Product Overview

The Advance VEZ-1T42-M2-LD is a Mark 10 Powerline electronic dimming ballast designed for (1) compact fluorescent lamp (CFL) with G24Q or GX24Q bases. It operates on 277V (120-277V capable) with programmed start technology, providing reliable ignition and extended lamp life. The ballast features phase-cut dimming from 100% down to 3% light output when used with a compatible Mark 10 Powerline dimmer.

With a ballast factor of 1.0, the VEZ-1T42-M2-LD delivers full nominal lamp lumens. It achieves >98% power factor and <10% THD, meeting ANSI C82.11 standards and FCC Part 18 Class A EMI limits. The Type 1 Outdoor rating allows installation in damp or outdoor locations when properly enclosed.

Why Choose This Product

• 3% to 100% smooth dimming: Architectural-grade phase-cut dimming for precise light level control with Mark 10 Powerline dimmers.
• Programmed start: Extends lamp life by preheating cathodes – ideal for applications with frequent switching.
• High power factor (>98%): Maximizes energy efficiency and meets utility rebate requirements.
• Low THD (<10%): Minimizes harmonic distortion in building electrical systems.
• Outdoor rated (Type 1 Outdoor): Suitable for damp/wet locations when used in approved fixtures.
• End-of-lamp-life shutdown: Automatically detects failed lamps and shuts down for safety.
• Mark 10 Powerline family: Seamless integration with compatible phase-cut dimming systems.

Dimensions

Applications

• Commercial lighting – offices, retail stores, conference rooms
• Hospitality – lobbies, restaurants, hotel rooms
• Outdoor rated fixtures – signage, canopy lights, building exteriors (with proper enclosure)
• Architectural dimming applications requiring smooth phase-cut control
• Energy retrofit projects – replacing static ballasts with dimming capability

Compatibility & Replacement

Fixture type: This ballast is designed for 1-lamp compact fluorescent fixtures using G24Q (4-pin) or GX24Q bases. Compatible with CFQ26W, CFTR26W, CFTR32W, and CFTR42W lamps.

Dimming compatibility: Mark 10 Powerline ballasts require a compatible phase-cut dimmer (forward or reverse phase). Use with Advance Mark 10 or Mark X Powerline dimmers for optimal performance. The ballast ignites lamps at any dimming level without needing to start at maximum output.

Outdoor use: Type 1 Outdoor rating allows installation in damp/wet locations when used in a UL-listed weatherproof enclosure.

Before ordering, confirm:

• Lamp type: Verify your fixture uses one of the listed CFL lamps (26W–42W, G24Q/GX24Q base).
• Input voltage: Confirm supply voltage is 277V (or 120V – ballast is auto-ranging).
• Dimming system: Ensure your dimmer is Mark 10 Powerline compatible (phase-cut).
• Physical dimensions: Verify fixture has adequate space for 4.98" L x 3.00" W x 1.29" H.
• Temperature rating: Maximum case temperature 158°F (70°C).
• Minimum starting temperature: 50°F (10°C).
