There are 1,000 miliamps in 1 amp. As the NEC limits you to loading a lighting circuit to no more than 80% you can have 16 amps or 16,000 miliamps on that circuit. That would mean you can have 2,000 lamps of 8 miliamps each.

You can put 2500 8 milliamp lamps on a 20 Amp circuit because 20 Amps is equivalent to 20,000 milliamps. To find the number of lamps, you divide 20,000 by 8.
