These lights offer a decent amount of light once they detect movement. However, the area in which they detect movement could be better. Also, there is only one hole for hanging these lights which makes mounting them a bit awkward. I bought another set prior to these that have lights on the sides and a second hole for hanging. I was hoping these were the same light, just a bit cheaper version. I only saved $4 on a set of six so now I wish I would have purchased the bit more expensive set but you live and learn, I guess. And these work well enough for my needs. I like being able to keep an eye on my dog when he goes outside at night to go potty when he's in the backyard beyond the reach of my spotlight and these little solar lights posted to the privacy fence do just the trick!
