Wow! I bought one last night and used it this morning before sunrise. It was incredible. I have a cateye el-220 that I use on my road bike, and this really outshines that. I used the conduit clamp mount and it works very well so far. Its hot in the middle, but it also has a nice halo that works well for what I need. I usually ride on pitch-black bike trails and there isnt much better that I have found yet. It so happened that I passed someone else this morning and I couldnt even tell he had a light on until I looked at him. There was that much difference. Big thanks to the OP.
