Operating Instructions Two tail cap switches include the large button (power switch) and the small button (mode switch). Press the power switch lightly to momentarily activate the flashlight. Press the power switch completely to turn on the flashlight and lock it. Another press will unlock and turn it off. With the flashlight on, A single press on the mode switch allows switching between Turbo→Low→Mid→High→brightness levels; To enter into Strobe mode, simply press and hold the mode switch for about one second. To enter into SOS mode, press and hold the mode switch for about three seconds. To return to the non-flashing mode when in Strobe or SOS mode, press the mode switch once. While in the general mode, LD41 memorizes the brightness level. When turned off and then on again, the flashlight automatically enters the general mode. Overheating protection: LD41 will accumulate a great deal of heat when working in the turbo brightness level for a long time. To avoid overheating the flashlight, LD41 will downshift from TURBO to HIGH after 25 minutes of use. If TURBO is needed for extended periods, simply reset it, recognizing heat build-up is probable. Battery Replacement Unscrew the light head to take out the battery holder. Insert the batteries correctly according to the signs at the bottom of the battery cassette. Put the battery holder into the tube with the round side of the battery holder toward the light head and the groove in the side toward the raised place in the inner wall of the tube. Screw the light head back on to test. Usage and Maintenance
  • Please don't disassemble the sealed head as doing so can cause damage to the flashlight and will void the warranty.
  • The circuit is programmed with a low-voltage protection function. If low voltage is detected, it will enter into the lower brightness level. If low voltage is detected in the Low brightness level, it will blink three times a second every 5 minutes. To allow normal use, LD41 will not turn off automatically and will continue to work until the batteries are depleted.
  • To get the most from this LD41, Fenix recommends using high-performance Ni-MH rechargeable batteries. Alkaline batteries will reduce runtimes significantly.
  • If the flashlight is not to be used for an extended period, remove the batteries as the flashlight could be damaged by electrolyte leakage or battery explosion.
  • To avoid accidental activation, remove the batteries before packing and transporting the LD41.
  • Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare.
  • Periodic cleaning of the battery contacts improves the flashlight's performance as dirty contacts may cause the LD41to flicker, shine intermittently or even fail to illuminate for the following reasons: Reason A: The batteries need replacing. Solution: Replace batteries (Please confirm the correct installation of anode and cathode). Reason B: The threads, PCB board contact or other contacts are dirty. Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.
If the above methods don't work, please refer to the warranty policy before contacting your authorized distributor. Notice: The routine cleaning video can be watched and downloaded through Fenix official website, please log onto the service channel->“maintenance for light”. Warning LD41 is a high-intensity lighting device capable of causing eye damage to the user or others, so please avoid shining the light directly into anyone’s eyes.

Have 4 of these purchased over several years time....best flashlights.


This light has multiple settings. I need it to communicate with the Strobe light from far away. It's bright when I need it the most. It's dim when I need a dim setting. I highly recommend it. A must have!

Daniel Sabedra

Great light

David Lollar

A very good flash light and well designed

Rex Hylton

Had mine since 2015 and use it exclusively for night-time boating. The half-press tail switch activation is absolutely the best. Combine that with a really good pencil beam throw and this is my go-to night light.

On paper there are better torches out there but I haven't been able to find anything to better it despite numerous purchases since.

Very happy to see that it's still in production!!
