Norlake 39423 Light Ballast 18-48 in Bulbs 120V 60hz

Product Description

The NORLAKE 39423 is a replacement light ballast designed for commercial refrigeration and food-service equipment using 18-inch to 48-inch fluorescent bulbs. Operating at 120 volts and 60 Hz, this ballast regulates current to the lamp to ensure stable, consistent illumination inside walk-in coolers, reach-in cases, and similar NORLAKE commercial appliance installations. It is a direct OEM replacement part installed by commercial refrigeration technicians and qualified service professionals performing lighting system maintenance or repair on NORLAKE equipment.

This ballast is suited for commercial food-service environments where interior case lighting must remain reliable under continuous duty conditions. Typical installation scenarios include walk-in cooler interiors, display case lighting circuits, and other enclosed refrigerated compartments fitted with fluorescent lamp assemblies in the 18-inch to 48-inch range. When the original ballast fails or causes flickering, dimming, or lamp startup failures, the 39423 serves as the designated OEM-compatible replacement for affected NORLAKE units.
