Again, this seems to be a job for the L2D. By cranking the head to the right, the first power setting is LOW, with an impressive runtime. Yesterday I got three diffusers for my Fenix lights and they far exceeded my expectations. The light was beautiful on low.
A Fenix E01 also puts out a pleasing glow, is light and runs like the ****ens. A few years ago I bought a Brinkman Rebel 4-LED flashlight at Target. It came with two filters (red and blue) and two "D" batteries. I use it almost every night and have never replaced the orignial batteries. Most of the time, I run only two LEDs and it is fading a bit, but it still gets me around the house, even with the red filter.
So you're quite correct. Brightness is great when you need it. Fenix wisely designed their lights to give just what is needed.
