The Fenix LD41 is a powerful and versatile LED torch which runs on 4 (either rechargeable or non-rechargeable) penlite (AA) batteries. It is not a simple 'every day carry' torch but more a sturdy piece of outdoor equipment for serious use.
As with all Fenix products, this torch is also digitally regulated, which guarantees that the light output remains strong until the last moment even when the batteries run out.
The torch is really easy to operate. You can simply switch it on by pressing the click switch and then you can select any of the 3 dimmer modes or the highest output mode by pressing the small button. You can activate the strobe mode by switching the torch on and then keep pressing the small button for one second. Press the small button for three seconds to enter the SOS mode.

The advantage of having the ANSI / NEMA FL 1-2009 standard is that the values can easily be compared with one another and give a true reflection of daily practice.
