Basic question about adding more lights.

Hello! I have a question regarding adding more lights. My basement is very dark and there's only two lights on the one side, which is turning into more of a finished basement on this side (other side is a workshop, laundry, etc.)

Question is this. I want to add two more lights to the existing two in the ceiling. I did a very basic drawing to tie in a visual. Also, I did some reading about the overall load of the circuit. This circuit is on 20 amps, so based on some reading I did online in conjunction with what's connected to the circuit (just seems like it effects a handful of lights, no outlets at all), it seems like I have some headroom. But I do understand I have to do some more wattage calculations to make sure I still have the proper headroom needed. This question is more about whether or not I can even do what I'm brewing up in my mind.

Here's the image:

Red dots = existing lights.
Black lines = existing wiring.
Yellow dot = light in other side of basement that the lights from the finished side are connected to.
Green dot = electrical box.
Blue dots = new lights I want to install.
Blue lines = new 14/2 wiring I want to install.

Can I add them in this demeanor? I just wasn't sure if I can branch off quite like this.

Thanks for the insight!

If the circuit is 20 amps you cannot use #14 wire. You need #12.

Other than that it will work as long as the boxes have enough stated capacity for the new cables.


Answers based on the National Electrical Code. Local amendments may apply. Check with your local building officials.

Thanks for your quick response! I pulled this up on my phone when I was in line at the hardware store. Had to run back because I had no 12-2. Saved me a trip! Thanks again.
