I understand that, but to be more "user friendly" allow the user to 
enter the actual life time of the incandescent bulb (1200hrs?) and use 
the power of the spreadsheet to convert it to the 10000 hour equivalent 
rather than forcing the user to do the calculations.  In other words, if 
you're forcing the user to do the calculations it brings into question 
why you're using a spreadsheet to begin with.

For more user-friendliness, I would add another sheet/page as the first 
page and have it very simple where they would just enter the simple data 
and get back the results.  The current spreadsheet is too "techy".
