A lot of it depends on what your local electrical codes are. Where I live you can’t have more than 15 lights on a single circuit. But theoretically, each bulb will take .625 amps, so you can take your breaker size (amperage) and divide that by .625 then subtract that value by 10% and that will give you that maximim load your circuit can handle.
If you’re talking about 120 volts AC, 75 watts is about 2/3 of an amp. So a 15 amp circuit could handle 22 of them. But you have to add the current the fans and everything else on that circuit draws too.
It’s more of a question of how many amps can the circuit handle. Depends on the draw. I assume there are no fans because you called them can lights. As a rule I never put anymore than 8 or 9 lights or receptacles on any one circuit.
The recessed cans are usually wired with 14-2 romex 110v, which is rated to carry 15 amps or around 1500 watts. So do the math, 20 times 75 equals 1500. Why would you want that many liights on one circuit for. Selling Christmas tree outside under the table during Christmas. If so, you can’t write off the additional electric usage. Use heavier rated wire like 10-2 at 30 amps and sit down and light up half the town, DUH like 40 bulbs. Want to go higher?
You can also switch to screw in fluorescent bulbs, save money and not worry about it. A fluorescent bulb draws about 15 watts and put out the light equivalent to a 75 watt bulb.
just to piggyback the flourescent bulb idea……. dont do it if your cans are on dimmer switches, these newer bulbs hate that. they flicker at low settings and eventually burn out a lot quicker… fyi
