Product Overview

The GE 72266 GE232MAXP-N/ULTRA is a high-efficiency multi-volt instant start electronic ballast designed for general fluorescent lighting applications using one or two compatible T8 lamps. It operates on 120-277V input and is positioned as a normal-output ballast with 0.87 ballast factor. :contentReference[oaicite:3]{index=3}

This ballast includes Active Current Regulation and Anti-Striation Control, making it a strong fit for standard commercial fixtures where stable lamp performance and broad voltage flexibility are important. Seller and legacy GE references also support that GE232MAXP-N/ULTRA replaced 232MAN-N/ULTRA. :contentReference[oaicite:4]{index=4}

Why Choose This Product

• Multi-volt flexibility: Operates on 120V through 277V systems.

Compatibility & Replacement

Fixture type: Designed for compatible fluorescent fixtures using 1-lamp or 2-lamp T8 systems across common 24-inch, 36-inch, and 48-inch lamp families. :contentReference[oaicite:5]{index=5}

Replacement note: Available references support that GE232MAXP-N/ULTRA replaced 232MAN-N/ULTRA. Because some distributor pages still show older and newer naming inconsistently, it is smart to confirm both the model and lamp matrix before substitution. :contentReference[oaicite:6]{index=6}

Before ordering, confirm:

• Lamp count: Verify whether your fixture uses 1 or 2 lamps.
• Lamp type: Confirm your exact lamp family and wattage.
• Input voltage: Confirm supply is between 120V and 277V.
• Physical size: Verify ballast channel fit.
• Replacement goal: Match normal ballast factor performance if replacing like-for-like.
