Review on ROWSEN Detector Controller Recreational Waterproof by Sean Perry

The description does not include size or dimensions. The photos in the description, obviously photoshopped, make it look a lot bigger than it really is. I expected the light to be around 6-8 inches wide or maybe more. The light is actually about 4 inches wide and 3 inches high. A little bit small. However, he does what he says. about 10'x10' is really bright, and about 10' there is less light in the extra space in all directions. The light is bright, I'll give it to him. Because it's motion detection and doesn't stay on all the time, the battery lasts a while. I haven't used it to try turning it on for many hours at a time to see how long the battery lasts, but I would estimate at least 1 hour of full brightness. But that's a guess, I think it stays on for 1-2 minutes per "motion detection". I'm deducting 1 star for cheating on its size, but it works as advertised so I can't hit it too hard.
