The world's first designer LED bulb, the Tube LED bulb has a sleek crystal resin finish, an E27 fitting and consumes just 1/50th the energy of conventional light bulbs thanks to Buster Punch's patented LED technology. A resin light pipe at the center of the bulb is where all the magic happens. It specifically allows the bulb to create a subtle ambient light, while simultaneously throwing a focused spotlight onto tables and surfaces below. Designed as a sculptural centerpiece, the Tube LED looks great hung over tables, bars, and bedsides. Available as a dimmable or non-dimmable bulb. Please note: When choosing the dimmable option, it must be used with a LED compatible dimmer switch, which is sold separately.
