I dont know who it is or what cells he is using, 50s seems a little quick! I would guess at 2-3m but bare in mind its near 13k lumens in a coke can..............The tn36 lights are quite impressive for size/heat tbh. Its a mode for short blast either way, any light at that output is going to get warm-hot quick. Yet the lower modes(say lower but still crazy outputs) will run longer than the standard light due to the extra heat sinking.
If you want long run times and high output, you need to go big!tk75vnQ70 with 4x xhp70's and 15k lm, rc40vnT 8000lm and 500kcd

The medium and high modes are where you will get run times and more than enough output!
I love both them big lights, I actually want a big light, but just the price that scares me with these vinh lights.
