Wacker Neuson 5000088505 1000 Watt HPS Coil Ballast

The Wacker Neuson is a genuine OEM 1000 Watt HPS Coil Ballast designed for the LT4SK, LTP4SK, LT4SZ, and LTP4SZ light tower series. As a direct Wacker Neuson OEM part, the is built to the exact electrical specifications required by these light towers, ensuring correct ignition and stable lamp operation. This coil ballast is a verified fit for all four tower models listed, making it a straightforward replacement for a failed or degraded unit.

Key Features

• Correct Electrical Output Rating: — Rated at 1000 watts to match the HPS lamp system in Wacker Neuson LT4SK and LTP4SK series light towers exactly, with no output mismatch.
• Genuine OEM Component: — Sourced directly from Wacker Neuson, this ballast carries the same part specification as the unit installed at the factory, eliminating compatibility guesswork.
• Direct Drop-In Replacement: — Designed to connect into the existing lamp housing and wiring on the LT4SK, LTP4SK, LT4SZ, and LTP4SZ towers without reworking the fixture.
• Lamp Strike and Arc Stability: — A functioning ballast delivers the high-voltage ignition pulse needed to strike the HPS arc and then regulates current to hold a steady, full-brightness output throughout the burn cycle.
• Electrical Safety Compliance: — HPS ballasts operate at high ignition voltages; using the correctly rated OEM unit for these towers ensures the lamp circuit stays within its designed voltage and current envelope, protecting both the fixture and the operator.

The coil ballast is the electrical heart of a high-pressure sodium light tower lamp circuit. It performs two critical jobs: delivering the high-voltage spike needed to ignite the HPS arc tube at startup, and then limiting the current to keep the arc burning evenly at rated brightness once the lamp reaches operating temperature. When a ballast fails or drifts out of specification, the lamp may fail to strike, flicker during operation, or burn at reduced output — leaving the worksite underlit and the tower effectively out of service. Replacing a worn ballast with the correct-rated unit restores full light output and protects the lamp from premature failure caused by irregular current delivery.
