Lamp is not protected against rolling.
Light distribution "Broad Beam Lens": small bright spot with weaker-lit environment. Bright spot about twice as large as in LD12. Compared with E05, E12 has a smaller but usable light area. The "width" beam does not fall out as wide as it is possible with other Fenix lamps. Inconvenient if you want to illuminate a dirt road in its full width. Deficiency in Fenix and many other flashlight providers: they make no useful information on light distribution.
Better compared to E05 is the level windscreen.
