How to figure Lighting requirements

I have tried to search for a table or equation for figuring how much lighting how many total lights) a room needs. I know this subjective as to how bright you want it, but years ago I ran across a lighting calculator that helped figure lighting (how much total wattage equally spaced) dependant on whether you want low light(mood lighting) , normal visability or high visability. Any one have any ideas? My man concern is for a main recording room 31 feet long by 14 feet wide with 9 foot ceilings. Thanks for any help. Tom
