Assume a 40-watt bulb lasts 1000 hours.

40w x 1000 = 40 kwh x $0.15/kwh = $6.00 operating cost over life of bulb.

The new bulb uses 9 watts. So for the same period,

9w x 1000 = 9 kwh x $0.15/kwh = $1.35 operating cost.


Over the life of the bulb, the savings is considerable, about $116.

Right now, I'm not going to pay extra for a bulb that is going to last
longer than me. They need brighter bulbs and decent color. I wonder if
they've done anything about that. I did buy an LED nightlight for the
bathroom. It is 4W, IIRC and bright enough. It gives a very blue light and
in a blue bathroom it is kind of overkill on blue. Good enough to take a
leak middle of the night, now something I'd want to live with all the time.

I imagine the price will come down over time, just as the CFL has in recent
years. They went from $20 to $1 and improved the light color too.
