Product Overview
The Sylvania Lumalux LU400/120/277-KIT is a complete replacement ballast kit for 400W S51 High Pressure Sodium fixtures. The kit supplies the magnetic core and coil, dry capacitor and pulse start ignitor together, so the electrical components are matched to each other.
Its CWA circuit regulates lamp power through input voltage swings. Wire to the tap that matches your branch circuit: 120/277V.
Compatible Applications
- Replacement or rebuild of 400W S51 HPS fixture ballasts
- Commercial, industrial and outdoor HID fixture maintenance
- Cold-weather installations (minimum starting temperature -40°F)
Compatibility and Cross-Reference
- Operates one 400W S51 HPS lamp.
The Sylvania cross-reference guide lists no comparable Advance, Universal, Venture or Howard part number for this item.
Before Ordering - Verify
- Confirm lamp wattage and ANSI code: 400W S51. This kit is not interchangeable with other HPS wattages.
- Confirm your circuit voltage matches one of the taps: 120/277V.
- Confirm physical fit against the catalog ballast figure (Figure N).
- Ballast kit only; the lamp and fixture are sold separately.
Safety and Installation Guidelines
- High voltage pulse is present on the open circuit. Ground the ballast core and the metallic cases of the capacitor and ignitor.
- Disconnect power before installing or servicing.
- Install in accordance with the National Electrical Code (NEC) and local codes.
- Follow the included installation instructions and wiring diagram.
