I'm in the market for a new light and this sure looks interesting. I have the LightForce 170 hunter setup and it works, but is really large and I can only get around 30-45 minutes runtime up here at -40. It's an absolute nightmare trying to carry it, the battery pack, rifle, caller, and other gear with an insulated snowsuit on. So, I have a few questions that hopefully somebody can answer, or maybe I missed them above and somebody can re-answer for me. I can't see the photos until I get home, so if there's a detail in the photos that answers my questions, I apologize. Can this battery be charged from a 12volt cigarette lighter? That's a very important feature for me because I charge batteries from my snowmachine on multi day trips. If I can't charge from a 12 volt cigarette lighter, how easy is it to change out the batteries? What is the housing made from (Lexan)? What are the overall dimensions of this light? If you're thinking about a pressure switch as bgtme mentioned, is there a way to get a high silicone wire, so I don't crack it at -40? Or if possible, will you sell just the jacks and switch so I can use my own arctic wire? Do you need a true arctic weather test on this light at temperatures below -40? If so, PM me and let me know. I think the LED setup is a great idea, especially for the battery and bulb life.
Edit: I see there is a car charger for this light. Is it a straight cord/plug to the battery, or is there a mid-section "box" that would require cold weather protection or mounting?
