All the kinds I've installed before were spec'd / provided.Now I have the opportunity to recommend mfg./type/style to a h/o.What's the concensus,if there is one on low volt vs. line volt; halogen vs. fluoresent, puck, strip,etc.; keeping in mind they want minimum switching to avoid more openings in future tile backslash. BTW, they also want over cabinet lights for 'accent' and I'm leaning to rope lights for that.Thanks, Dan.
