It's not to big neither small, just perfectVery easy to install. You cannot adjust motion detection range and the factory setting is short. Not very bright at all.Only 4 stars because the first set of lights was defective. The 2nd set works perfect. These lights advertise 3000 lumins, much more than comparable lights in this price range. Overall, I am happy with my purchase.One lamp worked. The other did not. Light goes off exactly 15 sec after turning on. Our dog is 13 years old so there’s a lot of jumping & hand-waving that goes on for her final call! No options to increase lighting time. My bad…should have done a better job of reading light details. Thus the 3 stars!I was skeptical not knowing how much light it would give off, but this light is absolutely perfect! Lights up the whole side yard beside my garage! I specifically needed a solar flood light with a cord for the solar panel, because the side of the garage I installed it on is opposite of the morning sun, and trre block the evening sun. So I ran the panel to the backside of the garage, and put the light around the corner where I wanted it, and it worked perfectly!This lights are not that bright and are made very poorly. They do not light up a lot of the place as described.Not what I had expected. Easy to install, very little light emitted.Light is bright but only reaches about 20 feet!
