Not through solar power, not through electricity, but with fireflies? Well not exactly, but it sure does look like it. The firefly lamp is a bulb suspended over an acrylic base with a chrome rod that has the internal filament set up to look like 5 fireflies floating inside. An interesting light piece to look at but definitely not something that you can curl up beside to enjoy reading your favorite book. Hopefully the internal "fireflies" don't move around in there.
Available here for $99.
