Lightcast recessed luminaires are completely subordinate to the light they emit. They are so thoroughly integrated in the ceiling that they barely register as a design feature. The most important factor determining the effect created by space and objects is the play of light on surfaces. Light emitted by downlights can vary from very narrow beams to diffuse wall illumination. All Lightcast downlights have cast aluminium housings providing optimal thermal propertiesaccording to their respective technical requirements.
