Wacker Neuson 5000403932 MH Bulb 400W

The Wacker Neuson MH Bulb 400W is a genuine OEM replacement bulb designed for ML440 and ML240 series Light Towers and Multifunction Floodlight Towers. As a factory-sourced component, is manufactured to the exact output and electrical specifications required by these machines, ensuring the lamp operates at the correct wattage and light intensity from the moment it is installed. This bulb fits across a broad range of ML440 and ML240 configurations, including RAW-designation units, making it a reliable single-source solution for operators running multiple tower variants on the same jobsite.

Key Features

• Correct 400W Output Rating — Matched to the designed wattage draw of ML440 and ML240 lamp housings, so the ballast and fixture operate within their intended electrical parameters.
• Genuine OEM Sourcing — Supplied directly from Wacker Neuson, ensuring the lamp arc tube, base type, and envelope dimensions are identical to the original — no guesswork on fitment or output.
• Broad ML-Series Compatibility — Confirmed fit across ML440 and ML240 Light Towers and Multifunction Floodlight Towers, including standard and RAW-designation models.
• Full Light Output from First Strike — A worn or failed MH bulb produces reduced lumen output, uneven color temperature, or fails to strike entirely; a fresh OEM bulb restores full-field illumination for night operations.
• Electrical Safety Compliance — Using the correct OEM-rated bulb in metal halide lamp circuits is critical; a mismatched wattage or base type can overstress the ballast, damage the fixture, or create an arc hazard.

A metal halide (MH) bulb is the high-intensity discharge lamp at the heart of a light tower's flood illumination system. It produces light by passing an electrical arc through a pressurized mixture of mercury vapor and metal halide salts, generating a bright, white light output suited for large-area site lighting. When the bulb nears the end of its service life it may flicker, take longer to strike, or fail to reach full brightness — any of which significantly reduces usable light on the work area and places additional strain on the ballast as it repeatedly attempts to restart the lamp.
