For the cheapos like me, here is an alternative..

Here is the Two Fish mount, off Amazon for $7 to $8, maybe shipping too.



Here are the Two Fish COPIES/KNOCK OFFS, I have been using for $2.25 each..Discounted when you order more than one. I just re-ordered 5 for $10.53 with free shipping.



They work perfectly.. even rigged one up to my helmet..


Here is one I mounted on my beater bike. That is a fat 26650 flashlight too. Much thicker in dia that most flashlights. The two fish copy handled it easily..
