He has one almighty TN31 and he also has a TN30 that is dedomed and a few other lights. I highly recommend Vinh’s work. I have his de-domed TN31 and K40 and nothing in my arsenal will touch them for throw.
Well, tonight for me it will be the battle of the throwers... Vinh's K40 against his TN31, and the FF4. Of course the FF4 will smoke both in power, but I'm very very curious to see if I can see a difference in throw. Based on numbers others have posted the TN31 should beat even the FF4 in throw, and even the K40 is just incredible.
We're slowly but surely approaching the holy grail of flashlights.... at least to me, of being able to light something up literally a mile away for under $200.
The TN31 de-domed XM-L2 will beat the FF4 in throw. You may not be able to see it much. But with good focus pictures on manual exposures with fast shutter speed and ISO turned down and white balance off or set to fine or the image of the sun on a good camera you will clearly see the Vinh TN31 clearly wins at 500K vs 430K.
I have a feeling after getting my first TK75 modded by him, I'm gonna need him to do the second one too... getting the first one back hopefully monday. In other unrelated news... he is freaking FAST in doing these mods.
