Review on Birdi Disc Golf - Flat Circular LED Lights for Night Disc Golf - 8 Pack (Multi) by Scott Rao

I play a lot of disc golf in the evenings. These lamps are the worst I have ever used. I'll start with the positive things. The 3M adhesive is great, once the light is attached it doesn't come loose. That's where the positives end. The light turns off at the slightest impact, be it a tree or just hitting the ground. The switch stopped working after three or four uses, whether it's impact damage or just a defective switch I don't know. The lights also burn out after just six hours of use. I would suggest buying a different lamp instead. The adhesive function alone is not worth the money.
