Light bulbs are becoming a gold rush. A venture-backed startup has announced an under-$10 incandescent replacement light bulb based on induction technology.

The Finally Light Bulb Company uncloaked today. It was featured in The New York Times yesterday and in many other news outlets today. Its 60W-replacement, 800-lumen bulb, as you can see, looks almost exactly like a traditional A19 incandescent. Various outlets say that the target price of the Finally Acandescent will be $7.99 when it becomes available this summer -- but when you go to the company's pre-order page, it says you'll pay $9.99.
Ron Lenk's induction primer offers some background on how the technology works. He concludes: "I should mention that I've seen an induction lamp configured to resemble an A19 (vaguely). It was this big honking thing that must have weighed a pound, and had a huge bulge in the middle where the coil was."
Finally does seem to have accomplished the downsizing of induction technology to fit comfortably into an A19 envelope -- not a trivial accomplishment. It hired senior scientists from Osram Sylvania and GE to get this done. The bulb's weight is not stated, but it looks like it might mass less than a typical LED-based bulb.
