I think a genuine Atomic Beam (branded) flashlight should be part of every serious flashlight collection.
I sometimes enjoy breaking mine out and doing a zoomie beamshot, then following that up with something like an Emisar D4, and ROFL.
As virtually every non-flashlight savvy person knows of the Atomic Beam brand and probably(?) thinks they’re the bestest most powerful flashlight in the world, the comic relief one can derive from seeing the expression on their faces after being exposed to something truly impressive in a side-by-side comparison can be priceless.
