You have to know the watts of each fixture to determine how many total you can put on a 15 amp (14 gauge wire) branch circuit. At 120 volts a 15 amp branch circuit can deliver 1800 watts, soooooooo you can draw a maximum continuous load of 80% of that which is 1440 total watts. Soooooo if the light fixtures were say 80 watts each, then 80 goes into 1440 18 times i.e. 18 lights = 1440 watts = 80% of the 15 amp 120 volt branch circuit continuous capacity.

Now all you gotta do is to know the total watts per fixture (thats the bulb(s) PLUS the Ballast) and see how many it takes to add up to under 1440 and thats how many fixtures MAX you can place on a 15 amp branch circuit.

Clear as mud?? Its late I didnt check my math lol
