tldr; Budget thrower with SFT40 or LHP73B. Incredible value for distance. Heats up fast but pocketable.

Best praise vs top criticism for Convoy M21B
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.”

What Redditors Say
Best praise vs top criticism for Convoy S21E
Best Praise
+18 pts“If you're going into this and these are your first Convoy lights, then you really have a core grouping that I think you must go for: 1. S6/S8, with 3000K 95CRI SFT40, 8A buck driver 2. M21H, with the XHP70.3HI 4000K R70, and select every possible TIR to swap in so you can try them all 3. S21E, with the 3500K B35AM, and like the M21H, select every possible TIR to swap in These 3 should get you to about $100 roughly, and it's a good start for general use and in the case of the S6/S8, slightly floody-throwy options. All of them should sport a boost or buck driver for great runtimes, low heat and decent efficiency and sustained output.”

+15 pts“That sucks! I let some carpenters borrow an S21E once when they were working on my carport. Well they left before I knew it and the guy I let borrow the light never came back on the next couple days before they were finished. I asked the other guys that came back the next day and they acted like they had no idea what I was talking about.”
