Hello, I'm new to this and a little confused. Is ELV required for any LED light control ? Are LED necessarily low-voltage ? I'd like to control a set of ~6 recessed LED (i think GU10) and this (https://www.sonnemanawayoflight.com/item/Stix/2770.03). For the Stix, it says ELV in the specs so I have my answer.What about the recessed LED ? Can I use the non ELV which is cheaper ? For 3-way control, 1 will be a fancy switch with the little led dot on the side but the other has to be a pico right ?Thank you guys !
