1 Year later updateThis light does a good job. Purchased 2, then 2 more and now 1 year later 1 more. Giving this a 4 star NOT due to the product but to the installation instructions and hardware NOT included to properly mount this light. The light output is enough for total dark area to be well lit (see Lumen info below & picture). The metal bracket attached to the solar panel is flimsy (low grade metal) and would not support the weight of the unit without other methods used to secure panel. There is a general lack of screws and washers to properly install panel or light. You will need to supply your own.1 year ago, a message was sent to manufacturer to update their installation instructions. They did put a “contact” method on the sheet now. Other than that, the directions are fairy poor. They do disagree with that assessment per their response a year ago. (See picture of paper insert).Installation is not really that hard. My installation is on a wood pole. Regardless of how power panel is mounted, flat surface like wall or roof the installation would still be problematic. I had to drill holes in the metal power frame where I wanted to attach a screw. Using ONLY the metal bracket provided, the weight of the power panel will not hold the panel in position securely without some other attachment method. A flat surface mount still would require some hole to insert a screw. The bracket is just not strong enough by itself. The bracket attached to the flood light is somewhat stronger.First, the ad is mis-leading. Maybe this light can output 24,000 Lumen. At factory default settings, output is about 4,000 lumen (see picture). I did question the manufacturer about this issue and got a vague answer. Overall the light output is enough in a total dark area to light up objects 50 or more feet away. So far, over for the last year, the light has had enough power to last all night without draining the battery. There are 4 of these across 200 foot (2 on each side pointed towards each other) and light output range is almost enough to cover that area from total dark to enough to identify objects and really see objects closer to the light pole.******* 2021 review below ****Installation was fairly simple. Instructions are inadequate. To basic without good illustrations or descriptions. Included hardware is a little more complete but will need your own washers and screws. The U-Frame for both parts is flimsy - will not hold the weight of the unit good without bending. Our install put the solar panel bracket on the other side of the wood pole so the weight was offset allowing the panel itself to reset on the pole. A flat surface like a roof would also work.Pictures are lights on opposite sides of barn at complete dark - LED lights are what is making it look lighter. No other lighting around. Output of light is impressive. this area is a totally dark field at night. This brand seems to handle the 12 hour time limit and good coverage area of light. We purchased 2 and then 2 more. Worth the money.Install instructions (1 page) says call them if problems but no where will you find a way to contact them.Overall, pleased the the light output at factory settings. In a dark field in rural area with no other lighting, it does a good job.
