Question: how long will the lights stay on with fresh batteries?
Document: These lights are spot on for any standard cornhole set. Very easy to install. Batteries weren't included (I dont think) so you will need to purchase a 9v battery. Other than that. Works great! :)
I had purchased a regulation cornhole set from another Amazon seller, and since we often play late into the evening I figured some lights would help. Boy did they! These are very bright and have held up to our play thus far. The instructions are straight forward and they install in minutes with just a screwdriver (faster with a drill/driver). They allow play to continue long after sunset, and that's what we wanted.
Ordered in advance for my brothers birthday and had them installed and when we put the batteries in and turned them on, one worked great and the other had two of the LED bulbs burnt out and was very dim... If they both work it is a great product though
This product is great. We play at camping all the time. We always stopped when it got dark. Not any more. this light lite up the hole we played all night long. Highly recommend great product.
Though these are a great idea, its only great if they work properly. My fiance ordered these for me with the boards ang bags, so when they arrived I was excited until I noticed one of the lights wouldnt stay on. I've made several attempts to contact the seller with only one reply, weeks after I sent a message and am still waiting tonhear back on how they wish to resolve the problem. Very poor customer service and poor quality control. I wouldn't recommend buying from here.
I made my own cornhole game and THIS light set was the highlight of it. The partygoers were able to play well into the night. The quality feels a little on a cheap side but they work perfectly and after several parties, these still work perfectly. You need two 9 volt batteries. It attaches easily with small screw that come with it and has an on/off switch.
Made Very cheap delivered with a few of the lights not working.
