Okay... so I like to ride my horse at night. I modded few headlights in past, and found that I sometimes like to use _very_ low power levels. Like 10uW (That's 0.001 lumen IIRC), because they preserve night vision, don't annoy people around me too badly. I even put a headlamp on a horse... it worked, but then I realized that it may not be so good idea. Now... my girlfried gave me Petzl Nao (big thanks to her). It is beatiful, feedback-control is actually very nice. But... it does not really have low power modes, and does not fit under helmet. My horse says I need to wear a helmet (6yr old fjord). I tried setting it up on the computer (and control software is slow with bad user agreements), but even lowest setting is way too high -- and that would not help with helmet issue, anyway. (And its low-battery behaviour leaves something to be desired. You have light on lowest setting to preserve power, and then got hit by three unexpected, very bright flashes. I did not like that, and nor did the horse. Ouch and when battery goes _really_ low, it still shines (good), but can't be turned off (odd)).Is there something you'd recommend? ZebraLight H502 looks quite sweet with few hundred lumens down to 0.01 lumen, at pretty reasonable weight. But beam with more light in the center might be preferable.I'm searching for something reasonably small; it definitely should not have batteries at the back of head, because helmet is there. < $100 would be nice, and when batteries run low, it is important to keep giving at least some light (say 1 lumen) for rest of night. ZebraLight H600F also looks sweet, with 700lumen max and 0.1 min... but perhaps someone has better idea?Thanks, --p
