"Battery is our signature small lamp
shade made of transparent PMMA. Its innovation lies in the fact
that it can be recharged via a USB cable, and has up to six hours
battery life. This makes it easy to move: ideal for contract
segments, for use on caf or restaurant patios. Battery has a
crystal coloured cover with a faceted surface that creates
fascinating plays of light, and a frame in a metallic gold or
silver finish. Plus, there's also a version in different
transparent shades."
