The 's' designation in this variation on the 28 refers to it being surfacemounted, with transformers mounted remotely. This surface light has a discrete 55mm (2.2") mounting plate designed for installation on walls or ceilings. 28 is an exploration of specificity in manufacturing. Instead of designing form itself, here the intent was to design a system of making that yields form.
Individual 28 pendants result from a complex glass blowing technique whereby air pressure is intermittently introduced into and then removed from a glass matrix which is intermittently heated and then rapidly cooled. The result is a distorted spherical shape with a composed collection of imploded inner shapes, one of which acts as a shade for the light source.
Standard 28s are made with clear glass exterior spheres and milk white interior lamp holder cavities. 28s are possible with infinite versatility in colour compositions, sizes and shapes.
