Attic lights

Any information on the rules related to the installation of an attic light would be appreciated.

Fire Codes
area served (sq feet)
NEC / IRC (other than IRC E3803.4)

The only requirements are that if that attic is used for storage or the has equipment installed in it that needs servicing, a switch controlled light needs installed at or near the normal entrance. This could be a wall switch or a pull string on the fixture. If there will be employees of a company working on the A/C, the minimum lighting levels are 10 footcandles.
