Hanging lamp Greenwich with opal coloured glass shade The Greenwich hanging lamp is characterized by concentric lines on mouth-blown glass. The white glass has the shape of a sphere drawn out in length and the light can escape glare-free and warm from the glass shade. Especially the glare-free characteristic makes Greenwich suitable for quiet environments, such as the bedroom. Note: With mouth-blown glass, air pockets may occur. This is a sign of craftsmanship and makes each lamp unique.
