What Redditors Say
Best praise vs top criticism for Convoy M21H
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.”

+8 pts“Thanks! I hope you upvote, I tried to find m21h vs if22a comparisons but literally found none, so I'm wishing more people see this and throw lovers like me don't regret getting the m21h and be disappointed, m21h would've been peak flashlight for me if it had 150k candela and maybe 5000 lumens, but I get that there are MUCH more expensive flashlights out there for that purpose such as FFL E90 Blaze or DM11 i guess...”
