Although I didn't treat my Borealis like blackbear84 did on his website, I can personally tell you that it can handle anything.

I accidentally dropped my Borealis head first on concrete. The drop was about 3 feet. I was scared that I cracked the lens or somehow damaged the bulb, but the Borealis was fine!

I want to say that I had his optional new crenellated bezel equipped. That thing dug into the concrete. I wish I had taken photos, but I can guarantee you that it happened! Even though they are now made of aluminum instead of stainless steel, it is just as strong and its MUCH lighter. It is not as head-heavy. I love it!
