I don't have L21B sir. But I have L21A. It has good throw. What you should know about convoy flashlights is the driver inside. For example, S21B can use the same driver as used in big flashlight like L21A. The difference is just the host or led. Same led and same driver but in different host. Something like that sir.

[@corleonemichael21]

Copy sir, Thank you...

[@craigs7181]

Excellent comparison! I want one! 😛 But I just got my M21B with CULPM1 6A a little over a week ago, and I love it! So thank you for the review of the light as it greatly helped me deciding to purchase it. I'm a little hesitant to put an 8A driver in a light this size because of the heat generated, but I imagine that the lower settings would be a bit brighter too compared to the 6A driver when set to the same setting using the same led. Do you know if this is the case, or are they basically the same visually at levels 1 thru 4? I really appreciate the photos in the beginning of the video, especially the addition of the distance map. Another great comparison! Thank you for taking the time to create these videos and sharing!

[@weerapatkiatdumrong]

For culpm1, I think 6a is enough. For sft40, I haven't tried it with 6a driver. The new m21c uses sft40 + 8a driver. That's why I use the 8a driver. 8a It gets hot really fast. Next, I will try sft40 in c8 flashlight and use 6a driver because the 8a driver can't fit in c8+ or m21a. For the brightness that each driver delivers, I think 4 modes driver gives better brightness level - level1 and 2 are quite different. But for the 12 modes driver, both 6a and 8a in 1st mode, level1 and level 2 are not much different. This is what I don't like. I hope you will enjoy my review.

To be honest sir. I haven't tried high and turbo mode more than 1 minute because I made this flashlight for tactical purpose - dealing with dog chase. But from my experience, in high mode sft40 is brighter than sst40. That means it will be hotter. In turbo, it will get hot fast - within 1 minute. I am not sure whether when it will step down.
