From a different thread, but relevent to this one:

I found that having it mounted that low is fine for pavement (it really lit up those pieces of debris that my previous system just washed over), but on the trail (a multi-surface MUT), dips and rises came up sudden--i.e. for serious off-road use, if I don't know the trail, I would mount the light higher.
Disclaimer, I just started using the DynoLight today. I have never used a dyno system before or any lighting system much above ~100 lumens, so I am not a good person to give comparative data.
I started using the LightOn! taillight last week. Love it, too. I'm keeping my ol' VistaLite mounted below it ('cause I just like a red blinky on the back), but I'll tell ya, from where I sit looking back, I can't see the thing blinking--it's washed out by the LightOn! taillight. Veery happy.
