At the heart of the Fenix LD36R flashlight are three second-generation, top-of-the-line Luminus SFT-25R LEDs, which generate a light beam of up to 3600 lumens with a beam distance of up to 385 meters, and an additional three RGB LEDs, which are your ticket to the fascinating world of colorful illumination. This elegant and multi-purpose flashlight is not just about power, but also about versatility, making it a reliable partner for any adventure, from demanding mountain ascents to creative photography. What truly sets the LD36R apart is its colored light. In addition to standard white light modes, it also offers full-featured RGB lighting with stepless selection of any hue. Create the perfect atmosphere while camping, spice up your photos, or use the colored light for signaling. There are no limits to creativity. The package includes a Li-ion battery with a capacity of 6000 mAh, which provides the flashlight with power for more than 65 hours of operation. Recharging is a breeze thanks to the modern and waterproof USB-C port directly on the flashlight's body. Thanks to the standard 1/4' thread on the tail, you can mount the flashlight on a tripod and illuminate your entire workspace or campsite without having to hold it. With the included diffuser, you can also transform it into a perfect reading lamp or an atmospheric light with diffused colored light in the blink of an eye. The LD36R is the perfect choice for anyone looking for more than just an ordinary flashlight. It will be appreciated by demanding hikers, climbers, campers, and photographers who want to experiment with creative scene lighting. It combines uncompromising performance, multifunctionality, and durability in one elegant body.

All flashlight parameters (luminous flux, battery life, waterproofness, beam distance, and impact resistance) are measured in accordance with the ANSI/NEMA FL 1-2009 standard.

Using the Fenix LD36R Flashlight

From the factory, there may be an insulating cap on the battery inside the flashlight. Remove it from the battery before first use.

Turning on/off and switching between power and color modes - To turn the light on or off, press and hold the side button for about 0.5 seconds if the lighting mode is selected (W for white light or C for colored light). If the rotary switch is in the central locked position, turn on the flashlight by rotating it to the symbol of the desired lighting mode (W or C). You can switch between white light (W) power modes at any time during operation with short presses of the button. Press and hold the button for 1.2 seconds to activate the strobe, which you can turn off with another press of the button to return to the previous white light mode. In color lighting mode (C), you can cycle through the colors with short presses of the button: red - orange - pink - blue - purple - green. Long-press the button to activate stepless color change - release the button when you reach the desired hue. A subsequent short press will switch you back to the originally selected color from the 6 predefined ones.

Memory for the last set mode - The flashlight always turns on in the last selected mode, with the exception of Strobe and stepless color change.

Lock/Unlock - To prevent accidental activation of the flashlight, e.g., in luggage, quickly double-press the button (the flashlight must be off); the flashlight will then blink and be locked. To unlock, quickly double-press the button again. You can also lock the flashlight with the rotary switch by moving it to the central position. Both locks can be combined, locking the flashlight first with the button and then with the rotary switch. Accidental activation can also be prevented by loosening the flashlight head.

Battery Replacement - Unscrew the head of the flashlight and insert the battery with the positive pole facing the head. Then, fully tighten the flashlight head again.

Charging - Open the anti-dust cover and plug the USB-C charging cable into the flashlight's charging port. After charging is complete, seal the anti-dust cover again. The typical charging time for the included ARB-L21-6000 battery is 3.5 hours with a 5V/2.5A USB source. During charging, the indicator glows red. Once the battery is fully charged, the green indicator will light up. The flashlight can be used in any mode except Strobe and stepless color change while charging, but depending on the battery's charge level, not all modes may be available, and the total charging time will be extended. 

Battery Level Indication - When the flashlight is off, a short press of the button activates the battery level indication for three seconds. Green indicates a sufficient charge level (100% - 85%), flashing green (85% - 50%), solid red (50% - 25%), and flashing red indicates a critically low battery (25% - 1%). If the battery is low, the flashlight will gradually and automatically switch to lower power modes. In the lowest mode, the battery level indicator will flash red to warn you to recharge or replace the battery. This function only works with original batteries.

Intelligent Overheat Protection - When using the flashlight in high power modes for extended periods, a large amount of heat is generated. When the flashlight reaches a temperature of 60°C or higher, it will automatically reduce the output by a few lumens to lower the temperature. When the temperature drops below 60°C, the output will gradually increase again.

Low-Voltage Warning - If the battery voltage drops below 3.0V, the flashlight will automatically switch to a lower mode until it reaches the lowest power mode. After reaching the lowest output, the battery status icon on the OLED display will start flashing. In this case, recharge the flashlight as soon as possible or replace the battery with a charged one. 

Warning

• Do not disassemble the sealed parts in the flashlight head yourself, as this will void the warranty.
• Use only the high-current rechargeable 21700 Li-ion batteries mentioned above.
• If the protective rubber O-rings appear damaged after a long period of use, replace them. The rings should also be lubricated to prevent rubber erosion. By following these rules, the flashlight will be properly protected against water.
• If the flashlight does not switch to higher power modes, flickers, or does not turn on, it may be for one of the following reasons:
  • The battery is almost empty - recharge it.
  • The contacts inside the flashlight are dirty – clean them with a cotton swab dipped in alcohol.
  • The tail cap of the flashlight is loose – tighten it.

Warranty

Five-year warranty on the flashlight, two-year warranty on the battery.
