Glad that works for you. According to the Swhs review I linked to two of my posts up, there was a batch that had faulty electronics causing sort runtime. You might have one of those units. I'm not sure if mine, purchased late Nov 2011, exhibits this, since I didn't check runtime much before putting in the voltage converter.
I haven't looked up the marketing material, but if the bold portion is verbatim, it seems rather sketchy at best, and downright dishonest at worst, unless qualified in the literature. Certainly avoiding the "bright spot, hit or miss on curves" is a good thing.

I'll call consumer care tomorrow and find out if that run time is a problem, thanks for the tip.
The tail light I haven't seen any comparisons yet, but supposedly it mimics a car tail light, not extremely bright in the spot but can be seen from a long ways similar to a car tail light. And they built the thing with a center section being a reflector designed to work if the bats die. It seems promising, and if it's anything like their head light then it should be good, but I'll wait for a comparison.
