Nice bright light
Color: Cool White (Cuboid), Size: 8 Pack
Purchased for a gift. They arrived on time and packaged well. Installation was easy and the lights are very bright. They seem to be made well and stay on most of the night. Would purchase again.

Nice solar lights
Color: Warm White (Cylinder), Size: 8 Pack
Each of the lights is well made. Installation was easy, adding them along a dark walkway took only a few minutes. I installed them in the morning and had charged enough to provide light to the area. Look very nice and a good value for the money. Happy with this purchase and would buy again.

Bright solar lights
Color: Cool White (Cylinder), Size: 6 Pack
Great look. Cool white lights are bright and lighten my dark walkway. My only con is that the solar panels on the flat top turned white after a few months from rain/water sitting on them. The lights continue to work well, despite the tops being 'milky' white.

Gama Sonic Solar Lights: Built to Last and Guaranteed
Number of Items: 2
These lights are nice and bright and stay on all night. I have other Gama Sonic solar lights also. One of them, which I didn't buy from Amazon, had a problem so I contacted Gama Sonic directly because they have a 2-year warranty. They responded immediately and I got it fixed and now I'm happy with it. I will keep buying their solar lights because they make good quality solar lights and have a 2-year warranty.
