Philips Advance Centium ICN2S28N35I 2-Lamp T5 Electronic Ballast – 120-277V IntelliVolt | Programmed Start | F28T5 / F21T5 / F14T5 / F35T5 | EOL Protection

The Philips Advance Centium ICN2S28N35I is a 1-or-2-lamp programmed start electronic ballast designed for T5 fluorescent lamps on universal 120–277V IntelliVolt circuits. Programmed start circuitry extends lamp life in frequent-switching environments — including occupancy sensor and motion detector-controlled circuits — while auto-restrike capability and End-of-Life (EOL) protection deliver safe, low-maintenance operation across commercial and institutional T5 fixtures.

Product Overview

The Philips Advance Centium ICN2S28N35I is engineered for T5 fluorescent fixture applications where switching frequency, lamp life, and installation flexibility are primary concerns. Programmed start circuitry preheats lamp cathodes before ignition — the key technical factor that extends T5 lamp life in applications controlled by occupancy sensors, motion detectors, or daylight harvesting systems that cycle lamps multiple times per day.

IntelliVolt 120–277V universal input eliminates voltage-specific ordering across multi-circuit facilities. The ballast handles 1 or 2 T5 lamps from 14W through 35W, covering the full range of standard T5 linear fluorescent lamps in a single SKU. Auto-restrike capability allows the ballast to attempt lamp reignition after a lamp extinguishes without cycling the circuit breaker — reducing nuisance service calls in facilities where lamps are subject to vibration or intermittent failure.

EOL protection circuitry monitors the lamp throughout its service life and safely removes power when the lamp reaches end of life — preventing overheating, flickering, and potential fixture damage. The low-profile 9.5 x 1.3 x 1.0-inch housing is among the slimmest T5 ballast footprints available, fitting narrow-channel T5 fixtures that cannot accommodate standard-height ballasts.

Why Choose This Product

• Programmed start for occupancy sensor compatibility: Preheats cathodes before ignition — the correct choice for fixtures controlled by occupancy sensors, motion detectors, or any circuit with frequent switching cycles. Extends T5 lamp life significantly compared to instant start designs in these applications.
• IntelliVolt 120–277V universal input: Covers all standard North American commercial voltages on a single part number — no voltage-specific ordering for mixed-circuit facilities.
• Full T5 lamp wattage range (14W–35W): One ballast operates F14T5, F21T5, F28T5, and F35T5 lamps — simplifies inventory for facilities with multiple T5 fixture types.
• Auto-restrike capability: Automatically attempts to reignite a lamp after it extinguishes — reduces service calls from nuisance lamp failures without requiring manual power cycling.
• EOL protection with safe power removal: Cuts power to the lamp circuit at end of lamp life — prevents overheating, eliminates flickering, and protects the fixture from damage caused by a failing lamp.
• Ultra-low-profile housing (9.5 x 1.3 x 1.0 in): Fits narrow T5 fixture channels where standard-height ballasts cannot be installed — expands retrofit compatibility.
• RoHS compliant: Meets hazardous substance restrictions for commercial and institutional procurement.

Applications

The Philips Advance Centium ICN2S28N35I is suited for T5 fluorescent fixture applications in commercial and institutional environments — especially where switching frequency or lamp longevity are critical:

• Occupancy sensor and motion detector-controlled fixtures – Programmed start is the specification-required start method for fixtures that switch frequently. Protects T5 lamp cathodes and extends rated lamp life in high-cycle applications.
• Office buildings and commercial interiors – T5 troffer, linear pendant, and under-cabinet fixtures on 120V or 277V circuits requiring quiet, efficient ballast operation.
• Retail and display lighting – T5 linear fixtures in display cases, shelving, and accent lighting where the ultra-slim 1.0-inch housing fits narrow fixture channels.
• Schools and educational facilities – Classroom and corridor T5 fixtures with occupancy-sensor controls benefit directly from programmed start lamp life extension.
• Healthcare facilities – T5 fixtures in patient rooms, corridors, and clinical spaces with frequent switching or dimming control systems.
• Energy management and lighting control systems – Auto-restrike and EOL protection reduce maintenance calls in facilities with centralized lighting control and remote monitoring.

Replacing Your Current T5 Fluorescent Ballast?

Confirm the following before ordering to ensure a compatible installation:

• Lamp type: This ballast operates T5 linear lamps only — F14T5, F21T5, F28T5, and F35T5. It is not compatible with T5HO (High Output) lamps. Verify your lamp code before ordering.
• Lamp count: Operates 1 or 2 lamps. Confirm your fixture lamp count before ordering.
• Start method — programmed start: This is a programmed start ballast. It requires T5 lamps with compatible cathode pin configurations. For occupancy sensor or frequent-switching applications, programmed start is the recommended specification.
• Circuit voltage: IntelliVolt 120–277V covers all standard North American commercial voltages, 50/60Hz.
• Physical fit: Housing is 9.5 x 1.3 x 1.0 inches — one of the slimmest T5 ballast profiles available. Verify your fixture ballast channel accommodates this footprint.
• Not for T5HO: Do not use this ballast with T5HO (High Output) lamps such as F54T5/HO or F39T5/HO. Those lamps require a T5HO-rated ballast.
