Brightech Ambience Pro - Waterproof Solar LED Outdoor String Lights – 1W Retro Edison Globe Bulbs - 27 Ft Bistro Lights Create Cafe Ambience in Your Yard, Pergola - Soft White

Being technical by nature this review is aimed at people who want details not described in most of the other reviews. I bought two sets of these light for a new, backyard pergola. Having read other reviews I was fully aware that these lights would not be as bright as hard-wired (110v) string lights. They are intended to provide low-level, mood/conversation lighting under my 14 x 17 pergola.First, it’s important to point out that the advertised length of 27 ft. represents the entire length of the product. More than 1/3 of that is the span of wire between the solar panel and the first light, which is 9.5 ft. I will attempt to include a diagram (picture) with this review that shows all the measurements related to this product. Also, the advertised distance between each bulb is 20 inches when in fact is 18.5 inches. There are 12 bulbs and total distance from bulb 1 to bulb 12 is 17 ft.Each bulb socket has a small hole on its end. The hole makes it convenient for hanging the lights and using an S-hook works really well. The wiring seems pretty solid and the quality overall is nice. The biggest unknown for me living in the hot desert will be seeing how well the product stands up to intense sun and heat. The first fail point is likely to be the battery. The advertised battery is a single, 1500mah, type 18650, 3.7V. It’s sealed inside the solar panel. I’d prefer if it was replaceable although there is male/female twist-connection between the panel and the sting of lights so at least the solar panel/battery unit can be replaced if need be.To mount the solar panel, which does not weigh very much at all, you have the option of using a stake (for ground mounting) or a large clip. The clip is plastic, fairly strong and well built. Although it does fit on my 2 x 4 pergola framing (actually 1.2 in.), due to the potential for very strong winds, I plan to forgo both of those mounting options and will develop my own to attach the solar panel to the top of the pergola.Overall I'm happy with the quality and the product works as expected.

I bought 3 strands of these lights a little over a year ago to string through Shepherd’s hooks around our fire pit. They look beautiful & sturdy in daylight and have a lovely, warm glow at night. They stay lit for at least 5 hrs after sunset. At one point earlier this year, I noticed one of the strands wasn’t functioning and made a guess that it was the solar panel rather than the lights that wasn’t functioning correctly. I tested out my hypothesis by hooking up that strand with a panel I knew was working—and they came on perfectly just as I had expected. I contacted Brightech to ask if I could buy a replacement solar panel, and not only did they promptly respond, they sent me a replacement solar panel for free, stating that I was within my warranty period (I didn’t even know that at the time!).Flash forward to just over a week ago, a tree fell on the light circle during a storm. Amazingly the string is so strong that it just slipped off of the Shepherd’s hooks and fell to the ground with the crashing tree rather than tearing into pieces. The impact caused several of the bulb’s filaments to break, but the rest of the string continues to function. The solar panel on that string also appears to be malfunctioning as the light only flickers dimly now. I contacted Brightech again just yesterday and they have already replied to tell me they are happy to send replacement bulb filaments and a new panel so I can get that string back to its top-notch quality.I have never experienced customer service on this level of excellence before! I am so very pleased. They have certainly made me a return customer (I just bought another string to hang along the garage near another sitting area). Many kudos & thank yous, Brightech! Keep up the great work.

We are extremely pleased with these lights! They do exactly what is stated and what we wanted. They turn on automatically at dusk and stay on for at least 6 hours; they provide a lovely amount of illumination over some chairs in our garden. You wouldn't choose them to read under, but they're perfect on nice evenings when its pleasant to sit outside.The build quality is excellent and appears to be very sturdy, including the water-tight screw connector between the solar/battery panel and the light string. The lights themselves and the connecting cable inspire trust without being too heavy looking.The provided instructions are simple but very accurate. As noted on those instructions, these only charge when the panel is turned ON, then we just leave it in that ON state permanently. The mounting options are quite good, except the spring clip only allows east-west orientation of the panel. I've offered a suggestion to BrighTech how that could be improved. It was pretty easy to figure out a very solid option that would give the preferred south-facing orientation in our situation.I was impressed with how quickly BrighTech responded to my suggestion and a question. If we decide to do a multi-colored strand for holiday lights, I will be very confident if it comes from BrighTech.
