I use a advatek pixlite 4 mk2 but falcon controllers are the way to go with meanwell power supply.
This time of year would be hard to get a controller but there are other options I recommend reading the ACL 101 manual
I started this year and made my arches with 25mm electrical conduit. Used a bench drill and made a jig same jig that Lawrence's lights made and drilled 13mm holes every 50mm and installed 12v bullet pixles. Was happy with how they looked.
