Question: Are screws included?  What type? Can they be used in a concrete wall?
Document: Due to the small amount of light produced by this lantern I would not recommend this be used to help get around at night.
The lantern still charges well even with the lack of sunshine we've been having. But again as stated above, this lantern should be used for display purposes only and not used as a source of light to get around at night.
It doesnt look cheap. Ive been using it for a few months and its still working great. Shines all night and its bright enough to see from across a 20 acre pasture. It even got really banged up in a storm, the glass did not break and it still continued to work. Theres real glass in the panels. We live in an offgrid cabin and used it as a front porch light. I love it. I would order it again and recommend it to a friend.
well packaged real glass! not very bright, but what I wanted, I bought 4.Sized like a real light for out doors. Comes with mounting screws and hanger, just wish It could mount up right off a porch rail.
I bought them to beautify my front gate posts without having to run wiring and they do that well.3. So far they have held up to several thunderstorms,4. Like I said, the included batteries are rubbish...and it's a little finicky to change out. You will need a small screwdriver and some decent NiCD's.OVERALLI'm very happy for the price. Customer service (amazon prime covered) saved the day.
These are real metal and glass lights. The factory batteries are terrible. They are 600 maH AA batteries and don't do the lights any justice. I replaced the batteries with 2700 maH AA batteries and the difference was light night and day. I placed a small round dome type automotive stick on mirror inside the bottom of the light to reflect the light even more and it made it much more reflective and brighter.
they look more expensive than they cost. well made, and the real frosted glass gives them a rich effect at night
these lights are beatiful even my neibors love them and they do burn all night they are still on when i get up at 6 am in the mourning
Works well to light up back patio at night. No light switch to turn on, just Az sun from daytime.
Works just fine, but this light is DIM. do not use for actual illumination . It needs a few more led lights and clear glass instead of frosted
Answer: no
