It's a physical law: illuminance recedes with the square of the distance between the light source and illuminated plane. This is the reason why high-lumen output luminaires are needed for wide lighting distances and high rooms - for example when showcasing vehicles in a trade show hall, for large sculptures in a museum foyer or for uniform wallwashing in an airport. The name Stella in the ERCO product spectrum represents high-performance spotlights, floodlights and wallwashers for track mounting. The product range provides efficient replacements for existing applications using 150W metal halide lamps. The Stella family consists of two construction sizes and all light distributions within the ERCO system of luminaires generated by reliable and highly efficient Spherolit lens optics. As a result, complex lighting tasks can be flexibly and consistently resolved. The purist, technical design of the cast aluminium housing achieves ideal thermal conditions and therefore reliability and a long service life.
