Long Life Light Bulb Has 6 Different Filaments
If you like the idea of a long-lasting light bulb but aren't crazy about the light given off by fluorescent bulbs or the price they go for, you'll want to check out this new concept in long-life bulbs.
  Charles Little's prototype "programmable" incandescent light bulb debuted at the recent Minnesota Inventors Congress at Redwood Falls, Minn.
  It consists of a regular-size incandescent bulb containing 6 filaments that plug into a reusable base. The filaments can be operated singly or simultaneously in groups depending on the level of light you want. When one filament burns out, you simply turn the bulb in the base to select the next filament. When all the filaments are burned out, you simply insert a new set of filaments.
  The design also allows the bulbs to be operated at different voltages, Little notes.
  "It should last at least five times as long as a conventional incandescent bulb with standard filaments and should be comparably priced," he says.
  Little is looking for a manufacturer.
