Robertson IEA432T8120N Electronic Fluorescent Ballast — 3–4 T8 Lamps, Instant Start, 120V

Product overview

The Robertson IEA432T8120N electronic ballast is designed to power 3 or 4 T8 fluorescent lamps, including common configurations such as F32T8, F25T8, F17T8, and F40T8. This unit emphasizes a compact, lightweight form factor that fits a wide range of retrofit and replacement projects while delivering dependable, instant-start performance.

How it helps in real-world setups

In parallel-lamp configurations, the ballast accommodates mismatched lamps and keeps each lamp operating independently. This means you can upgrade an older fixture with mixed lamp types without risking misfires or prolonged warm-up times. The instant-start technology aims to reduce delay between switch-on and full illumination, supporting efficient start-ups in busy commercial spaces or home offices.

Its 120V design aligns with common residential and light commercial wiring, simplifying installation by removing the need for multi-voltage considerations. The ballast is engineered for remote mounting up to 18 feet, with pre-wired 18 AWG leads to streamline wiring and mounting in fixtures, retrofit kits, and ceiling channels.
