The seventies luminaire series offers a wide range of applications thanks to its diversity. The current family is the result of continuous product development based on many years of experience with museum-specific requirements. LED modules are available in two sizes. In combination with six reflectors, they extend the beam variance. It is also possible to customise the factory-configured illuminance when ordering. This allows planners and experienced end customers to influence key parameters such as luminous flux and system efficiency in advance. Heart of the series is the track spotlight tested for museum suitability with highest colour rendering index > 95 (typ. 97). Alternative models, configurations or light qualities for your project are possible as part of a customised production process.
