Here's another design approach to dispersing light evenly. It's GE's "omnidirectional" bulb that gives off as much light as a 40-watt incandescent, with cool-colored light, and consumes 9 watts. The life is expected to be 25,000 hours, which could be well more than 20 years. It's available now for $50.
