Thank you all for the answers, now I have 3 lamps, MN60 at 225 lumen, the MN61 at 350 lumens and the MN 62 at 500 lumen probably with a run time of 7 minutes and not constant at that.
(I could be wrong with the figures, so anybody who knows different, please correct me)
I will probably will go with the MN61 at 350 lumens, but I need the output of peopple with experience, what about overheat in the thin E Balrog body??
Anybody knows how much run time I can get out of the 4 batteries and the MN61??
Will this conversion be feasible and comparable to the M-4??
Thank you guys!!
