Hi Budda.
I received the light yesterday,put four 30Qs,two of which are original button top,and the other two,are semi button top,as they have a raised top,but not exactly protruded as usual.
I have a problem to screw the tail cap,but only when there are batteries in,while it is very easy,when there are not.
Does someone face the same problem please?
And something about the intensity.I measured it at two distances,4.8m and 6.8m and the result is identical.Only 220000cd.Batteries are those 30Qs full charged by a LiitoKala 500.
