Product Overview
The GE 74111 GE332MAXP347-H is a 347V instant start electronic ballast designed for 3-lamp T8 fluorescent systems. With a 1.18 high ballast factor, it delivers stronger light output than standard-output models and is intended for applications where higher lumen performance is needed. :contentReference[oaicite:6]{index=6}
This ballast is built for 347V commercial and institutional electrical systems, making it a fit for facilities where 347V distribution is standard. Its high-output performance is useful when replacing older high-ballast-factor units or when standard 0.87 models do not provide enough light. :contentReference[oaicite:7]{index=7}
Why Choose This Product
- High light output: 1.18 ballast factor supports brighter system performance.
- 347V compatibility: Built for 347V commercial systems.
- 3-lamp application fit: Designed for 3-lamp T8 ballast layouts.
- Instant start operation: Good for general fluorescent lighting applications.
- Compact housing: Low-profile design fits many standard fixtures.
- Useful replacement option: Helps match older 347V high-output ballast applications.

Compatibility & Replacement
Designed for: 3-lamp T8 fluorescent systems on 347V input. This is a voltage-specific, lamp-count-specific ballast and should not be substituted with standard 120-277V or 2-lamp models. :contentReference[oaicite:8]{index=8}
Important: This is a high ballast factor (1.18) model. Do not substitute it with a 0.77 or 0.87 ballast factor version unless reduced light output is acceptable. :contentReference[oaicite:9]{index=9}
Compliance & Certifications
- FCC 47 CFR Part 18 Non-Consumer
- RoHS compliant
- UL Type 1 Outdoor
ADL Supply recommends confirming input voltage, lamp count, ballast factor, and fixture compatibility before ordering.
