I took a 23 mile ride last night using the Bikeray III headlight and I am pleased to report that the BR III worked well. The light disperses fairly quickly, but it is bright enough to light the road so that I didn't out ride my light even at 25 mile per hour. I tried it as a handlebar mount and it stayed aimed where I wanted it. The low beam is only useful for very slow riding aimed at the front of the bike, so don't expect much from that setting, but I found little use for the low beam anyway. The flash is a full brightness and will get folks attention! The power indicator light is intergral with the power button and is bright, but I did not find it to be distracting in any way. The battery pack fastened to the handlebar stem securely with the provided velcro strap. The whole unit is easily removed to put on another bike if I want. I'll report on the durability of the unit as I continue to use it.

Be sure to keep it dry / out of the rain. The BR3/4 back panel is not waterproof, and rain water can seep in around the button and edges of rear panel, rendering it inoperative.

Thank you, seeker333!! I guess that is one concession for paying less for the light than those of equivalent brightness. It seems to handle shock well. I rode on a community bike trail yesterday that alternates from paved to dirt and it wasn't affected.

So far, 93 miles on every kind of surface imaginable and it has performed great. Alternating between flashing and bright beam, I have not depleted the battery. So far, I am very pleased.
