* Two switches for easy selection of programs, the lamp remembers the last state when you turn off and start again in this brightness (while must be clicked in M14 with only one switch to turn off even by several programs).
* Balanced fixed Focus: A beam of light in the center, which provides in the distance for overview and a slightly weaker subjects that will brighten the surroundings and the way ahead. In focussierbaren lamps as the M14 has usually only one of these parameters (either, one sees That First Step, but it is already dark in 30m distance - or vice versa).
* Due to the fixed focus, the LD41 is waterproof and can even be operated under water, while the M14 is only splashproof.
* The maximum brightness is 680lm (compared to 400 in the M14)
* The shape of the lamp is safe even on uneven ground and can not roll away
* A Tailstand is possible (installing the lamp on the foot, so that it lights up)
* The lens is made of scratch-resistant glass (plastic in the M14)
As benefits in the M14 I see the minimally lower price and the (taste) prettier appearance of the lamp (but puts them in the daytime in the holster and the use is it anyway dark ...).
Now, after several weeks in operation, I'm still more than happy with the lamp. She is very good in the hand, size and weight are perfectly adequate and definitely because of the power jacket pockets compatible. Of the four brightness levels I use usually the two center; the lowest is more in the house or to camp sense the highest lit equal half the forest. The special features of strobe and SOS I've only tried but not used seriously.
When batteries are getting weak, the light will start to blink periodically and then switches to lower levels, so you do not suddenly stands in the dark.
Positive is still that in the package in addition to the lamp a set of batteries, a holster, a wrist strap and a second set of seals are listed.
In combination with the eneloop batteries I've found in this lamp ideal for me rounder, which is the same as in the pouring rain in the forest absolutely robust and reliable use in the house.
