These lights are the best, I'm super happy I tried them. They get about 12 hours of off and on sun and provide a solid 12 hours of light on the low setting. The low setting plenty bright for typical backyard security at night or for uplighting a flag. Also, I'm in Florida and didn't have power for three days due to a hurricane and can't explain how much these lights helped. We changed them in the sun during the day and brought them in at night to help illuminate our house. I'm buying another set. I've tried many different solar lights and they all have been garbage, these are legit.The lights charge well in the sun and last the whole night. I do wish they had a white setting. There are colors of red, green, blue, teal , pink and yellow. I do like the green light on my plants. I keep a pink one on the side of my house. I used three lights (green) on my pond area as shown. I live the lights but I do wish they were brighter to light up yard area. I still recommend them because they are great also for for holiday decorating.Got these to give as a gift.... I always 'test' product before I gift it to be sure it works. Turns out I like this so much for our home that I now have to buy another one for the 'gift' as I kept this pack! It's bright and stays lit most of the night.I went out of town during a hurricane and brought these in so they would not blow away. One week after being in my dark garage they were still glowing when I came back 10/10These are the best solar lights I’ve ever had. They are super bright and stay on throughout most of the night. They don’t even get full sun all day and they work that amazing! Love the color selection and the ease of changing the colors. I bought white ones from a different brand that were supposed to be brighter and longer lasting than the colored ones and they don’t even come close to these. I wasn’t sure I’d like the colored but it turns out I love them. Don’t hesitate to buy these!They are very bright with daylight 6500K. They last all night and through the next morning on low. I am very happy with them. Only small complaint is that I wish they were a little taller. Let's hope they hold up.Already ordered 4 more. I even have one in the shade and it lights up no problem. These are great.This is my 2nd set. One of the first one did have some water inside after a year of use or so. Others still work. Happy enough to help ordered more.
