ER CHEN 66ft/20m 200LED Plug-in Copper Wire Fairy Lights - Warm White Starry String Lights with Adapter for Christmas Decor, Wedding Party, Bedroom, Garden & Outdoor Decoration

I bought several of these to decorate the ceiling of our family room, and it looks spectacular. They're bright enough to notice in a fully-lit room, and the effect is enchanting, like stars. When we want a more relaxed ambiance, we turn off the overhead lights and these light the room well enough for a chill party atmosphere. Well enough, in fact, to play cards.Obviously, that depends on the density in which you hang them. Our room is about 950 square feet, and I used 9 of these 50 meter strands.The best part is that we have them all working off one remote control and only two outlets. While you can't daisy chain these end-to-end, you can use a one-to-many AV splitter to connect many strands to one plug. Each strand ends with a 2.1mm female jack that attaches to a male 12V AC adapter plug. To cover our room's ceiling, we split ours into 2 groups, one with 4 and one with 5. I bought two "Female 2.1mm Jack to 8 Male 2.1mm Plugs CCTV Power Y Adapter" for a couple of dollars each - any 2.1mm female jack to multiple 2.1mm male plugs should work. So, multiple strands into the splitter, then the splitter into one of the 12V AC adapter plugs.We ran two outlets up above our drop ceiling, each in the center of one half of the room so that we could plug in one set of lights. Then they could be hung radiating out from the center. It took a little thought to decide on a pattern that would work well, but it wasn't hard. If we didn't have the ability to add outlets like this, it would have taken a bit more planning and we would have had to split the strands into more groups to start them off at the walls.To hang them from the ceiling, we used Command Strip Decorating Clips (17026CLR-40ES), which worked well. These lights are very light, so they didn't tax the clips, which can't really hold much weight. At each clip, I wound the copper wire around the hook. After several months, they're still holding well. I've only had to replace a few that came unstuck.As for the remote control, some of this manufacturer's sets are sold with a remote control, which has a receiver that plugs in between the 12V AC adapter plug and the strand (again, via those 2.1mm jacks). Since I wasn't sure if one remote would control two receivers, I bought two of our sets with a remote and the other seven without. I stuck with the same manufacturer and color (warm white) to get the best match in appearance, and I had no issues whatsoever. It turns out that one remote will control both sets (even hidden above our drop ceiling), though I have to be sure to point carefully at both at the same time or I can end up with the sets out of sync. It's not hard to do.As for working with the lights - I love it. The copper wire is easy to bend & shape as I like. I was careful with them, as they seem delicate, but we had no issues. There was one section of one of the strands that was not lit, but rather than send them back for a replacement we fixed it ourselves with a solder iron. I love that these are also coated to be weather proof & no concern of shocks. Though ours are inside, I would have been uncomfortable with them if they weren't.
