How many hours does 1540 milliamps of power equal?

None. The time depends upon the capacity of the delivery system, eg a battery with a rating of 1200mah (1200 milliamp hours) means it holds enough charge to deliver 1 milliamp for 1200 hours; or it can deliver 2 milliamps for 600 hours, or 1200 milliamps (=1.2 amps) for 1 hour, or 3600 milliamps (= 3.6 amps) for 1/3 hour (= 20 mins), etc.
