and cost of electricity is actually closer to 10 cents per kwh, not 20 that was used in the calculations, at least that's what it is here in Illinois...
so you invest 10x more upfront to save 40% ($60 saving / $160) over 17 years...
I can't really be bothered to calculate it out, but my guess is that you would be better off just buying cheaper bulbs and investing the difference elsewhere...
