Finally light bulb's Tesla tech gives LEDs a worthy rival

Ever since I improbably started blogging occasionally about light bulbs, I've been waiting impatiently to get a look at the first product from The Finally Light Bulb Company. This start-up company from Cambridge, Massachusetts has decided to bring a Tesla-era lighting technology into the consumer space. The tech is known as induction or electrodeless lighting. Induction tech is pretty closely related to fluorescent lighting: a magnetic field excites gases in an enclosed tube. Those gases generate UV light, which strikes the phosphor coating on the tube, causing it to glow. (I'm probably butchering the details, so go here for more info.) Induction lighting has been used for years in industrial and commercial settings, where its reliability and efficiency are appealing, but the fixtures have been much too large for use in the home. The folks at Finally have worked to miniaturize induction lighting radically, so an entire assembly will fit into the space of a conventional A19 light bulb.
