Brocken,
I never would have though that a light could be bright enough for me either. Then - I got an M6 ......
I hardly use the MN21 500 Lu LA for 20 minute option, except to help out with the security of my apartment block: to shock people hanging around for dodgy purposes.
The MN20, with 250 Lu for 60 minutes is a really practical and luxurious brightness, with a superb beam pattern. The pure quality of the light is an extra which makes it double the value (to me).
For all practical purposes, I've found *The Answer*. (!?!?!!)
I've had it a few months now, and still feel the same, so it's not just the novelty value of such a small powerful package.
And it's the LOLA I prefer, not the HOLA - weird ......
