I liked them. But they don't give much light or last long. A plug to supply power would be great and I plant to carve that in using a USB like supply.

PRO: Largest Solar Cell panel of all I could find. This helps charge faster and/or in lesser light
PRO: Largest battery of all I could find. Will illuminate longer - IFF it gets fully charged by solar cell
PRO: Bright enough for brown environment when fully charged in direct sun.

NOTE: Full sun pictures are pre-charge direct sun facing - importantly - before installation.

The installation is entrance landing, steps down to lower floor, to landing, to deck.
This side of the house gets minimal full sun and the steps down are to the North further minimizing sun.

CON: Not bright enough to be useful when installed on the shaded steps - even after a full non overcast day.

3 of the 4 pictures have a mix of just installed (so fully charged in sun) and yesterdays (so full day of shade).

Note the camera adapts some - so the steps look brighter than they were.
But it is a good example of how bright the lights are IFF they can get a good charge. I was hopeful.

Note in particular the single light picture. That is a shaded side single light an hour or two after dark. Note you can just barely the light itself. This is the same light that is in lower right of the full landing picture included - with some camera adaptation to light you can barely see the shade-charged ones and in particular how that one doesn't illuminate anything.

Summary: These are great but ONLY IF you can install them so they get full sun. Not shade. Absolutely full sun for a good part of the day. In particular don't use for safety/steps unless you can do that.

I did think these were the best I could find that weren't wired.

Recommendation if shaded install (including say steps facing away or shallower angle) is to go straight to a wired installation.

I have had these lights up on my deck for a couple of months now. This was my second time purchasing. This time ONE of the lights has stopped working. Do I have any recourse?? Is it possible to buy ONE replacement ,ight??

What great little lights!
They came with a full charge so we could test them right away. Easy to assemble (if you can plug a lamp into a wall socket, you've got this!), and easy to mount to balcony rails with two provided screws each, these small-yet-powerful solar lights put out just the right amount of Illumination. Nice 'mood' lighting without being obnoxiously bright... for those of us who prefer 'dark skys'. As an added bonus, they perfectly match my homes wall sconce lights!
I ordered another set for the rear deck!

It work when it is sunny better then other brands.
