I have them both and they are two very different lights. the FF3 puts out more light in a nice wide pattern and it throws quite well with a very pleasing color beam. Somewhat like a TK70 but more light output and warmer.
the mod TN31 is a bit bigger has the variable outputs and throws a narrower brighter beam further. How much further I'll leave that up to the experts but my estimate is maybe 20 to 30%
Maybe someone can post some side by side photos I dont have any
Walterr839 you're a legend that's exactly what I wanted to know 🙂.
I am kinda surprised no one has compared them already as they are about same size and price and two very powerful units apparently!
It's throw that I'm after not spill and if led with longer run time will out-throw the hid then I'm sold.
i second the beam shots, if anyone has some that would be great!
Thanks again
