Plenty of good suggestions already but I for the under cabinet kitchen lighting (16’ strip of cob LED) I installed a few years ago I just used thermostat (18/2 I think?) wire to run the gap between cabinets. Just don’t make the same mistake I did and use the cheap solder that comes with the kits, it was such a frustrating experience until I bit the bullet and bought some nicer stuff, made the process WAY easier
Regal and Aura both. I was a Sherwin Williams fanboy on my own projects until I started working with a guy who tries to only use Ben Moore stuff and now I’m sold. So worth the cost
