LEDs get public's green light for holidays

When it comes to outdoor lighting, there is a downside to LEDs' cool temperature. That was made clear last weekend at the Toledo Zoo in Ohio, where the annual "Lights Before Christmas" holiday show was one of the first big public displays in the country to start making the move to energy-efficient lights, back in 2002.

"We had so much snow that we had to close the zoo," says spokeswoman Andi Norman. Some 35% of the zoo's million-plus holiday lights are LEDs now, she says, and while hot-burning incandescent bulbs kept shining brightly through the blanket of white, "it was hard to see the LEDs because they don't melt the snow."
