Ok, so my Quark AA regular (R5) is my first non-Fenix light and I love it. Great light all around. I also love my LD10 R5 but I got the Quark to replace the LD10 as my around the house light due to the moonlight mode. Anyway, my Quark is listed at 109 Lumens OTF and the LD10 at 100 (ANSI). All the reviews I've read suggest that the Quark should be a brighter light on Max, but my experience is very much to the contrary.
First observation on Quark AA is the tint is MUCH warmer than the LD10. It's a nice change from the Fenix cooler tints. Next is that the Quark is much floodier than LD10...this is nothing new. The thing that gets me is that comparing both lights on Max/turbo, the LD10 seems much much brighter. The reflector on the LD10 is smooth and seems more suited for throw, vs orange peel on Quark. It definitely puts more light down range. The beam is much tighter. After lots of side by side testing of my Quark with the LD10 and many other Fenix lights, my (very unscientific) conclusion is that the Quark seems to be maxing out somewhere in the 80 lumen range (on Fenix/ANSI levels).
Is this an illusion caused by the warmer tint of the Quark, combined with the floodier beam? Or is the Quark actually a less-bright light than the LD10? I'd be very curious to get others' feedback/experience on this. It kind of bugs me that the Quark falls short of the Fenix on brightness. Again, I love the light, just wish it that extra oomph that my LD10 spits out.
Thoughts?
