For Your Safety

• This product is not suitable for charging with a USB-A port.
• Use only the supplied USB-C power cable and connect only to USB-C port power (5V DC, 1.5A). Otherwise the lamp will fail to work normally or result in a fire hazard.
• In order to prevent damages to the lamp, do not hang or place any objects on the lamp.
• This product is suitable for indoor use only.
• Route the USB-C power cable so as to avoid it from being pinched by items placed upon it or against it.
• The light source of this lamp shall only be replaced by the manufacturer's service agent or a similar qualified person.

• This lamp has a built-in rechargeable lithium battery in the lamp body. Please pay special attention to the following items when using the lamp:

• Do not subject the lamp body to impact, drop, or place it in a high/low temperature environment (such as near a fire (heat) source or in a closed car under the sun), so as to avoid fire caused by battery damage or high heat or explosion.

• If the lamp is not used for a long time, charge it at least once a month to avoid battery damage due to over-discharge.
• Rechargeable batteries are consumables and their capacity will gradually decrease with time and the number of times they are used. This is a normal phenomenon.
• When traveling by air, remember to put this lamp in your carry-on luggage, not in checked luggage.

CAUTION

• In case of the following situations, unplug the lamp from the USB-C port immediately and contact the authorized service center or a qualified service person for inspection or repair:
• When the outer casing of the lamp is broken
• When there are strange odors coming from the lamp
• When the LED light source flickers
• When the insulation of the USB-C cable is damaged or frayed, and the metal strings inside can be seen
• Do not use the lamp in a humid environment (like in a bathroom). Otherwise the components inside may short-circuit and result in hazards.
• Never disassemble the lamp or remove any components from it, as doing so may result in hazards and will void the product warranty.

Installation

Affixing the Magnetic Patch

This lamp employs magnetic technology to attach the lamp body to the lid of your laptop computer. Follow the instructions below to affix the magnetic patch included in the package to the lid of your laptop for attaching the lamp body.

1. Close the lid of the laptop computer. Use the cleaning cloth included to clean the lid and make sure that there is no grease and dust residue so as not to affect the firmness of the magnetic patch.

2. Align the Instructions Card for the Magnetic Patch with the top edge of the lid of the laptop computer (non-hinge side) and position the semi-circular positioning opening so that it is in the center of the lid.

3. Peel off the liner on the back of the magnetic patch and then place it in the semi-circular positioning opening. When affixing the magnetic patch, note that the lower edge of the magnetic patch must face the hinge of the laptop computer and press the magnetic patch evenly with your fingertips.

4. After affixing the magnetic patch, let it rest for 20 minutes. During this period, do not place the lamp body on the magnetic patch so as not to affect its firmness.

If there is no Instructions Card for the Magnetic Patch for affixing and positioning the magnetic patch, refer to the position of the magnetic patch as shown in the figure (2.5 cm from the edge of the lid of the laptop computer).

Installing the Lamp Body and Lamp Head

This lamp provides two installation forms for the lamp body. Choose one according to your preferred light effect.

Folded Form

1. Open the lid of the laptop computer.

2. Facing the screen of the laptop computer, hold the lamp body so that the side of the lamp body with two positioning grooves faces you and make the lamp arm on the right side of the lamp body.

3. Place the lamp head on the upper end of the lamp body so that the lamp head is magnetically attached to the lamp body.

4. Place the lamp head on the upper end of the lamp body so that the lamp head is magnetically attached to the lamp body.

5. Slowly move the magnetic area on the lamp body towards the magnetic patch affixed on the lid of the laptop computer until the lamp body is firmly attached to the magnetic patch.

6. Adjust the position of the lamp body so that the positioning groove on the upper end of the lamp body is flush with the upper edge of the lid of the laptop computer.

7. Adjust the angle of the lamp head according to the needs. The larger the angle of the lamp head, the better the light effect.

8. Place the lamp head on the upper end of the lamp body so that the lamp head is magnetically attached to the lamp body.

9. Slowly move the magnetic area on the lamp body towards the magnetic patch affixed on the lid of the laptop computer until the lamp body is firmly attached to the magnetic patch.
10. Adjust the position of the lamp body so that the positioning groove on the upper end of the lamp body is flush with the upper edge of the lid of the laptop computer.
11. Adjust the angle of the lamp head according to the needs. The larger the angle of the lamp head, the better the light effect.

If your eyes will look directly at the light source, it is recommended that you reduce the angle of the lamp head or change to the Extended Form.

Connecting the Power Cord (Charging)

Fully charge the lamp before using it for the first time. Connect one end of the included USB-C power cable to the USB-C charging port on the lamp body and the other end to the USB-C port of your laptop computer or charger to start charging.

• This lamp is not suitable for charging with a USB-A port. Insufficient power supply will cause the lamp to flicker.
• Connect only to a USB-C port that can provide power above 5V/1.5A to ensure that the charging function works properly.
• This lamp cannot be used as a mobile power supply so do not connect any other devices to the USB-C charging port on the lamp body.
• After fully charged, the lamp can provide about 100 minutes of use time when the color temperature is set to the middle and the brightness is set to the brightest level.
• If the battery is exhausted, it will take about 150 minutes to fully charge the battery using a USB-C port with a power supply above 5V/1.5A.
• When charging, remove the lamp head from the lamp body to achieve a faster charging speed.
• If you use the lamp while turning it on and charging it at the same time, it will take more than 150 minutes to fully charge the battery. The higher the lamp's brightness, the less wattage is left for charging, and the time to fully charge the battery increases accordingly.

Power Indicators

There are 4 power indicators on the lamp body to display the charging status and the remaining power level of the battery. Refer to the following table for the status and meaning of the power indicators:

Status Meaning/Troubleshooting guide
	Powering up (remaining power level: 3)
	Charging (charged power level: 2)
	Battery is exhausted.
	Error occurred during charging. Use the included USB-C cable and connect to a USB-C port that supplies power above 5V/1.5A.
	Battery temperature is abnormal. Stop using the lamp, the light will stop flashing after the temperature returns to normal, and the lamp can be used again.
	Internal error. Stop using the lamp and contact customer service personnel for assistance.

Using the Lamp

Turning On/Off the Lamp

Slightly wave your palm within about 2 cm from the On/Off Sensor on the top of the lamp head to turn on/off the lamp.

The lamp will memorize the setting before power off. Detach the lamp head from the lamp body to turn off the power. Attach the lamp head to the lamp body to turn on the power.

Maintenance and Troubleshooting

• Turn off the lamp first, and unplug the lamp from the USB-C port. Wipe any smears or dusts off the lamp's outer casing using a soft, lint-free cloth lightly moistened with a mild detergent solvent. Do not use alcohol or any other chemical solvents like kerosene, naphtha and so on, as the lamp's casing may become damaged.
• Do not rinse the lamp or any of its components directly with water.
• If the lamp does not turn on, check to make sure that there are no loose connections between the USB-C cable and USB-C ports.
• If the problem persists, please contact the original place of purchase for help.
