Crystal Tube was designed by Englishman Lee Broom in 2015 and is produced under his brand and name. The lamp is made of hand-engraved clear crystal glass and its shades are made of either brushed brass or chrome-plated steel. With Crystal Tube, Lee Broom wanted to create a luxurious interpretation of a light tube. This is proven, for example, by the crystal glass, which gives off a sparkling glow when the lamp is lit. Besides this glass lamp, Crystal Tube is also available as a pendant lamp.
