Yes. All ballasts are brand new, unused, and have never been installed. Some may have been tested and have wires. Many are discontinued or difficult to source, making them ideal for maintenance, retrofits, or matching existing systems.

Many Lutron ballasts have been discontinued or replaced by newer technologies. These units are often no longer available through standard distribution channels, making remaining inventory limited and in high demand.

Compatibility depends on the specific model and your current lighting control setup. It’s recommended to match part numbers exactly or consult Lutron documentation to ensure proper integration.

Warranty availability may vary. Since these are legacy or discontinued products, manufacturer warranties may no longer apply, but seller return policies may be offered—check the listing details.

These ballasts are ideal for maintaining or repairing existing Lutron lighting systems in commercial, residential, or institutional settings where replacing the entire system is not practical or cost-effective.
