Dense enough to make a nice curtain effect. Love that colors can be changed. However, on the 'Christmas colors' can blink...which others did also. I use them to essentially light my porch at night. Looks very attractive and fun to see...Great addition to the outdoor porchWhat are these for our a Christmas display But they tangle easy and any wrong movement it pulls the wires out of where they are plugged into the lights.My hope was to use these as banner sashes from a balcony. Wrong. Light wind and they are all tangled . No remote. Operated from fob on the lights.Outdoor decorations. Easy enough to install and the neighbors like them as much as I do.Lights add nice effect at night. Brightness is better than expected. Different light patterns are a fun feature! Lights were easy enough to install although if not careful they will tangle abit. If hung outside and there is a heavy breeze the light strands do tangle.I purchased 6 sets of lights earlier this year. I checked them when they arrived to make sure they lit up and all was good, BUT, I of course, didn't use them until I began decorating for Christmas. I ordered two sets of reds, two sets of greens and two sets of white. Only about 3 1/2 weeks after installing them on my hedges outside, one set of green and one set of white stopped lighting. My husband and I took them off of the hedges and spread them out to see if we could find the problem. We did. On both sets, several wires had come out of the little "clips" that wire the light to the wire. We attempted to push the wires back into the clips, unsuccessfully. We tried taking the clips off and splicing the wires, unsuccessfully. Nothing we did would make the lights work again, so we just threw away. What a waste of money.Nice looking but fried and stopped working during the second Christmas season.
