I'm sitting in an office right now that's solely lit by warm white LED GU10 bulbs. When we had halogen bulbs installed (10 of them) we were using 500W of power, now we are using 40W of power. At 8 hours a day (they are on that much easily) they use 117 kwh per year. The halogens that we replaced would use 1460 kwh per year.

117 kwh @ $0.08 = $9.36
1460 kwh @ $0.08 = $116.80

A savings of $105 per year, just for one room.

That doesn't even take into account that our air conditioning runs far less often.
