Review on Upgrade Your Garden With ZGWJ Solar Ground Lights - Brighten Up Your Landscape With 8 LED Disk Lights For Lawn, Pathway, Yard, Deck, Patio & Walkway (White) by Dave Baker

They were super easy to install and look really nice in our yard with desertscaping. I had purchased a set of 8 a few weeks ago and then another set of 8 this past week and finally installed them a few nights ago. Within the 16, 5 of them are significantly less bright than the other 11. Two nights ago, we went outside later than usual and noticed that some had gone out. I checked our Ring camera last night and they all go out at different times throughout the night. They are in direct sunlight for a large majority of the day, until it starts to set behind our house. My front yard faces east. There is no shade anywhere in my front yard to block out the sun. The description states that they'll go on at dusk and off at dawn, so it is a bummer that some go out within hours of it getting dark and all are out well before dawn. Not that anyone is going by my house at midnight to see them all lit up, but by 9pm, some have already started going out. By midnight, there are just a few left on.
