Installed it about 2 months ago, winter here so not great daylight, but it works well all night. I don't understand the bad reviews about not much light, its a solar LED light. plenty enough light to find the right key and open a door without tripping over the garden hose you forgot to put up. Lights up about a 10 - 12 foot area. I wouldn't try to read a newspaper with it, though you could prob read the first page before your eyes start to hurt. It does stay on in dim mode from dusk till dawn, enough to see if somebody or something is wandering around near it. Mine is mounted about 7' high above a shed door, it gos bright when I get within about 4'.
