Will get past the best, as no such thing, completely subjective........just like which is the best colour.
So , acebeam k60,
Thrower wise acebeam k70, olight sr52UT and several others are all great lights out of the box.
Fenix tk75 is a great light out of the box and so is the rc40 for the run time on max
Flood lights, the niwalker mm15 variations are great, as is the mm18 , thrunite tn36,tn36UT
T6 is great out of the box
Will take one example, lets say the jetbeam T6
Specs
Maximum output: 4350lumens
Max beam distance: 750meters
Lets take a modded one
T6vn
Lumen: 6300/5800
Lux: 430K/400K
Max Throw: 1300m Throw
So gained 2000lm which is best part of 50% output, and as good as doubled the throw from 750m to 1300m
So why go out of the box
With all the threads going on, lots are crossing and all similar, modded or not etc
My advice is get a vinh light around what use you require, you wont regret it and nothing will change that recommendation........Believe or not, i am actually saving you money!. You will buy a standard light, after a few days you will then wonder if you had got a modded done............it would happen trust me!
My advice is based on my experiences and trying to help other miss out a lot of the middle ground and just get straight to the better performing light/s.
