The needs are different, depending on what each room would be used for. 
And the guidelines are given in illuminance, since lumens per watt 
differs wildly from fixture to fixture.

Digging into an old textbook, I found this chart --

If the link doesn't parse, it's from "Industrial Electricity
By Michael E. Brumbach" Table 14-2, Machine Shops & Assembly Areas.
