Question: how do you change batteries?
Document: The lights are a great value. You will mostly have to change the batteries or charge the ones that came with the light.
Water bills up inside light lens not sealed. Battery to hard to change.Just not what I was looking for sorry
Flimsy, batteries didn't last long. Not happy with this buy. Wasted money. Don't buy this item, get something better please.
I will have to check to see if batteries need replacing or what else could be wrong, but they don't work. They lit up the first night and nothing since then.
the light to not stay on long enough go off in 2 hours had to replace batteries one light does not work at all very unhappy total waste of money does not give enough light when they do work
In addition to all the negative reviews that people have left about this product, i'd like to mention that they come with 200mAh batteries. That means that the lights' barely-existent light only lasts about 3 hours on a full day's (10 hours in Virginia's sun) charge.Do yourself a favor and get a different brand.
I replace them with 2000mAh models as soon as I can as they hold more power. The solar panels used in most outdoor lighting is inferior to anything but NASA quality stuff and never fully charge the batteries because of so. You are better off charging them inside with a wall mounted charger than to let the solar panel do it for you. The LEDs used in this model are decades old technology as well.
I have been experimenting with scads of solar lighting products over the past few seasons since my older neighbor put in a pool. I have been relegated to 'the light guy'. I saw these on AMZ but the guy I do this for bought then at a big box store. I have run across some cheap ones which I already commented about but these take the cake as far as cheap. First, any batteries that come in solar lights are going to be the cheapest and poorest performing junk manufactured.
will eventually be the final verdict and do not recommend them for hot climates or anything else than as toy with a limited shelf life.
was a little disappointed that they don't put out much light but then they ARE only solar,  anyway I have one pointed at my front door and various areas around the house, they do what any solar powered light should. so I really have no complaints. BUT if its cloudy of course they wont be as bright because they need strong sunlight to give their best brightness
Answer: yes
