Review on 24-Pack Bright White Solar Driveway Lights With Screw - Waterproof Wireless Dock Lights For Path Warning, Garden, Walkway, Sidewalk, And Steps - 6 LED Solar Deck Lights By Happybuy by Bryan Gallardo

We saw these path lights at a resort in South Africa, and we were quite impressed with how effectively they lit the driveways and walkways around the grounds. We need similar lighting on the periphery of our somewhat tight front circular driveway here in California, with the goal of helping visitors negotiate the driveway without putting a wheel into the landscaping. So, we ordered 24 of these Happybuy units, which arrived about a week later.This type of light is typically positioned to send light across the pathway. In our case, we positioned them 90 degrees to the typical orientation so that the lights illuminated the edge pavers. (see photos) This works quite well for us, leaving little doubt to visitors as to the location of the driveway edges.Suggestions:After some thought, we decided to position the lights temporarily for a few days to make sure we had the right locations and orientation. This also allowed us to make sure the solar cells would get enough sun during the day to charge the batteries. You should also think about how shading varies during the year. In the overhead photo of the driveway, south is up, meaning there are times during the day when sunlight is more limited. Still, even in winter, we are getting more than enough sunlight to have the light work into the middle of the night. When the lights get a full charge, they operate all night!How the lights should be anchored will vary based on the material on which they will be mounted: concrete, stone, wood, etc. My driveway uses pavers, so I chose to use pre-lubricated ¼” X 1-1/4” concrete anchors. I used an impact drill to create a hole about 2” deep. I then used an air bottle to blow dust from the hole to make sure the screw would not create excessive spreading forces. A socket wrench tightened the screws, using a screwdriver for the final tightening force.A good idea is to place the lights where wanted, then mark only one of the two mounting hole locations. This is especially important if the lights are to be mounted on concrete or stone; getting the drill to penetrate exactly on the marked point is sometimes difficult. So, drill the first hole, then position the light over the hole using a hand-inserted anchor. Now mark the other hole, drill and complete the installation.Some of the early reviewers on these products complained of early failures, and my hope is that I will not see these problems. The units seem very well made.UPDATE: At the 14 month mark, two of these lights have failed, and several other appear to have water penetrate to top cover. I suspect these will also fail. They really do the job well, so I will order a few more in hoped that they have solved their problems. I have reduced my rating to average, as a result.The new units have arrived - I bought the 12-pack - and I am looking them over. There do not appear to be any design changes to make them more weather resistant. Upon investigation, I found that a total of five of my original units had failed.Here's a mystery: one of the units that failed to light was removed. While I was looking at it on my desk, I changed channels on the office TV. When the IR signal hit the light, it turned on. It stays on for about 90 seconds. It repeats this reliably!
