Question: I have these lights for 8 days, and they are not working....did I do something wrong?
Document: Love the different mode settings especially the fade in and out it's pretty cool. They stay lit up a good 8-10 hours from a full day of sun. The price is excellent, I have no complaints with these lights.
These lights are FANTASTIC!!!! They do NOT look &#34;Christmasy&#34;. I've had them attached to my dock and they are bright and twinkle from dusk to dawn. I LOVE them! I highly recommend them and will buy more as gifts. Great price, very durable, have been working great for 3 months so far. Beautiful colors! !
Utter awesomeness!!! These little lights are bright, colorful, and 200 of them drape 4 times over the trellis in my backyard making quite a display come sunset. My yard if full of all kinds of solar lights and these are by far my favorite. I've watched all 8 modes and they're so much fun! But mostly I leave them just "plain on" for fear my neighbors are going to have me hauled away due to the colorful glow emanating from my backyard every night.
These lights work well when the days are sunny. When it's a grey and rainy day, the solar charged battery doesn't last long.The solar power concept is well executed, but the wiring for the LED's is of such a light gauge that you really have to be careful because standard manual staple gun will break the wires (yes, that's experience talking). When I put them up next year, I plan on wrapping the wire with electrical tape, leaving a tab, then stapling the tab to the handrail.
And the fact that they're solar means I don't have to worry about wiring, electricity bills, etc. As long as there's some sun during the day the lights come on at dusk. I highly recommend these for anyone looking for something fun and happy for their yard. I'm 59 and IMNSHO you don't have to be a kid to enjoy them, maybe just have the heart of one!
I tested these for several days before I was going to put them where I wanted. I'm glad I did because they always burnt out within 3 hours of sunset. I was hoping for more like 6 hours. I returned them.
the first use was good. After being outside in the cold and snow they did not work. I brought them inside and they began working. I then used artificial light to charge them and discovered 2 hours of artificial light gives 2 hours  of light. I became confused,since they said they are to be used outside only,but they did not work to my satisfaction. I contacted the company . they were somewhat helpful,but I did not want to pursue  the issue any longer.
Long strand. Beautiful.Has lasted through rain and a couple months so far.I like the colored lights. I like the fact they flash. Very pleased
They worked great after I realized about the little things under the solar plate had to be pressed!Sometimes I can be such a dummy...I love these lights!I now have four strings of the lights from this company.......have a great spot for another string.....they are so very lovely!
No extension cord running from your house to the lights.Different modes so it's never boring.Solar powered, no hit on the electric bill.I bought one, loved it so much, I bought like 6 more!Weatherproof, so it's worry free.Luv it!! !
