Overview
The Solium Sense-a-Volt 32750 is an electronic CFL ballast engineered for facility and industrial lighting systems requiring flexible dual-voltage operation. Designed to drive 26/32W compact fluorescent lamps with a 4-pin socket, this ballast accepts either 120V or 277V input at 50/60 Hz, eliminating the need to stock separate ballast models for different facility zones. The compact form factor and proven electronic construction make it well-suited for retrofit installations in existing fixtures where space constraints and voltage flexibility are priorities.
Key Features
- Dual voltage input: 120V and 277V operation on a single unit reduces parts inventory
- 4-pin CFL socket: Compatible with standard G24 compact fluorescent lamps rated 26W or 32W
- Electronic ballast design: Provides stable lamp current and extended lamp life compared to core-and-coil alternatives
- Sense-a-Volt technology: Built-in voltage detection protects lamps from input voltage extremes
- Compact enclosure: Fits into standard fixture mounting spaces for straightforward substitution
- 50/60 Hz operation: Compatible with standard North American electrical infrastructure

Typical Applications
- Commercial office and facility lighting upgrades where mixed voltage distribution exists
- Industrial warehouse and manufacturing area fixture retrofits
- Multi-facility operations requiring a single standardized ballast across 120V and 277V zones
- Maintenance spare inventory and cost-effective lighting replacements
- Energy-efficient facility lighting conversions from older magnetic ballasts
Compatibility & Replacements
The Solium 32750 is designed as a direct replacement for existing 26/32W, 4-pin compact fluorescent ballasts in compatible fixtures. When planning a replacement, verify the following with your fixture documentation:
- Lamp wattage matches 26W or 32W rating
- Socket pin configuration is 4-pin (G24)
- Input voltage requirement is 120V or 277V at 50/60 Hz
- Fixture enclosure accommodates ballast physical dimensions
As a used unit, this ballast is ideal for secondary applications, spare parts inventory, and cost-conscious facility upgrades where manufacturer warranty is not a requirement. For new construction or critical applications, consult the fixture manufacturer and verify all local electrical codes before installation. Installation should be performed by a licensed electrician in accordance with NEC Article 410 (Luminaires) and applicable local requirements.
