Classical 5 Series

A new addition to the 5 Series, EURUS-LT is the first multi-function profile luminaire of the AYRTON ‘‘LT’’ (Long Throw) product line designed for long-distance applications. EURUS-LT is also the first product launched under the new SLIM-21 programme for miniaturising fixtures and reducing their weight. AYRTON has developed a high-efficiency 850 W power supply in an entirely new die-cast aluminium base that takes up 33% less volume than in other luminaires of the same category. A lighter internal structure and all-new miniaturised stepper motors add to the final result. This new luminaire boasts optics specifically developed for applications requiring perfect image reproduction and significantly reduced distortion caused by the shutter blades in wide zoom. Fitted with a 168 mm frontal lens, the proprietary optical system uses 13 lenses, producing an 11:1 zoom ratio and a zoom range of 4.5° to 48°. Equipped with a new 550 W ultra- compact monochromatic LED emitter calibrated at 8000 K, it can deliver metallic white light with an output of 32,000 lumens at a colour temperature of 6700 K.

Feature-packed from the factory, EURUS-LT includes a subtractive CMY colour mixing system combined with a variable CTO and a six-position complementary colour wheel for displaying an infinite palette of vivid pastels and saturated colours. The framing section allows accurate positioning of each shutter blade on a 100% surface area in all positions, so that the user can frame any object regardless of the luminaire’s position. The image section includes 18 interchangeable HD glass gobos on two wheels: one rotating wheel with seven positions and one fixed wheel with eleven positions. The effects section includes one continuous dynamic effect-wheel, 15-blade iris diaphragm, two frost filters (one for light and one for heavy diffusion), two rotating prisms (one circular with 5 facets and one linear with 4 facets). EURUS-LT has a highly efficient phase-change liquid cooling system using a heat pipe that includes a particularly effective ultra-silent ventilation mode, designed for stage and studio applications.
