Caleo-X1 LED ceiling light - efficient lighting for the office The elongated Caleo-X1 LED ceiling light consists of a body made of extruded aluminium profile, which is coated with silver-coloured textured paint. A diffuser made of micro-structured special acrylic guarantees an excellent distribution of light. The warm white light of the built-in LEDs shines downwards extensively through the white diffuser, while an indirect corona of light appears on the ceiling all around the body. A dimmable 1-10 V EB is built into the light. The desired level of lighting can be adjusted via a 1-10 V dimmer (not included). Along with the electrical cable (three-core), a two-core control cable is also needed for this. Energy efficiency class:A+
