I purchased Both a H31 and a H31fw and am really happy with them both. The floody with the neutral is great as a head lamp and the H31 white has found its way into my pocket as a backup EDC. After a few nights with these lights I boxed up my newly purchased Surefire minimus and sent it back. It was like having a brick strapped to my head after using the H31fw.
I was out in the wood just last night with the H31Fw and used the higher of the lowest settings most of the time. Plenty of illumination from this and the color is great. I also carry a Nitecore EC 25 as my thrower.
These lights are really minuscule. The large LED and some what small reflector make for pretty good coverage.
As you have probably guessed by now I recommend the H31fw as the headlamp of choice for camping.
