Grazing light is an exceptionally effective method for illuminating building façades, bringing out intricate surface textures through high-contrast shadows and striking visual depth. The Focalflood façade luminaire from ERCO is purpose-built for this application, delivering narrow, precisely controlled light distributions that transform vertical surfaces into captivating architectural features. Its optimized lens system supports wide luminaire spacing while maintaining excellent uniformity across the wall, ensuring efficient coverage with minimal spill light. The result is a beautifully even wash of light that reveals subtle material details and adds a dramatic layer of visual interest to natural stone, textured concrete, or other three-dimensional façade surfaces.
Designed for flexibility and performance, the Focalflood luminaire features an easily adjustable housing that allows for precise orientation and a smooth 135° tilt. This helps to fine-tune the angle of illumination, ensuring that the light grazes the wall surface effectively while avoiding unwanted glare or upward spill. The grazing light technique employed by Focalflood also contributes to environmentally responsible lighting design, supporting Dark Sky principles by minimizing light pollution and directing illumination strictly where it's needed.
The luminaire’s construction reflects ERCO’s dedication to quality and longevity. It incorporates a high-performance LED module with options for warm white (3000K) or neutral white (4000K) light, with additional variants available in 2700K, 3500K, or CRI-optimized versions on request. The asymmetrical reflector lens system is crafted from silver-anodized aluminum and features no direct light components thanks to the precisely shielded LED arrangement. The front unit and housing are made of corrosion-resistant aluminum with a No-Rinse surface treatment and double powder coating in graphite m, providing durability and reduced dirt accumulation. The integrated Softec lens ensures soft transitions and precise beam shaping, while screw-fastened end plates and two freely positionable mounting brackets enable secure and flexible installation.
The luminaire is IP65-rated, ensuring it is dust-tight and resistant to water jets, making it suitable for demanding outdoor environments. Control options include switchable or DALI dimmable drivers, allowing integration into modern lighting control systems. Each unit is delivered with a 1.5-meter connection cable and can be mounted in a continuous row for optimal façade illumination. For customization, ERCO offers up to 10,000 additional housing colors and a range of high-CRI LED configurations tailored to specific architectural needs.
Through its combination of advanced optics, robust engineering, and refined aesthetic, the ERCO Focalflood façade luminaire provides lighting designers with a powerful tool to emphasize textures, accentuate architectural forms, and deliver sustainable, visually engaging nighttime façades.
