The Multiquip MLBAL400 is a genuine OEM 400W 110V Ballast designed for Multiquip MB150, MB400, MB400B, MB1000, and MB1000W lighting systems. As a factory-authorized replacement, this ballast is built to the exact electrical specifications of the original component, ensuring the correct power output and ignition characteristics your lighting system depends on. Sourced directly from Multiquip, the MLBAL400 is the correct part for maintaining full lamp output and system integrity across compatible MB series lighting equipment.
Key Features
- Matched Electrical Output: — Rated at 400W and 110V to deliver the precise power level required for stable, full-brightness lamp operation in MB series lighting systems.
- Genuine OEM Component: — Manufactured to Multiquip's original design specifications, ensuring the ballast interfaces correctly with existing wiring harnesses and lamp sockets without adaptation.
- Broad MB Series Compatibility: — Confirmed fitment for MB150, MB400, MB400B, MB1000, and MB1000W lighting systems, covering a wide range of Multiquip portable lighting equipment.
- Protects Lamp Life: — A correctly functioning ballast regulates the voltage and current delivered to the bulb; a failed or mismatched ballast causes premature lamp burnout or failure to ignite entirely.
- Electrical Safety Compliance: — Using the correct OEM-rated ballast maintains proper circuit protection and reduces risk of overload or wiring damage in the lighting system.
A ballast is the electrical control device that regulates the voltage and current supplied to a discharge lamp, such as a metal halide or high-pressure sodium bulb. It provides the high-voltage surge needed to strike an arc and start the lamp, then limits current flow to keep the lamp burning steadily at the correct wattage. When a ballast fails or is replaced with an incorrectly rated unit, the lamp may flicker, fail to start, or burn out prematurely — leaving the lighting system unable to deliver the high-intensity output needed on the worksite.
