According to you in everything, just like you, I doubt that the MF02 deliver the advertised specifications, i think will be closer to 1300-1400 meters, but likewise, I am eager to have it.
throw is a ratio on diameter squared, so 89.9 sqr/71.4 sqr = 1.58, so assuming the TN42 throws 720 kcd (it's higher than rated 600 kcd), so the MF02 should throw 456 kcd at the same amps/output, but since it's 35% higher, then the calculated kcd should be: 456+160 = 616 kcd. There's not many reviews around on the TN42 I could find but JM's review has it at 1,965 lumens, 728 kcd, ballpark 2,000 lumens and 720 kcd
So if the LED and optics are the same, the MF02 should throw 616 kcd if I did the math correctly. I've been under the impression the TN42 has pretty darn good LED and optics as well.
Of course it is not a BLF designed light. But “Freeme” managed to make some changes in the Astrolux MF01, and one of them was to add one more mode. For that reason I ask the question, maybe he can do the same in this case.
I just found out the regular price of the BLF-Lumintop GT is going to be $259 and the group buy price is probably going to be closer to $159. It helps to put into perspective how inexpensive the MF02 is.
