Just an FYI for people in the market for hunting and/or camping items. Always check the clearance aisle in your local Tractor Supply Store. This week I picked up a Treeline (store brand) Mossy Oak 600 lumen USB rechargeable headlamp. It was marked down from $39.99 to $17. The nice feature is that there are 2 on off switches. One for the 70 lumen green or the 50 lumen red led and another switch that cycles the 2 white led settings of 600 and 300 lumens. Other headlamps sometimes require that you cycle through white, red and green before you can turn them off. I also like the fact that I can charge this in my car or in the field with my portable USB backup battery that I carry in my pack. I have a 320 lumen AAA headlamp and this one from Treeline literally outshines it by a mile. Well, by 100 yards at least. lol The run time is supposed to be 3-4 hours on high (600 lumens) and 4-5 hours on low (300 lumens). Charging takes 3-4 hours, so I'm going to keep it in my pack as my primary light and use the AAA headlamp as my backup. Remember one is none and two is one.
