Got it last year, have used it 5 or 6 times. For what is actually a "home made" light kit, the quality seems great, extra battery pack is cheap. I did a little over two hours Tuesday, expect it will go 3 hours as he stated.
Beam is as good as my Topek HID, but unlike a HID it is instant on or instant off.
Unlike an HID it is cheap to repair if it breaks
I see no need for anything other than on/off. I suspect people use a low beam so teh battery last longer, the low beam on my HID is not much different than the high setting.
Went with the flood after two rides with the spot, I saw no need to see 100 plus yards out, need wide view for 25 to 50 yards for Florida trails, Out West the spot would be a better helmet light.
One of my fellow riders has a Stella 180, the Amoeba kills that light.
Come out to the TNR, see it up close. Ask Sandpine how it looks
I'll have it at the FTF Sat too.
