Question: how long will thay run after dark
Document: They don't work well at all. If they do get sun, they aren't very bright and don't last long. Don't waste your money on these lights.
They are ok, not great. Not very bright and of course of the less light days of winter they don't last all night long.
very cheap plastic make and it don't work. The battle doesn't hold it charge. Run out so fast and solar don't work..Don't buy this ! !1
I bought 2 of these for the long side of my house where the porch lights do not shine. Just enough to shine between the bedroom windows. I'm very satisfied.
The solar lights arrive before the arrive due date came 7-22-13 I am going to use them when we put our American flagSo it can have light all night long. The package was done excellent. Thank you.
I installed them 2 weeks ago. Worked well that night, on nights after cloudy days, and rainy days. Easy enough to install on a gutter, but did not fit too wellon a metal 4 inch gutter- the part that screws into the gutter is not long enough to grab over the edge when the little foam pad is used to protect the paint on the gutter. I had to install them without the pad. Also, the screw to tighten the hinge which determins the angle of the light was difficult to get tight enough (oddly, on just one light- the other was fine) so it is not held firmly to shine the light out from the gutter to a place a few feet from the ground under the gutter.
these are ok, but not that bright and the charge on them only lasts a few hours. If there is wind it will move them too
just the right amount of light I needed around my house, easy to install. can also be installed on the fence line.
is not very bright
We wanted to add some lights over our front and back doors. These solar lights fit the bill. They clamp on to the gutter, so you can position them where you want them. We put two over each door, which was good because the light they produce isn't very strong. Of course, how much sun each light is exposed to affects that, too. We are satisfied with the way they are working for us.
