Mouth-blown glass shade: LED ceiling lamp Annex The designer lamp Annex by serien.lighting can boast both an elegant exterior and a sophisticated lighting effect. The conically shaped, mouth-blown glass body is very elegant with a little understatement. This clear, outer shade is complemented by an inner, also conical shade made of opal acrylic. The opal shade is essentially responsible for directing the light: on the one hand, Annex emits light downwards, but the opal shade also diffuses part of the light sideways, so that a gentle room illumination is given. Annex is a ceiling lamp that can be used in both private and commercial areas. Whether hotel corridor or domestic living room - all these areas are illuminated with style and finesse by Annex. The LEDs can be dimmed via a phase-cut dimmer.
