*Overall this looks good. It appears the assumptions uses energy at 8.2 cents and the input page is based on 8.7 cents. Also, not sure how much taxes and shipping costs will be for the items considering $4 for lights is already a fairly low estimate based on your link. Finally, I didn't understand why only 25% of ballasts had to be replaced at 6 year mark, what about the other 75%? Also, businesses may be concerned to assume a 6 year life when the warranty states 5 years, unless you can find a source that indicates average life. | *Overall this looks good.
