Can Lights per Circuit

Technically, you can install 13 outlets or lights on a 20-amp CB, but you can only put ten lights per circuit due to the 80% rule of maximum continuous load.

How many can lights can be on one circuit?

There is no limit to the number of lights on a circuit. The load of the fixtures is what determines how many lights a circuit can accommodate. A conventional 15A circuit can have up to 1400W of lighting loads connected to it. A 1400 Watts lighting load can accommodate one 1400W fixture or fourteen 100W fixtures.

Can you put more LED lights on a circuit?

The limit is 12, unless you are installing devices that have a known load. In the case of a LED light which is hardwired in, or a smoke alarm, you can put as many of these devices on the circuit providing you don’t exceed the 80% load.
