When it comes to fluorescent lighting, we look to the design-worthy light bulb from Plumen. The popular European bulb is now available in a US version (110V), saves 80 percent on energy, and lasts eight times as long as a standard incandescent bulb.
The Plumen 001 Light Bulb is no different in functionality than the standard screw-in fluorescent bulb; it stands out for its sculptural form and the fact that it radiates warm white light. The bulb is priced at $29.95 in the US for either the screw or bayonet fitting.
