I have had this product installed for several weeks now, installing about 30 lights to mark the edge of our driveway.We have a pair of large culverts under our driveway, which cause a significant crest and creates a hazardous drop off, going down the driveway, conveniently right where the driveway tapers to its narrowest. These lights have helped to highlight those edges at night and make the driveway safer for us and guests while providing a beautiful accent and ambiance. Additionally, marking the edge of the driveway helps to protect the sprinkler heads for the irrigation system from inadvertent tire damage from vehicles dropping tires off the driveway.These lights have a pre-installer selection abilityto offer a warm (amber White) or cool (blue white) white option. I bought these specifically for the warm output to match our current lighting and future landscape lighting intentions, and they look amazing. The light output performance is perfect, not to bright to be obnoxious, but enough to be perfectly visibile. The preinstalled batteries have had no issues charging up in the day hours and have had strong output all night until sunrise in the summer months of North Texas with no visible decline of output in the predawn hours. I had concerns that the radiant heat and hot summer Texas heat may damage the rechargeable batteries in these units, but so far so good!Purchasing was easy, shipping was fast, and they were about the best value I could find, but without sacrificing the best appearance IMHO, offering that 360 degree output with a spoked look.They are low profile and not overly large in size, about the size of an adult large hand. Given their size and design the lights offer versatility in application including decking, or steps, sidewalks, porches, or used in vertical applications for accent lighting.We have had no issues with durability or any breaking to date from vehicles or mowing equipment. 32/32 lights worked 100% out the box, and are still working nearly a month later (30 are installed/2 spares in storage).Setup was easy, I simply placed them all out on the driveway for the day to receive a full charge. The next day, I turned on all the units and oriented them on the driveway to verify placement and look. That night I verified the 3 place power switch was switched to the correct color temperature on all the units before securing them down. I made final adjustments at night and verified the look, then simply used a caulking gun with Loctite PL Premium Max Construction Adhesive (a grey color that matches the frame of the lights and is neutral with concrete). Placing a dab under each mounting ear and a dab in each of the two hollow voids in the bottom. This anchoring adhesive has been holding the units perfectly secure to the concrete driveway, without the need to drill permanent holes or penetrations for moisture. I did bump the deck of our commercial mower against two of the lights about 48 hours after securing the lights down, and the units broke from the adhesive dislodging them, but the lights were not damaged whatsoever and were easily reattached. These lights were some of the first I secured and I only used two dabs not 4 on these, to secure and they were small amounts just on the ears, so no fault of the adhesive or the lights. Again the lights were not damaged.
