If you haven't heard of Monoqi before, it's quite similar to Fab, but with higher-end design products on its virtual shelves, all at discounted prices. It's also a European site, but does ship to the UK. Right now, there's a Bauhaus lighting sale on,, which includes this classic HMB 25/500 modernist suspension lamp.
Specifically, it's a sale of Tecnolumen designs, which is a licensed manufacturer or iconic Bauhaus designs, as well as similar designs from the era. The HMB 25/500 light was the work of Marianne Brandt and Hans Przyrembel back in 1925, featuring a unique height adjustment pulley system, a polished nickel-plated finish and consecutive numbering. Each is also stamped with the Bremen-based light manufacturer's seal.
€709 is the price, down from €835. See all the designs (and other sales) on the site.
