People say you can't do much with lighting, but just add up how many Wh the lighting in your house uses per month, and how much power you could conserve by cutting that in half. I've found the numbers to be significant.

30W per fixture savings x 3 fixtures = 90W. If you pay 10 cents per KWH you need to save 100KWH to save $10. 100KWH/90W savings = 1,111 hours per month. Problem is there are only 720hrs in a month.
The bigger thing that determines payback time is how much the mod costs. At retail prices the value isn't there. If you can buy the items at substantial discount then payback times are a lot shorter.
