The idea behind their design was to make the bulb invisible in order to create a dazzle free light. from their inception in 1931 sistrah and muller produced a range of lighting from desk lamps, pendant lamps, medical lamps, billiard lamps and even street lamps. Their clever branding slogan ‘sie strahlt hell’ (she burns brightly) (sistrah), their annual catalogues and the amazing built quality made sistrah the lamp of choice for many business owners. condition report fully rewired with modern electrical components, some patina to the brass surface i have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution, up to 250v (europe/uk standard).the wiring of this item may be original and might need replacement, if not specified otherwise.
