Description
ADVANCE Metal Halide F-Can Ballast, 175W/150W (ANSI M57/M107), 120V/277V Input, Type CWA, Probe Start
Advance 150W Metal Halide F-Can Magnetic Ballast (72C5581-NP)
The Advance 72C5581 (commonly ordered as 72C5581-NP) by Signify is an enclosed fluorescent-style “F-Can” magnetic ballast designed to reliably operate one 175W or 150-watt pulse-start metal halide lamp (ANSI M102). Engineered with a dual-voltage 120/277V HX-HPF (High Reactance High Power Factor) circuit, this fully potted ballast contains the core, coil, dry capacitor, and ignitor encased in sound-dampening, thermally conductive resin to ensure whisper-quiet operation in noise-sensitive indoor retail, recessed commercial downlight, and architectural spaces.
Key Features & Performance Benefits
- Enclosed “F-Can” Housing: Houses the core, coil, capacitor, and ignitor completely sealed in an insulating asphalt resin within a heavy-gauge steel enclosure to minimize magnetic hum and mechanical vibration.
- Ultra-Quiet Operation: The fully potted design delivers superior sound dampening compared to open core-and-coil assemblies, making it the ideal solution for interior downlights, lobbies, shopping malls, and classrooms.
- HX-HPF Circuitry: High Reactance High Power Factor design ensures reliable arc ignition, high electrical efficiency (≥ 90% power factor), and minimal line-current loss.
- Dual-Voltage Primary Taps: Factory-configured with dedicated lead wires for both 120V and 277V 60 Hz service connections.
- Safety & Thermal Protection: UL Listed (Class P, Type 1 Outdoor), CSA Certified, features built-in automatic-resetting thermal protection, and utilizes non-PCB internal components.

Frequently Asked Questions
What does "72C5581" stand for in Advance's catalog?
"72C" designates an indoor F-Can enclosed HID ballast line, "55" indicates 150W or 175W lamp capacity, "81" specifies the ANSI M102 pulse-start circuit with 120/277V dual-voltage taps, and "-NP" indicates a Non-PCB internal capacitor configuration.
What is the primary advantage of an F-Can ballast over an open Core & Coil kit?
F-Can ballasts encase the transformer, capacitor, and pulse ignitor inside a sealed steel housing filled with thermally conductive potting resin. This dampens magnetic vibration, substantially quiets audible hum, and provides built-in thermal protection for indoor fixtures.
Does this ballast require an external ignitor or capacitor during installation?
No. Unlike open core-and-coil replacement kits, the capacitor is already wired and permanently potted inside the sealed F-Can enclosure, requiring only direct line and lamp socket connections.
