I recently bought to Quark lights for use at work (Infantry) as well as for EDC and allround use. The models I bought were the Tactical QTL and QT2L. Both run 205 - 230 lumens max output. My experience with handhelds is limited and my first thought was going with max and moonlight as my two modes. At max the lights easily light up a 50 yard long dark hallway good enough for PID. Other work required of the light is reading maps/instructions for which I intended to use moonlight mode. But is 200+ lumens overkill on a handheld light? Is it better to go down in power and increase battery life? Maybe the 85 lumens setting would be better fornallround use? Obviously it is very hard to give a set of rules for these types of questions but I'm interested in your thoughts (I'm sure there are some people with similar use for their lights and lots of experience) to help get some perspective on this.
