First, the product is great as it does what it says it does provide a light on a post. It works great and for me the battery lasts the whole night. I have no problems with the product as is except that when I ordered many. Some came with different color screws some fit and others didn't the company mailed me replacements at no cost. The issue isn't with the product or manufacturer but rather with Wayfair as they falsified the product and its capabilities. A, it is a single light so it does not accommodate 3 lights as the description states. B, the bulb is not replaceable as stated in the features/description. So, in a nutshell, if you those items aren't on your priority list, this is a perfect light. I installed 8 of them in an area of 12x25 L layout and Z layout and are  less than 6 feet apart.
