I have the holiday coro tune to sing that takes around 450 lights. I use regular clear incans, but I dim them to 50% to cut back on electricity use, and they still look fine at the street view. I planned to replace them with smoothside M5 LEDs that I bought at Big Lots last year but never got around to it. One more little project for this coming season. Incans will be the cheapest for you to use, but I am amp challenged so anything I can do to eliminate all the power that incans use helps. My goal for this year is to convert my mini trees to LED using the lights that were replaced by nodes. And hopefully replace my incan arches with flexstrip arches. Soon as I get back from the Academy lighting takes the highest priority for me.
