They r very tiny, so not much light coming out. Nica as a decoration, but did not light up kids playground as we expected.We put these outside our camper- they look great. 4 stars because we had one strand out of 3 that stopped working.I tested these lights before installing them, and even charged them on the ground for a day. They seemed to be working just fine. It took me two days to hang them on a pergola, and the lights never came on after the installation. One of the sets worked, and the other one didn’t. I assumed I hadn’t pushed the button on the control to charge them and had to climb up the ladder once more and push the control button, but nothing changed. So I had to undo the whole thing and take it down. Even tested once more inside the house to make sure it doesn’t work. It didn’t. I had to send the whole thing back and request a refund, which I received immediately.Edit: I changed my star rating and gave them 5 stars for 100% customer satisfaction. The return process was easy and flawless.I like these lights, but be careful some raccoons like it too , they cut it off many times up to the middle string, but first half of lights still working. I was pretty surprised.I ordered it again. Work and look like expected.After night hits and they light up, they only last for about 4 hours. And that's straight sun change all dayVery niceAt this time there’s really nothing to dislike about the Product I like that it’s solarSuper cool
