Delta Light calls its Tweeter series a "classic of the future" because the series is extremely flexible and future-oriented. Thanks to the patented eccentric rotation process, it is possible to turn and tilt the diffuser very much. This is made with a continuous movement and not step-by-step. Not only is the light body mobile, but there are also many lighting possibilities. The unique pivoting mechanism of the spot light for wall and ceiling Tweeter M 1 On ensures an efficient use of the light beam serving as a wall-washer. The bowl forming the spot Tweeter M On for surface mounting produces an ideal cooling effect which extends the light span of the integrated LED lamps up to 50 000 hours. The aesthetic design of the Tweeter series is underlined by the "Oreo principle", an elegant lighting halo around the integrated LED lamps located in the middle. Tweeter On is available as a unique spot light and as double spot light.
