These lights are quite bright and have a wide angle of illumination. The solar panel charges the battery during the day and a photo sensor turns it on automaticaly at dark. I would have given them a 5 star rating except the battery capacity could be better. They are over rated at 2200 mah I have only gottten around 1000 mah when I tested them. I plan to replace the included 18650 to a higher mah, 5,000-6,000 That should hold charge longer and stay illuminated all night. So far they have only stayed on about 5 1/2 hrs continously. Average has been 2-4 hrs. Over all I am happy with these.
