Early Style Edison Reproduction Light Bulbs
By James Grahame
The incandescent light bulb hasn't really changed much in a hundred years. In fact, you can still buy a reproduction of the original Edison bulbs from the 1890s. This 6" clear glass bulb emits a dim reddish glow from a single loop carbon filament. It has a 2000 hour average life and emits a soft glow far gentler than a modern 40W incandescent. Because of the fragile filament, it should only be mounted vertically.
Is it worth $13.49? That depends. We're rapidly approaching the time when an inefficient incandescent of any type will be seen as a quaint museum piece. And it definitely beats having to refill my oil lamp every night.
