Advance Centium ICN-4S54-90C-2LS-G Electronic Fluorescent Ballast Guide
Quick Answer: The Advance Centium ICN-4S54-90C-2LS-G (Signify / Philips Advance) is a high-efficiency 4-lamp commercial electronic fluorescent ballast engineered to operate 1 to 4 F54T5/HO linear lamps (as well as 49W energy-saving F54T5/HO/ES, FT55W/2G11 twin-tube, and FT50W lamps) across universal 120–277V line voltage. Featuring Programmed Start ignition, a 90°C maximum case rating for high-ambient applications, 2-lamp switching capability (2LS), a 1.0 Ballast Factor, and a heavy-duty G-can enclosure, it is the industry standard for commercial and industrial high-bay luminaires.
Advance Centium ICN-4S54-90C-2LS-G Overview & Key Features
The Advance Centium ICN-4S54-90C-2LS-G commercial ballast delivers robust electrical performance, high-ambient thermal tolerance, and flexible light control across industrial warehouses, high-bay luminaires, and commercial interiors:
- 2-Lamp Independent Switching (2LS): Built with dual internal circuitry allowing separate line-voltage switching of two pairs of lamps (2 on / 4 on) for stepped energy conservation.
- High-Ambient 90°C Thermal Rating: Engineered with premium thermal components rated up to 90°C case temperature (Tc), making it ideal for hot ceiling plenums and enclosed industrial high-bay fixtures.
- Programmed Start Ignition: Precisely heats lamp filaments prior to ignition, extending cathode life in applications with occupancy sensors and frequent switching cycles.
- IntelliVolt Universal Voltage: Automatically operates across AC input line voltages from 120V to 277V at 50/60 Hz without rewiring taps.
- High Electrical Performance: Delivers a 1.00 Ballast Factor with high power factor (>0.98) and low Total Harmonic Distortion (THD <10%).
- Robust G-Can Metal Housing: Heavy-duty commercial metal enclosure designed for rapid heat sinking and mounting inside standard high-bay channels.

Installation & Wiring Guidelines
- Power Disconnect: Always shut off main AC electrical power at the circuit breaker panel prior to servicing or installing the ballast.
- 2LS Dual-Circuit Switching: For bi-level switching (2 lamps / 4 lamps), connect Line 1 (Black) and Line 2 (Black/White) to separate wall switches or dual-relay occupancy controls, with White connected to Neutral. For single-switch full 4-lamp operation, tie Line 1 and Line 2 together to the switched hot feed.
- Programmed Start Socket Wiring: Follow the wiring diagram printed on the ballast housing label. Programmed start circuitry requires dedicated pairs of leads routed to each rapid/programmed start lamp holder.
- Enclosure Grounding & Thermal Dissipation: Securely fasten the metal G-can housing to the grounded metal fixture enclosure to ensure reliable electrical ground and direct heat dissipation.
Frequently Asked Questions
What does "ICN-4S54-90C-2LS-G" stand for in Advance's catalog?
"I" designates IntelliVolt (120–277V), "CN" represents the Centium commercial series, "4" indicates 4-lamp maximum capacity, "S" stands for Programmed Start, "54" indicates 54W T5/HO lamps, "90C" denotes the 90°C high-ambient temperature rating, "2LS" signifies 2-Lamp Switching capability, and "G" denotes the G-can housing style.
How does 2-Lamp Switching (2LS) work on this ballast?
The ballast includes two independent AC line input leads (Line 1 and Line 2). When connected to two separate wall switches or relays, users can energize one lead to illuminate 2 lamps (50% power) or both leads to illuminate all 4 lamps (100% power) without needing a dedicated dimming controller.
Can this ballast operate 1, 2, or 3 lamps instead of 4?
Yes. The ICN-4S54-90C-2LS-G is multi-lamp rated and UL listed to operate 1, 2, 3, or 4 F54T5/HO lamps safely according to the approved wiring diagrams on the product label.
Replacement for ICN-4S54-90C-2LS. The ICN-4S54-90C-2LS-G is shorter (16.7" vs 24"), wider and potted.
