So I continue to do "Abuse' testing to have an understanding of what these lights will take. So after the drop tests and such, I sprayed the light with a garden hose from different directions. I also dropped it into my portable hot tub for a one hour soak. Took it out and it is completely dry inside. I played with the switch like a nervous person on too much stimulants today doing while doing tasks. I continually dropped it today from about waist height. I then dropped it back into the hot tub for about a 3 hour soak. No water intrusion. I am going to continue this abuse testing until I have something to report. This is giving me a high degree of confidence in gifting these out. Thanks for the recommendation to this product.
