Best Praise
+54 pts“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)”

+41 pts“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.”

Best Praise
+30 pts“\> If you use a thrower, you’re still only lighting up the ground, but you can light it up waaaaay over there 👉 That's a good point. It's useful but also super fun in huge fields! I recently went to the park and my L21B LHP73B lit up quite a distance.”

+12 pts“Next time, please put a note in requesting that Simon fixes the L21B reflector/gasket issues with the smaller emitters. He's been ignoring me & many other's for over 2 years now.”
