Review #2
I rode to work with the light at full power this morning. It's definitely different than my HID. The hot spot is notably absent. There's just all this light in front of me. The housing didn't get more than warm on the way in, and it was 6C out with a little wind. I might throw on some heatsinks if it gets much warmer. I noticed that oncoming cars stayed on their side of the street more than usual. The hacked up mounting device is working very well. If I need to adjust the angle of the light, I just give use a firm hand and it points where I want it to go. I haven't used a handlebar-mounted light for a while, so I'm not sure where to aim it.

I picked up a new seat bag at MEC, and it does a good job of holding the battery steady. The battery is a 4800 mAh 14.8V Li-ion from Batteryspace.com, left over from my HID setup. If I want to run the light at 1A, I should probably bump up the battery to a higher voltage. I have no idea what to expect for runtime. I'm assuming it uses less juice than my HID, but I could be wrong. Does anyone have a formula to figure that out?
