“Hard to know without knowing what it has to beat, but for a budget light that will go very bright for short bursts the Convoy m21b with lhp73b and a jp40 battery. Will also need a separate charger (can get from the same website)”

“Literally me. When I got out of jail after being arrested I realized both my M21B LHP73B and X4Q Comet were missing, and I'm almost certain the cops stole them from my car because they suspiciously won't release the bodycam to my attorney.”
