I have a customer who has purchased Kichler u/c LED fixtures. They are low voltage with a remote power supply. I'm not too familiar with these products, is something like this usually wired with individual leads from the trans to each fixture? A few of the part #'s are as follows Kich 12303wh, 12305wh. Also, would switching basically be providing power to the trans when you want to turn them on via a conventional wall switch, or having the trans hot all the time? Thanks for any tips.
