Brightness Modes & Runtime

Figures below come from our printed user manual and are measured per ANSI/PLATO FL1-2025. Values are approximate and may vary by flashlight, battery, and environment.

Strobe and SOS are also available. The manual lists a single throw figure (330 m) for the light. Turbo runtime includes the step-down in output caused by temperature regulation and protection mechanisms.

How Mission-Adaptive Power works: the light delivers full output at the start of use, then proactively steps down to a sustainable level to protect battery life and manage heat. Turbo is meant for brief, high-need tasks, not extended use.

Features & Benefits

• Highest output in the lineup: Up to 4,000 lumens, with a wider 18.7° beam for work-area lighting.
• Magnetic base: The tail cap locks onto metal surfaces for hands-free lighting.
• Safety Lock: A physical toggle switch locks the power button so the light does not switch on at full blast in a tool belt or bag.
• Mission-Adaptive Power (MAP): Delivers full intensity at the start of use, then steps output down to a sustainable level to protect battery life.
• Eco / Moonlight mode: A discreet 5-lumen mode for up to 150 hours, useful for stealth or when the battery is low.
• Memory mode: The light remembers your last brightness setting. This applies to the daily light modes; Strobe and SOS are not saved.
• Fast-Charge USB-C: Charge through the USB-C port on the battery.
• Strobe and SOS: Press and hold the power button while the light is on.
• IP68 and drop tested: Dual O-ring sealing keeps out water, dust, dirt, and oil; submersible up to 2 m; drop tested to 1.5 m.
• Aircraft-grade aluminum body: 6061 aluminum with Mil-Spec Type III hard-anodized finish, plus pocket clip and lanyard.

What's Included

Check your box for the following:

• 1 × XP40 flashlight
• 1 × 21700 rechargeable battery (4,500 mAh) with USB-C port

Setup Steps (First Use & Charging)

Requirements: a USB power adapter rated 5V, 1.5A or higher (not included) and the supplied USB-C cable. Charge fully before first use for an accurate read on runtime.

1. Unscrew the tail cap and remove the circular insulation tab from the battery before first use.
2. Twist the tail cap to access the battery. The battery has its own USB-C port, as shown in the manual diagram.
3. Using the included USB-C cable, connect the battery to a USB power adapter rated 5V, 1.5A or higher.
4. Watch the charging LED: it lights red while charging and turns green when fully charged (about 3 hours).
5. Disconnect the cable, put the battery back in the flashlight, and rotate the tail cap clockwise until it is fully closed to keep the waterproof rating.
6. Slide the toggle to the unlocked position, then press and hold the power button to turn the light on.

Good to know: the charging rate is limited to 1.5 A. Charge fully before first use, and use only the supplied USB-C cable. Do not charge unattended for extended periods.

Operating Your Flashlight

• Lock / Unlock: Push the toggle switch up or down to lock or unlock the light.
• On / Off: With the light unlocked, briefly press and hold the power button.
• Brightness: While ON, briefly press and release the power button to cycle: Moonlight → Low → Medium → High → Turbo (then it repeats).
• Strobe / SOS: While ON, press and hold to activate Strobe. While in Strobe, press again to switch to SOS.
• Memory mode: The light remembers your last brightness setting. Strobe and SOS are not saved.
• Battery check: While off, briefly press (or lightly press) the power switch. The indicator light shows the battery level for 3 seconds.
• Indicator: Battery indicator light: green = sufficient charge, red = low charge, recharge soon. While charging, the charging LED is red and turns green when the battery is fully charged.

Care & Maintenance

• Cleaning: Wipe the exterior with a soft, dry or damp cloth. No solvents, abrasives, or high-pressure washing.
• Seals: Periodically inspect and clean the O-rings and threads to maintain the IP68 rating.
• Charging port: Keep it free of debris and moisture before connecting the USB-C cable.
• Do not disassemble: Do not take apart the driver or battery compartment. Doing so voids the IP68 rating and the warranty.

Safety Information

• Charging: Use only the supplied USB-C cable and do not charge unattended for extended periods. After charging, close the flashlight by rotating the tail cap or neck clockwise so it keeps its waterproof rating.
• Battery: Do not disassemble, crush, heat above 100°C / 212°F, or incinerate the battery. Use only the OEM rechargeable Li-ion battery; another battery may present a risk of fire or explosion.
• Beam: Do not stare into the beam or point it at eyes, aircraft, vehicles, or people.
• Heat: The body and head may become hot on Turbo and High. Avoid prolonged skin contact.
• General: Keep away from unsupervised children. Use only OEM batteries and accessories. Changes or modifications not expressly approved by the manufacturer could void your authority to operate the equipment.

Troubleshooting

• The flashlight will not turn on

- Make sure the circular insulation tab was removed from the battery before first use.

- Check that the battery is charged and seated in the correct orientation, as shown in the manual diagram.

- Confirm the tail cap is fully closed (rotate clockwise).

- Slide the toggle to the unlocked position. Lockout disables the power button to prevent accidental activation.

• The light flickers, dims, or shuts off unexpectedly

- Low battery voltage or a loose battery connection are the most common causes. Remove and reseat the battery, then recharge it.

- High modes automatically step down to prevent overheating. This is normal Mission-Adaptive Power behavior; let the light cool and use a lower mode for long tasks.

• The light will not charge

- Try a different USB-C cable or power adapter first, and use one rated 5V, 1.5A or higher.

- Open the tail cap and connect the cable directly to the battery's USB-C port.

- Check the port for lint, debris, or moisture and clean it gently with a dry, soft brush.

- Look at the LED: red means charging, green means fully charged.

• The brightness will not change

- Make sure the light is ON and unlocked, then briefly press and release the power button. Holding the button starts strobe instead.

- Brightness cycles Moonlight, Low, Medium, High, Turbo, then repeats.

• Strobe or SOS came on by accident

- Press the power button again while in Strobe to switch to SOS, and again to exit. Strobe and SOS are not saved in memory, so the light returns to your last normal mode.

• The light gets hot

- The body and head may become hot on Turbo and High. Switch to Medium or Low for longer tasks and avoid prolonged skin contact.

• Turbo gets dimmer after a short time

- This is Mission-Adaptive Power. Output steps down from the initial peak to a sustainable level to protect the battery and manage heat.

• I want to check the battery level

- With the light off, briefly press or lightly press the power switch. The indicator shows the level for 3 seconds: green is sufficient, red is low.

• Runtime seems shorter than listed

- Runtimes are measured to the ANSI/PLATO FL1-2025 standard, are approximate, and Turbo runtime includes step-down. Real-world results vary with battery age, temperature, and mode.

- Normal battery capacity loss from charge cycles is not a defect.

• I am worried about water getting in

- Make sure the tail cap is fully closed, and inspect and clean the O-rings and threads periodically. Do not disassemble the driver or battery compartment, which voids the IP68 rating and warranty.

Usage & Tips

• Slide the toggle to lock before you toss the light in a tool bag.
• Stick the magnetic base to a steel panel, beam, or toolbox for hands-free work lighting.
• Use Medium (280 lm, 7.5 hours) for most job-site tasks; Turbo is best for short bursts.
• Keep the O-rings and threads clean and the charging port free of debris and moisture.
• Never point the beam at eyes, aircraft, vehicles, or people.
• Match the mode to the task: higher modes drain the battery faster and generate more heat.
