Unbelievable how well these work, the only thing I’m a little co curbed about is the part underneath here the battery is is exposed and not sealed so I’m not expecting these to last very long once moisture gets to the battery terminals - then rust will likely render these useless - but if you do install these as they’re designed theoretically you shouldn’t get much moisture in anyways. I don’t really love the geometric design of the plastic lenses as they look kind of tacky but I believe the design likely aids in producing a higher light / foot candles output. They really do put off a lot of light given their size and the cost! If you’re looking for exterior lighting specifically to light a walkway area and you have an actual structure to mount these to (theoretically you’ll need a horizontal 1” lip to mount these to ensure the solar lens is facing up so they’ll recharge during the day. I tried mounting some sideways but I don’t think they’l recharge adequately given how small the solar lens is. Lastly the brown color is kind of drab but if they’re mounted above you, you’ll only see the light lense part as the brown plastic housing is only visible on the top, surrounding the solar lense. I’ve bought a ton of solar lights in my day and for the price - these function far better than some of the expensive ones and you get 12 of these which realistically you’ll want to space them no less than every 6’ /- feet max, if you want full visibility I’d recommend installing one every 2’. These would be great to install on an exterior stairwell if installed with one on each end of every other step or every 3 steps - definitely recommend if you have a place to install them with good sunlight!!! Included batteries is also a plus!!
