See post 7 above. The Mawri mounts are fairly cheap, rugged, strong and easy to remove. They actually have 2 parts so that the clamp stays on the bike and the light is mounted to a sliding mechanism. Here's the Expilion on the Mawri mount
And the mount without a light
I just leave them in place all the time.
Back in the days of flashlights, I use the same clamp
For "Magicshine" lights, there is a cheap plastic block that screws to the bottom of the light.
Hoffman even has a good mount for a helmet
I have managed to break a couple of mounts but that was only because of a spectacular crash I had. I'm reasonable certain that no other light mount would fair better. That particular mount has been kicking around since 2008 so I'm reasonably certain about it's durability.
