ADVANCE Electronic CFL Dimming Ballast, 277V Input, Operates 2  CFQ26W/G24Q, CFTR26W/GX24Q Lamps, Analog Dimming 5-100%, Programmed Rapid Start

Advance Mark 10 Powerline Electronic CFL Dimming Ballast (VEZ-2Q26-M2-LD)

The Advance Mark 10 Powerline VEZ-2Q26-M2-LD by Signify is a high-performance electronic dimming ballast engineered to operate two 26-watt 4-pin compact fluorescent (CFL) lamps. Utilizing 2-wire phase-cut dimming technology, it works seamlessly with compatible 277V Mark 10 dimmers without requiring additional control wires, making it perfect for commercial office, conference room, and architectural retrofits. Featuring Programmed Start circuitry, this ballast ensures smooth, continuous dimming while maximizing lamp life during frequent switching cycles.

Core Specifications & Features

• Supported Lamps: Operates (2) 26W 4-pin CFL lamps (such as CFQ26W/G24q or CFTR26W/GX24q).
• Dimming Protocol: Mark 10 Powerline (2-wire phase control). Allows you to dim fixtures using existing power lines without pulling separate 0-10V low-voltage wires.
• Dimming Range: Provides smooth, continuous dimming from 100% down to 3% relative light output.
• Input Voltage: 277V, 60 Hz (Commercial voltage).
• Starting Method: Programmed Start gently preheats lamp cathodes before ignition, drastically increasing lamp lifespan.
• Enclosure & Mounting: Durable metal housing measuring 4.98" Length × 3.00" Width × 1.29" Height.
• Safety & Compliance: UL Listed (Type 1 Outdoor), CSA Certified, Class A Sound Rating, and backed by a 5-year manufacturer warranty.

Electrical Performance Data

Frequently Asked Questions

Can I use this ballast on a standard 120V circuit?

No, the VEZ-2Q26-M2-LD is specifically designed for 277V commercial input voltage only. For a 120V application, you would need the equivalent 120V model (which generally starts with "REZ" instead of "VEZ").

What is the difference between Mark 10 Powerline and Mark 7 0-10V dimming?

Mark 10 Powerline utilizes standard 2-wire phase-cut dimmers, meaning the power and the dimming control are sent over the exact same existing hot and neutral wires. Mark 7 ballasts require you to pull two extra, dedicated low-voltage wires (a separate 0-10V circuit) to carry the dimming signal.

Can I use this ballast to upgrade a standard non-dimming CFL fixture?

Yes. Because this Mark 10 ballast does not require extra control wiring, you can replace a standard 277V ballast with this unit using your existing fixture wiring, provided you also replace the standard wall switch with a compatible 277V Mark 10 dimming switch.
