V Input, 1 or 2 F28T5, F21T5, F28T5/ES, (2) F14T5, (1) F35T5 Lamps, Programmed Start
Advance Optanium IOP-2S28-95-SC Electronic Fluorescent Ballast Guide
Quick Answer: The Advance Optanium IOP-2S28-95-SC (Signify / Philips Advance) is a high-efficiency 2-lamp electronic fluorescent ballast engineered to operate 1 or 2 F28T5 linear lamps (as well as 25W energy-saving F28T5/ES, F21T5, and F14T5 lamps) on universal 120–277V line voltage. Featuring Programmed Start ignition, IntelliVolt auto-voltage sensing, a normal 0.95 Ballast Factor, and a low-profile Small Can (SC) enclosure, it provides maximum energy efficiency and lamp cathode protection for commercial linear T5 luminaires.
Advance Optanium IOP-2S28-95-SC Overview & Key Features
The Advance Optanium IOP-2S28-95-SC commercial ballast delivers energy-efficient performance and extended lamp life across architectural linear fixtures, cove lighting, and commercial troffers:
- Programmed Start Technology: Gently preheats lamp cathodes prior to arc initiation, significantly reducing filament wear and extending lamp lifespan in installations with occupancy sensors and frequent switching cycles.
- IntelliVolt Universal Voltage: Automatically senses and operates across input voltages from 120V to 277V AC at 50/60 Hz.
- Normal Ballast Factor (0.95 BF): Delivers optimal standard light output and energy consumption engineered specifically for 28W T5 fluorescent systems.
- Small Can (SC) Low-Profile Enclosure: Compact metal housing designed to fit easily inside narrow linear T5 fixture channels and tight architectural wireways.
- High Electrical Quality: Commercial-grade power quality with high power factor (>0.98) and Total Harmonic Distortion (THD) under 10%.

Installation & Wiring Guidelines
- Power Disconnect: Always turn off main AC power at the circuit breaker panel prior to servicing or installing the ballast.
- Programmed Start Socket Wiring: Follow the wiring diagram printed on the ballast housing carefully. Programmed start circuitry requires dedicated lead pairs connected to each rapid/programmed start lamp socket.
- Enclosure Grounding: Securely fasten the metal Small Can case to the grounded luminaire housing to ensure proper equipment ground and thermal dissipation.
Frequently Asked Questions
What does "IOP-2S28-95-SC" stand for in Advance's catalog?
"IOP" designates the Optanium series, "2" indicates 2-lamp maximum capacity, "S" stands for Programmed Start, "28" represents 28W T5 lamps, "95" indicates the 0.95 Ballast Factor, and "SC" denotes the Small Can enclosure style.
What is the difference between IOP-2S28-95-SC and IOP-2S28-95-SC-SD?
The standard IOP-2S28-95-SC is a fixed-output ballast operating lamps at full output, whereas the IOP-2S28-95-SC-SD model features Step-Dim (SD) dual-switched bi-level dimming (100% / 50% / Off).
Can the Advance IOP-2S28-95-SC operate a single lamp?
Yes. The IOP-2S28-95-SC is UL listed and engineered to operate either 1 or 2 linear T5 fluorescent lamps safely.
