LED Lightbulbs with an Almost Infinite Life


They are here in Canada in Walmart stores and you can buy them for about $13 a bulb that runs cold and lasts almost for ever (100,000 hours is an understatement).

The fluorescent replacements to incadescent are a big improvement, but the LEDs are the 'major' leap forward.
