Review on BrizLabs Christmas String Lights, 270Ft 800 LED Warm White & Multicolor Color Changing Christmas Lights With Remote Timer, 11 Modes Xmas Tree Twinkle Fairy Lights For Party Indoor Xmas Tree Decor by Ron Damndjperiod

To answer the question I could not find a clear answer to.YES, the 66' strand is perfect for a typical 6ft tree. Not too bright. Not too dim. Just right. I ran a 66' strand on the outside face of the tree beginning at the base up to the top in upward spiral bands 5-7" apart with enough left after to run down the trunk inside my artificial tree back to the base and then back up the trunk again to the top. Mesmerizing displays included. Not typical lights. They come on a thin 3 strand copper-looking wire that can be a little hard to deal with but definitely worth it.
