What are the differences in the 3x21 series for Convoy?
3x21A - medium sized smooth reflector options, either single (SBT90.2) or triple (SST40, SFT40, GT) emitter setup. No handle included. Set up as a medium range thrower. 3x21B - medium sized orange peel reflector with triple Cree emitters. No handle included. Set up as a high output medium range flooder. 3x21C - small orange peel reflector with 7 emitters (SST40 or SFT40). Handle included. Not entirely sure what the use case for this one is. I would expect a pretty floody beam pattern. 3x21D - large smooth reflector with SBT90.2 emitter. Handle included. This is a long range thrower. 3x21E - small TIR optics with 12 519A emitters. Handle included. Basically just 3 D4Ks taped together. Use case varies depending on the angle of the optics. I'd say most people would want something like this set up for short range flood of high CRI light with the 30 or 60 degree beaded optic. My personal recommendations would be the 3x21B for the use case you described in the other comment. More on reddit.com

What a 3x21
Most good throwers are not multi-emitters. Typically they involve one single, high candela emitter in a large reflector or optic. Think the 3X21D and the L7 if you're going with a Convoy comparison. Other long range LED throwers include the Acebeam K75, the Amutorch DM90, the Astrolux MF05 or Mateminco MT90 PLus and the Lumintop GT110... The only other extreme range thrower that is multi-emitter is the Wuben A1. But you'll have to pay USD$700+ for it, even on sale. Past discontinued multi-emitter throwers like the Lumintop GT94X or GT98 are rare now to find. More on reddit.com

When Harold said "Kill them all" if they harmed Grace. Gave me goosebumps.

Nice to know that even Harold can't stick to his ideology in every circumstance.

November 21, 2024 - Even though the 3x21c has the same emitter options as the 3x21a, it'll be floodier since the optics are more shallow than the 3x21a. So it'll be a more concentrated flooder vs the 3x21b, which will be more floodly with its 7070 emiters (vs 5050 in 3x21c).

3 X 21 Inch Silicon Carbide Sanding Belts, 8 Pack
Our 3x21 industrial grade silicon carbide belts are the perfect choice for fine finishing with lighter pressure. Silicon carbide is extremely sharp and friable, making it ideal for heat sensitive applications but not as long lasting as other abrasive materials. Its unique characteristics make silicon carbide a great choice for paint removal, sanding between coats, knife scale finishing, lapidary, or any application requiring consistent scratch patterns. Wet or dry applications. Hand built in the USA. Available Grits: 24, 36, 60, 80, 100, 120, 150, 180, 220, 320, 400, 600, 800, 1000  Single Gri

r/flashlight on Reddit: Convoy 3x21 series differences
April 3, 2024 -

Hello,

I recently bought an L21B from convoy, which appears to be a fantastic thrower from my 4 camping trips of use. I was hoping someone could explain the differences between the 3x21 series. They come in A, B, C, D, and E versions. Or if there is a resource that explain the difference that I’m missing please let me know. Sorry to waste your time if there’s an explanation page I’m missing I swear I tried to find the difference for a half hour today. https://convoylight.com/collections/3x21
