Advance Centium ICN-2S28-T Electronic Fluorescent Ballast Guide
Quick Answer: The Advance Centium ICN-2S28-T (Signify / Philips Advance) is a commercial-grade high-efficiency 2-lamp electronic fluorescent ballast engineered to operate 1 or 2 F28T5 linear lamps (as well as 25W energy-saving F28T5/ES, F35T5, F14T5, and F21T5 lamps) on universal 120–277V line voltage. Featuring Programmed Start ignition, IntelliVolt auto-voltage sensing, a normal 1.03 Ballast Factor, and an ultra-compact T-Can metal enclosure, it is designed for maximum lamp cathode longevity and space-saving integration in commercial troffers, architectural pendants, and cove lighting fixtures.
Advance Centium ICN-2S28-T Overview & Key Features
The Advance Centium ICN-2S28-T ballast provides reliable, commercial-grade electrical efficiency, versatile multi-lamp compatibility, and extended cathode life across low-profile architectural fixtures:
- Programmed Start Technology: Gently preheats lamp cathodes before striking the arc, minimizing cathode degradation and eliminating end-blackening in occupancy sensor and frequently switched environments.
- IntelliVolt Universal Voltage: Automatically operates across AC line inputs from 120V to 277V at 50/60 Hz without manual tap changes or rewiring.
- Compact T-Can Enclosure: Slim, space-saving metal housing designed to fit seamlessly into shallow troffer wireways, narrow cove channels, and slim architectural linear profiles.
- Multi-Lamp Versatility: Engineered to power standard 28W linear T5 lamps (F28T5) as well as energy-saving 25W T5 lamps, F35T5, F21T5, and F14T5 lamps.
- High Electrical Quality: Commercial-grade power quality featuring a high power factor (>0.98) and Total Harmonic Distortion (THD) under 10%.

Installation & Wiring Guidelines
- Power Disconnect: Always shut off main AC electrical 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 case label. Programmed start circuitry requires dedicated pairs of leads routed to each rapid/programmed start lamp socket.
- Enclosure Grounding & Thermal Dissipation: Securely fasten the metal T-can housing to the grounded metal luminaire body to ensure proper thermal conduction and ground continuity.
Frequently Asked Questions
What does "ICN-2S28-T" stand for in Advance's catalog?
"I" designates IntelliVolt (120–277V), "CN" represents the Centium commercial series, "2" indicates 2-lamp maximum capacity, "S" stands for Programmed Start, "28" indicates 28W standard linear T5 lamps, and "T" denotes the low-profile T-Can housing style.
What is the difference between ICN-2S28-T and ICN-2S24-T?
The ICN-2S28-T is engineered specifically for standard-output 28W linear T5 lamps (F28T5), whereas the ICN-2S24-T is designed for high-output 24W linear T5/HO lamps (F24T5/HO) and twin-tube compact fluorescents.
Can the Advance Centium ICN-2S28-T operate a single lamp?
Yes. The ICN-2S28-T is UL listed and engineered to operate either 1 or 2 linear T5 fluorescent lamps safely according to the approved wiring diagram on the ballast label.
