I was very excited to receive these, and immediately put them on the garden beds. The first night they were very bright and stayed lit all night. However, as the days continued, they dimmed, and now barely light at all. I understand that the sun is not out, etc. but I have other solar lights in the back of my house and they do just fine. I bought eight of these - 4-2 packs - so I’m hoping when the sun is brighter, they will work as they’re supposed to. So, they SHOULD be great … but we’ll see.
