I bought three packs of these for my front walkway. During the summer they operated acceptably.
Now that the days have grown short and the New England gloom has descended on us they last about an hour after dusk.
This is the second type of solar light I have tried. I am going back to hard wired lights.
I think these lights are extremely bright..although i did have one of the stakes break when I pushed it into the ground. However, instead of returning it I called customer service who said since it was item it wasn't in her system yet, and she would investigate and send a new stake. That was 2 months ago and I received neither the stake or response fom customer service. In the meantime I noticed there is rust around the solar panels on one of the lights. Needless to say I will be returning them today. I thought based the the weight of the lights they were a great bargain for the price. I guess you get what you pay for.
I bought a pair of these lights. One has been wonderful, but the stake broke when I pushed it into the ground. The other light burned for only a night or two then went dark. I was going to change the battery, but the battery is an odd size, not a AA. I have not found a matching battery.
