Hi expert,
this is my first project of trying to add more light to my backyard. We have an outdoor light right at our backdoor which is under a patio so our whole backyard doesn't have any light. I would like to use this light wiring to add a about 3 additional floodlight. I've been reading about wiring so if I am not mistaking, I need to run the romex wire to each of them from the existing light. My worry is since it's outdoor, I need to make sure it's water proof somehow. the mounting place would be exposed to rain. What is the bestway to approach this? TIA.

 

Welcome to the forums.

There are two ways you can wire it up. One is to use UF cable. It looks like standard indoor NM (romex) wire but is usually a dark gray and is specially made for outdoor installations. The other method is to use a conduit system. That could be PVC or EMT (thinwall metal tubing). The conduit system uses individual strands of wire as opposed to a single cable. In some applications it looks neater, installs easier and straighter.

The actual connection to the light fixture could be a little tricky.

Posting a picture or two of your setup and back of the house would help us guide you better.
