Here in Utah, we cannot use a light that is plugged into, or attached in any way to a vehicle. I have been searching for months to find a handheld light with enough power to last for more than one stand. The best thing I have come up with is a Lightforce handheld with multiple portable battery packs. Still, I'd have to have back-up batteries charging on the car-charger and several other power packs pre-charged just to get in a few stands during a night hunt. I need a light that can last through a full 20 minute stand without having to shut it off and still be bright enough to shoot by after 20 minutes of continuous running. It looks like the days of all-night hunts are over here in Utah, but I'd like to be able to get in 5 or more stands in a night. Any ideas?
