Is it normal for the Fenix LD10 and LD20 (both R4) to appear to be the exact same brightness in all modes including turbo? In other words, is the 73 lumen difference too small for the eye to perceive? I have both of these lights running on freshly charged Eneloops, and if I shine them at a wall 10 feet away, I wouldn't be able to tell which was which based on the beam. The beams literally look exactly the same.
If it helps, the LD10 is drawing 2.76 watts on turbo (2.3A @ 1.2V) and the LD20 is drawing 3 watts (1.25A @ 2.4V). I see three possibilities: (a) both lights are putting out rated lumens, but the eye can't tell the difference, (b) the LD10 is able to pull enough power from the Eneloop to put out more than 132 lumens, or (c) the LD20 is defective and is putting out less than 205 lumens. Only (c) would be a problem for me.
Anyone with both of these lights who can share their own experiences?
