I haven't any in the HT room yet. I have high ceilings in my kitchen, dinning and living rooms. I have white above my kitchen cabinets that illuminate the kitchen well enough to get snacks and drinks. Above my entertainment center, china cabinet and grandfather clock I have blue ropes that act as a highlight, but not are not bright like the white ones. I plan on using both white and blue in the HT area, as indirect lighting near the ceiling.
I bought them at Menards about a year ago or so.
