Lüdenscheid, October 2015. Public buildings such as museums, libraries or train stations stand apart as architectural landmarks in any urban context. Much like a big plaza in the city’s fabric they are nerve centres of urban life. Effective illumination enhances the fascination of these places and adds to the city’s appeal, lending it even more character. With the new Kona range, ERCO now offers versatile luminaires for a multitude of outdoor applications. Thanks to powerful luminous flux packages combined with excellent glare control, Kona is a perfect lighting tool, particularly for extended projection distances, and offers glare-free visual comfort. The robust luminaires with highly innovative ERCO LED photometrics illuminate large façades and monuments as effectively and with impressive energy efficiency results as building ensembles.
The Kona range, consisting of projectors, floodlights and wallwashers, is the latest release of lighting tools designed and developed at ERCO. Its innovative style combines visual comfort with energy efficiency in a robust housing. With astonishing lumen packages of up to 12,720 lm at just 109 W of power consumption, Kona masters large projection distances effortlessly, making the luminaire ideal for lighting tasks over longer ranges. The sophisticated design of the round, tapered housing, with an optical system set back deep inside the luminaire, guarantees optimum glare control even with maximised lumen packages. A huge range of distribution options projects the powerful light precisely onto the target surface without any loss to widen the photometric options of creative lighting design. Maintenance-free optoelectronics and the corrosion-resistant housing are designed for a long life to help save natural resources and reduce the operating costs.
Powerful and flexible
Kona is available in three sizes for total compatibility with all typical outdoor project challenges. In all three sizes, the projectors, floodlights and wallwashers excel with corresponding lumen packages and a variety of light distributions. Architectural details are emphasised effectively with the Kona projector using a narrow distribution with a cut-off angle of 30°. As a floodlight with oval flood distribution, Kona lends itself to the accentuation of tall and long objects, such as free-standing sculptures. The Spherolit lens oval flood in the round luminaire head of Kona can be rotated freely allowing precise adjustment of the elongated beam to illuminate individual objects. As a wallwasher, Kona produces absolutely uniform vertical illuminance across building façades and helps to define spatial borders.
Efficient and low-maintenance photometrics
With exceptionally uniform light produced by the Kona projectors, floodlights and wallwashers, only a few of these lighting tools are needed for a lighting concept designed to satisfy the highest standards. The specially developed Spherolit lens system, based on a combination of LED module, collimators and Spherolit lens, focuses the digital light of Kona perfectly, offering powerful lighting tools with energy usage as low as 19 W to 96 W. As well as this outstanding achievement, ERCO photometric solutions are designed for a long life, guaranteeing low-maintenance requirements with lower operating costs. With excellent lumen maintenance (specification of L80/B10), Kona is superb for operation particularly in mounting locations with challenging access, such as bridges or roof structures. The robust housing is made of corrosion-resistant cast aluminium and thanks to a double powder-coated and an IP65 rating, the system is ideal for a multitude of lighting tasks in the outdoor area as well as for indoor applications that call for a high degree of protection.
