LED light bulbs make sense now

If used an average of five and a half hours per day, the new bulbs can last up to 19 years, according to Panasonic. That's 40 times longer than incandescent bulbs.

Since you would have to buy 40 regular incandescents to do that, the price of the bulb (around $40) is about the same (40 incandescents at $1 each)

The bulbs use only an eighth the power of incandescents. That means a 60-watt-equivalent LED bulb would cost only 300 yen (about $3) a year instead of 2,380 yen ($25.80)--a significant savings over a lifetime.

This means $1,000 in electricity for the incandescent versus $100 for the LED.

They make economic sense now, especially for the few lights you leave on all the time, and the price should drop to less than 10 dollars in a few years.
