The Oseris group of spotlights is designed almost entirely around the advantages of halogen technology: good optical control of the emitted beam, brilliant white light and excellent colour rendition. The perforated metal housing adds the impression of lightness to the luminaire. Using the graduations indicating the angle of tilt, the luminaire can be aligned exactly, making it highly suitable for museums and exhibitions. The transadapter for mounting on the ERCO 3-circuit track features an integral potentiometer to dim the lamp between 10 and 100%. The comprehensive range of accessories, such as anti-dazzle attachments, lenses, colour filters, UV and IR filters, are held in place by a mounting ring.
