Lots of light from solar, fully adjustable on app and can be used to activate other Ring products. I love them, got 4 for a 12 step staircase and only used 3 due to the amount of light they put out. I decided to use the fourth on on the side of the deck to light up a walkway. They charge up 100% and so far have never not worked when needed. I plan on buying more for some lighting on a patio!
