Robertson RSW234T12120 Fluorescent Ballast – 120V, 1-2 Lamps (T8/T12)

Overview

The Robertson RSW234T12120 is a compact electronic ballast designed for modern fluorescent lighting setups that run 1 or 2 lamps. It supports both T8 configurations (25–32 W) and T12 configurations (25–40 W), with preheat rapid-start operation. Built for improved reliability and efficiency, this ballast helps maintain steady, flicker-free illumination while staying space-conscious for retrofit projects.

Key capabilities

• Versatile compatibility: supports 1-lamp or 2-lamp runs for T8 (25–32 W) and T12 (25–40 W).
• Preheat rapid-start operation: optimized ignition and faster warm-up to reduce startup delay.
• Flicker-free and quiet performance: designed to minimize visual fluctuations and noise in occupied spaces.
• Energy-conscious design: enables efficient operation within standard ballast specifications for common fluorescent lamps.
• Compact form factor: ideal for space-constrained retrofits and compact luminaires.

Safety, compliance, and protection

• Safety certifications: UL Listed (Class P, Type HL, Type CC, Type 1 Outdoor) and CSA Certified (cUL).
• RoHS compliant and FCC Part 18 (Class B) EMI/RFI compliance for consumer environments.
• End-of-lamp-life protection and thermal safeguards to help prevent unsafe conditions.
• Internal surge protection and robust operating limits support stable performance across varying temperatures.

Performance and reliability

With proven end-of-lamp-life protection and built-in surge controls, the Robertson ballast aims to preserve lamp life and reduce unexpected failures. Its design prioritizes dependable operation in everyday lighting scenarios, backed by Robertson’s decades of ballast engineering and U.S.-based manufacturing expertise.

Why retrofit, why Robertson

This ballast is a strong fit for space-limited retrofits where you need flexible lamp pairing without sacrificing reliability. It’s engineered to align with a broad ecosystem of T8 and T12 lamps and to integrate into existing ballast footprints without extensive rewiring. The product line reflects Robertson’s commitment to design integrity and technical support.
