ON/OFF for LD02 V2.0 CW Penlight

Fully press the tail switch to turn on/off the light.

Output Selection

With the light switched on, tap the tail switch to cycle through Eco→Low→Med→High.

Battery Replacement

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

Intelligent Memory Circuit

The light memorizes the last selected brightness level. When turned on again the previously used brightness level will be recalled.

Time-limited Downshift

The light will accumulate a lot of heat when used on High output level for extended periods. When the light has been used on High for 1.5 minutes, the light will automatically step down by a few lumens until 50 lumens is reached to reduce the temperature. High mode can be reselected.

Usage and Maintenance

  • Disassembling the sealed head can cause damage to the light and will void the warranty.
  • Fenix recommends using an excellent quality battery.
  • Fenix strongly recommends using high-performance Ni-MH rechargeable batteries to get the most out of this light. Alkaline batteries will reduce the runtime relatively.
  • 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.
  • 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 flashlight

  2. Daniel Doerrler (verified owner)

    Grabbed this flashlight because I needed a small pocket light for HVAC work in dark basements all the time. It fits in a shirt pocket way better than a pen because it is shorter. That’s a big upside to this light. The only real gripe I could give is the clip on it is very tight, making it difficult to put in/take out of my pocket. I imagine it will loosen up over time so I would rather it start tight than to start not tight enough. Overall happy with it👍

  3. Emil W. (verified owner)

    I got this little flashlight for my lady who works in a lab. She absolutely loves it!

  4. John F. (verified owner)

    Decent little light. Only complaint is the tail switch is a little sticky and doesn’t change brightness settings as crisp and reliably as I’d like.

  5. Charles O. (verified owner)

    Pretty happy with the purchase. Perfect EDC size in a jeans pocket. I did trigger the button switch in the pocket that killed the battery once. On high, running for several minutes (about 10) the body felt warm. Overall, it’s a great flashlight based on the size and the light output. Recommended by this guy.

  6. Mark (verified owner)

    Powerful compact light in the tradition of pocket pen lights.

  7. David Jacobsen (verified owner)

    Perfect Light fits in my pocket don’t notice it’s there plenty bright easy to use great flashlight

  8. Rafael Z. (verified owner)

    Great flashlight and super bright for the size!! Good when you don’t want to use your regular flashlight. It fits in any slot outside the tactical vest without taking too much space. Fenix always thinking two steps ahead.

  9. Anonymous (verified owner)

    Even more compact than its big brother, the LD05 and using only one AAA battery.

  10. Edward M. (verified owner)

    Love them! Got one for my wife too. Perfect for carry in any number of ways, so no reason to not always have it with you. Waiting for color filter lens caps. Then it will be even more perfect.

  12. James L. (verified owner)

  13. Israel Tamoro (verified owner)

  14. Lyman J. (verified owner)
