The US SNAP MAC USMFL400 400W IP66 LED Floodlight is engineered for maximum outdoor illumination where wide coverage and high brightness are essential. Designed for commercial, industrial, and large-scale residential security applications, this high-output floodlight provides dependable lighting performance in demanding environments.
Producing approximately 40,000 lumens at 100 lumens per watt efficiency, the 400W model is ideal for lighting expansive areas such as car parks, construction sites, warehouses, building exteriors, loading bays, and large gardens. The crisp 6000K daylight white colour temperature enhances clarity, improves safety visibility, and supports effective CCTV coverage.
With an IP66 waterproof and dustproof rating, the USMFL400 is built to withstand heavy rain, harsh weather, and airborne debris. The rugged housing ensures long-term durability in both commercial and industrial settings.
The wide 270° beam angle provides broad light distribution, minimising shadows and dark spots across large surfaces. A lifespan rating of up to 50,000 hours significantly reduces maintenance frequency and long-term operating costs.
Operating within a wide 85–265V AC input range, the floodlight is compatible with standard UK mains supply and suitable for various electrical installations.
Installation can be plug-and-play (where applicable) or hardwired to a wall switch. The adjustable mounting bracket allows secure fixing and directional control for precise light positioning.
