I purchased one order of these lights to hang in my livingroom window for some gentle, ambiant light. I had the sheer curtains already there looking out onto our backyard. There are several different settings for the lights (still, blinking, fade… etc). These are just the right length for a window about 2 doorways wide. I was worried that the lights might heat up causing a fire hazard being next to the sheer curtains but the lights themselves do not get hot, or even warm. There are 10 strings hanging off of the main string which are quite long. The plug in cord is long enough that it can reach the floor from up near the ceiling,a nd then some. I will most likely be buying another set in the near future.
