Fenix ARB-L18-3400U 18650 rechargeable Li-ion battery is recommended for maintaining perfect lighting performance. Warning: Do not mix batteries of different brands, sizes, capacities or types. Doing so may cause damage to the flashlight or the batteries being used. *18650 /16340 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Only use quality batteries with circuit protection will reduce the potential for combustion or explosion; but cell damage or short circuiting are potential risks the user assumes.


Battery Replacement

Unscrew the light body and insert the battery with the anode side (+) towards the light head, then screw the light body back on.


LD30 Low-voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. When this happens in Eco output mode, the battery level indicator blinks red to remind you to recharge the battery. To ensure normal use, the flashlight will not turn off automatically and will work till the battery level runs out. Note: This only works with Fenix 18650 Li-ion battery.


Intelligent Downshift

Time-limited Downshift After 5 minutes of maintenance, the brightness of the flashlight decreases by about 30 lumens every 6 seconds, and until to about 1200 lumens. 


Overheat Protection 

  1. With the light switched on High output level, and the temperature is detected ≥55°C. The brightness of the flashlight decreases by about 30 lumens every 6 seconds, and until to about 400 lumens. If the temperature is detected <55°C, the brightness of the flashlight increases by about 30 lumens every 6 seconds, and until to about 800 lumens. After the brightness downshifting, High output can be reselected.
  2. With the light switched on Turbo output level, and the temperature is detected ≥55°C. The brightness of the flashlight decreases by about 30 lumens every 6 seconds, and until to about 400 lumens. If the temperature is detected <55°C, the brightness of the flashlight increases by about 30 lumens every 6 seconds, and until to about 1200 lumens. If the temperature exceeds 55°C in the first 5 minutes, the brightness will drop directly to 800 lumens. After the brightness downshifting, Turbo output can be reselected.

Voltage Downshift

When the voltage level drops below 3V, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. (After the downshifting, other output levels can be selected by single clicking the side switch, but if the battery voltage is still detected below 3V, the downshifting will begin after 1 second).


Usage and Maintenance of the Fenix LD30

  • Disassembling the sealed head can cause damage to the light and will void the warranty.
  • Fenix recommends using an excellent quality battery.
  • If the light will not be used for an extended period, remove the battery, or the light could be damaged by electrolyte leakage or battery explosion.
  • Unscrew the tail cap half a turn or take out the battery to prevent accidental activation during storage or transportation. Recharge a stored battery every four months to maintain optimal battery performance.
  • 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 lamp's performance as dirty contacts may cause the lamp to flicker, shine intermittently, or even fail to illuminate for the following reasons: 
    A: The battery needs replacing. 
    Solution: Replace battery (ensure battery is inserted according to the manufacturer’s specifications). 
    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 contact your authorized distributor.

Good stuff !

It is a good light compact, good for edc would recommend for someone who carries a light all the time it rests in the pocket well I occasionally have a issue with accidental tail switch engagement, but a very small critique for what I consider a good light to have on yourself always

Excellent EDC, with an often-overlooked benefit: a great beam profile

I own several Fenix Lights, and all of them have performed well. They're solidly built, and reliable. I've had the PD35 for several years, but switched to the LD30 once a friend showed it to me. It's just slightly smaller....but that small difference makes it a lot easier to carry in a coat pocket.

More importantly, it has a slightly broader and more useable beam profile than the PD35 and PD36 (which were my other go-to Fenix lights). The hotspot is a little wider, and there's less of a distinction between the hotspot and the corona, This makes it a lot easier to use for short- to medium-range tasks. It still lights things up far away - and I live in Alaska, so I need throw! - but for most of my uses, which are 5-50 feet away, the beam profile is softer and more useable.

Everything else - body style and grip, reliable rear clicky, and battery life - are great. I'd love to see a slightly lower "low" option - maybe a true moonlight, or something that's 5 lumens or less - but you can't have everything in a light. The levels are well spaced, and very useable. If the LD30 came with a slightly warmer / neutral LED, it would be nearly perfect!

It's a great flashlight, and an excellent EDC. Buy it; you won't be disappointed.

I own a couple of E15 and wanted another light to have in my car. The LD 30 fits the bill perfectly.

Great EDC light

This light (like my other 3 Fenix lights) is well built, I purchased this LD-30 to replace the stream light I carry on my belt. It gets used daily in my work and so far is performing well. The amount of light it’s capable of is staggering! I typically use this light on the lower settings. I bought this model because it uses the same rechargeable battery that my othe Fenix lights use. The only problem I have had so far is finding the light on while in the holster. Apparently the tail switch can be activated inside the holster. The holster is another pet peeve, it’s a cheap after thought. At this price point, a durable leather holster with snaps should be standard. Apparently Fenix disagrees. I love the clip provided with this light, it can be handily affixed to the bill of my ever present ball cap for hands free lighting. I also like the idea of the diffuser accessory available, hang the light up in a tent for good area lighting. I have not as yet got to try one, but it’s on my bucket list.


The power of luminosity in the palm of your hand! What’s that? Your hands are full? No problem - the LD30 is easy to chuck in a pocket for later illumination! What a fantastic EDC light. It’s also really well suited for ultra-light backpacking or any other outdoor activity given it’s robust build, great beam spread and long lasting run time.
