Here is a description from the web:
Design duo Mischer’Traxler, Wien | Austria, started their project to focus on light sources and came up with the idea to combine two lamps into one. This way they created a new design that uses a energy-efficient fluorescent tube bulb and gives the lamps a whole new character. The name of this lamp is ‘Relumine‘ and plays on the fact that we all have to switch from old light bulbs to new energy saving light sources. The fun and challenge is to combine different type of lamps, like a hanging pendant with a floor lamp, a floor lamp with a desk lamp or different heights and hardware.
Each Relumine uses two, discarded lamps, which are disassembled, sanded, newly lacquered and adapted with newer technology, before they are connected by a glass tube which holds the fluorescent tube. Together these two lamps need less energy than each one in its previous life.
