The 9 watt GE LED replaces a 40-60 watt incandescent, has a limited warranty of 10 years, and is rated for 22 years. Wow.
The odd-looking heatsink helps send light downwards and to the side. It’s expensive now, $50, but in a few years Wal-Mart will be selling them by the millions and the price will be what CFLs are now. Let’s not forget, CFLs were quite expensive when first introduced too.
And of course, LEDs have no mercury in them.
LEDs aren’t just for home use. Municipalities are discovering that LED street lights are more cost-effective than other types of street light.
