I have replaced all my halogen down lights , 50w each, with LED lights that use only 5w, and actually provide better light.
I typically have 15 on, 4 hours a day.
As a proportion of my overall power usage, my lighting has dropped from about 15% to 1.5%
The LED bulbs will last longer (10,000 hours) than halogens, and pay themselves off in terms of saved electricity, in 2 years.
Electricity is $0.26
it will take 777 hours for it to save it's own purchase cost in electricity, or approximately 194 days of typical 4 hours a day use.
Definitely worth while both economically and environmentally.
