How many lights can I put on a circuit?
I found a bit more information and thought I would update this. The code has changed and I believe specifically section 8-304 of the most recent code has been amended for situations like this. 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. This applies as long as you have no points on the circuit (such as receptacles) which would be an unknown load (since you don't know what someone is going to plugin). The moment you add a receptacle the limit drops back to 12. Hope this helps!
