Shark is a spotlight-series for the illumination and presentation of shops. The focusable reflector allows an infinite adjustment of the beam angle between 15 and 40 degree (Flood/Spot). So various light-effects are adjustable without the slightest effort. The structuring of the spotlight corpus follows forcefully the thermal separation of the light sources and the power supply unit as well as the minimisation of thermal bridges. This enhances, in combination with the efficient, gills-like deaeration, the life-time of the light-technical components. Shark features a multiplicity of reflector and equipment versions. By the use of flashing, coloured and transparent glare shields, interesting effects can be attained, which make light visual in a supplementary way.
