The only one I can think of is the Surefire Beast 2. But anytime I find one for sale it's usually beat up and they want way too much for it. Not to mention it's not very bright or tinted well as more modern HID lights are. I would really like something like the Beast 2, but more powerful and better tint obviously. Does anyone know of anyone with plans to make such a light? I really like the utility of being able to pop in primaries when the rechargeable battery is dead.
