so if your saving 200 watts, that's 5 hours of use = 1 KWh.
A quick google says the national average in 2011 was 12c per KWh, it was 13.0 in Michigan i don't think it has gone up that much since then.
So to save $60 at 12c for each 5 hours = 2500 hours of use.
To recoup the cost in one year they would have to be on nearly 7 hours a day 365 days a year, so it depnds where they are.
We have plenty of lights, kitchen hallway, landing that get at least 5 hours even in the summer
That's just to recoup in 1 year, at 2011 electricity prices, LED's are supoosed to last 10+ years so plenty of time.
One my issues with LED's currently is that they only commnly availble to 60 watt equivalent, with some 75's. We like bright lighting, I want 100 watters. One thing I like about compact flourescent is you can out a 100 watt equivalent in a fitting that says '60W max'.
