When I put in the trellis’ for my raspberries and blackberries it occurred to me that it might be cool to have some post cap lights on the top. I wasn’t sure how bright they’d be – just thought it might be interesting in the yard at night. One possible other thing would be that if bright enough, they might discourage critters at night. I ordered some up and installed them yesterday. Easy, affordable and efficient. The photos in the dark were challenging and don’t really do them justice, but you get the idea. I think they might not also have been fully charged. Might try and get a better ‘lighted’ photo later.
