ratio

Ratio is a contemporary styled post top luminaire manufactured from fully cast aluminium housing that supports 48 LEDs (Light Emitting Diodes) engineered to produce illumination equivalent to a traditional 100 watt metal halide lamp.

Its stylistic and ultra thin “finned” design serves both as an architectural statement and thermal heat sink for the LEDs. Optical control is achieved through the marriage of individual refractors influencing each LED independently. The driver module is conveniently mounted at the base of the column for maximum thermal management. Ratio is available as a complete lighting solution with bespoke Holophane conical steel and conical aluminium columns.
