I'm in the process of adding 2 ceiling fans to my covered patio. I planned on using 1/2" EMT and compression fittings but wasn't sure which type of wire to use 12AWG THHN or romex 12/2.? If both are acceptable which is easier to work with?

Hello all. Hopefully this is the right place to ask, but I am trying to understand how to install lights at the peaks of my gables on my home. As shown in the example picture below (not my house, [url=https://www.luminatedlandscapes.com/outdoor-lighting/peak-lighting/]credit[/url]): [img]https://cimg3.ibsrv.net/gimg/www.doityourselft.com-vbulletin/1017x515/capture_ac22bfbe22b641d4ae352a907cbe18a7c2bf87ea.png[/img] I am looking into using these [url=https://www.philips-hue.com/en-us/p/hue-white-and-color-ambiance-lily-outdoor-spot-light/1746730V7?&origin=p65588387660&pcrid=538556677117%7cmckv%7cp65588387660_dc%7cplid%7c%7cslid%7c%7cpgrid%7c124092928245%7cptaid%7cpla-1395454601962%7cproduct%7c915006001101%7c&gclid=CjwKCAjwtfqKBhBoEiwAZuesiEW0uZdt3e5zmuii_Ocf2BAsMajQDcJg3iUDHp6P-NP9xchhCr8SpBoCix8QAvD_BwE&gclsrc=aw.ds#overview]Lily Phillip Hue lights[/url] so I can adjust the colors year round. I am struggling with how the professional installers generally run the wire for these. My house has an attached three car garage with two gables, and then one gable at the front entrance of the house. My house has vinyl siding (which I am hoping is an advantage). I'm having a hard time finding information on installing lights in these specific areas. I saw some references to installers installing at the gutters pointing up, and then feeding the wire inside the gutter and to the down spout. First, are the lights I chose a good option? Any downside to using these specific ones for the area being installed? Second: My original thought was to drill a hole in the soffit at each peak and lead the low voltage wires into the attics... two coming in at the garage attic, and the other one coming in at the house attic, and then lead the house attic wire into the garage attic (drilling a small hole to get there where the two meet but have a plywood barrier). Then just meet at the splitter, and plug into one of my garage door opener outlets. The soffits don't have any backing plywood, it's just the thin vinyl or aluminum material used to cover it. ...But, looking at the way some of these other outdoor spotlights were installed with keeping the wires external, can I somehow avoid drilling into the soffit and store the wire along the eave some how without being seen to bring it to ground level? Can I bring the wire behind the siding? Taking this route (if possible) the area I feel might be most difficult is the large gable at the garage, it is setback behind the front gable and the wire would have to pass over the roofing material some how. Below is exactly how my garage gables are (the circled area by the down spout has an area of roofing, and the eave doesn't travel all the way to the below eave): [img]https://cimg2.ibsrv.net/gimg/www.doityourselft.com-vbulletin/430x353/capture2_e61cd907938029d8ae033ea8abc0e8cf0573699d.png[/img] Navigating the wires externally would be more ideal, to making holes into the soffits, and passing wire around the attics, and it would allow me to avoid walking around in the insulated attic. Hopefully this makes sense to those of you who have read this far. Any help or suggestions I would greatly appreciate. Thank you!
