Fenix LD02 V2.0 Reference ManualUpdated an hour ago

The Fenix LD02 V2.0 is an EDC penlight with a dual white/UV light source. This summary is drawn from the manufacturer's official user manual — see the downloadable PDF reference manual on the product page for complete details.

Overview

Cree XQ-E HI LED (90-CRI, 3000K), with a lifespan of 50,000 hours.
Fitted with a 365nm UV LED.
Powered by one AAA battery.
Digitally regulated output maintains constant brightness.
Reverse polarity protection to protect from improper battery insertion.
Tail switch for one-handed activation and output selection.
Made of durable, high-strength, oxidation-resistant aluminum and stainless steel.
Premium type HAIII hard-anodized anti-abrasive finish.
Optimal quality optical lens.

Operating Instructions

On/Off: Fully press the tail switch to turn the light on or off.

Output Selection: With the light switched on, tap the tail switch to cycle through Low → Med → High → UV.

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, it will automatically step down by a few lumens until 50 lumens is reached, to reduce the temperature. High mode can be reselected.

Battery Specifications

Ni-MH Battery, AAA, 1.2V — Recommended.
Alkaline Battery, AAA, 1.5V — Usable.
Lithium Battery (Non-rechargeable), AAA, 1.5V — Usable.
Li-ion Battery (Rechargeable), 10440/10450, 3.7V — Banned.

Warning: When the voltage level drops below a preset level, the flashlight is programmed to downshift to a lower brightness level until Low output is reached. To ensure normal use, the flashlight will not turn off automatically and will work until the battery runs out completely.

Battery Replacement

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

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, since dirty contacts may cause the lamp to flicker, shine intermittently, or fail to illuminate. A) Battery needs replacing: replace the battery (ensure it is inserted according to the manufacturer's specifications). B) Threads, PCB board contact, or other contacts are dirty: clean the contact points with a cotton swab soaked in rubbing alcohol. If neither resolves the issue, please contact your authorized distributor.

Warning

Do NOT shine the light directly into the eyes of anyone.
Do NOT shine the light at flammable objects at close range, to avoid burning objects or causing danger due to high temperature.
Do NOT use the light in inappropriate ways such as holding it in your mouth — this could cause personal injury or life-threatening harm if the light or internal battery fails.
This light will accumulate a lot of heat while working, resulting in a high temperature of the flashlight shell — pay attention to safe use to avoid scalding.
Turn off and lock the light, or remove the battery, to prevent accidental activation when the light is placed in a closed, flammable environment such as a pocket or backpack.
The LED of this flashlight is not replaceable, so the whole light should be replaced when the LED reaches the end of its life.

Technical Parameters

High: Output 70 lumens, Runtime 40 min* (alkaline) / 45 min* (Ni-MH), Distance 48 m, Intensity 580 cd
Med: Output 25 lumens, Runtime 2 h 40 min (alkaline) / 2 h 55 min (Ni-MH), Distance 27 m, Intensity 185 cd
Low: Output 1 lumen, Runtime 75 h (alkaline) / 45 h (Ni-MH), Distance 6 m, Intensity 10 cd
UV Light: Output 200mW, Runtime 4 h (alkaline) / 3 h (Ni-MH)

All modes: Impact Resistance 1 meter, Waterproof IP68 (underwater 2 meters). Note: the above parameters (lab-tested by Fenix using AAA alkaline and Ni-MH batteries) may vary between flashlights, batteries, and environments. *The runtime of High output is the accumulated time when time-limited downshift activates.
