Bellevue has a 
bright idea: Use LEDs in streetlights to save money

Just as homeowners are switching to compact fluorescent lightbulbs to save money and energy, so too are cities — on a large scale. Bellevue is exploring converting its 4,790 streetlights to LEDs in the hope of saving more than a third of its $1 million annual power bill. The change would replace the warm yellow glow of high-pressure sodium lights familiar since the 1960s with a clear, bright white light that some studies say increases visibility.
