Frequently Asked Questions - WL 1500 4K5

How to charge the WL 1500 lamp?

Use the supplied USB-C cable (not included in the manual, but standard). Plug the charger into a mains socket (not supplied). The operation indicator flashes during charging and turns off or stays steady once charging is complete. Full charge takes approximately 5 hours.

What is the battery runtime?

The runtime varies depending on the light level: FloodLow (~45 lm): about 139 hours, Medium (~320 lm): about 20 hours, High (~660 lm): about 9 hours, Boost (~1500 lm): about 5 hours.

Can the lamp be used while charging?

Yes, you can use the lamp while it is charging. However, the charging time may be slightly extended.

Is the lamp waterproof?

The lamp has an IP X5 protection rating, which means it is protected against water jets. It can be used in the rain but must not be submerged.

How to attach the lamp to a metal surface?

The lamp is equipped with powerful magnets in its suspension bracket. Simply bring it close to a clean metal surface. Beware of magnetic fields: keep a distance of at least 30 cm from medical implants, bank cards, etc.

What is Boost mode and how to activate it?

Boost mode delivers maximum power of 1500 lumens for intense illumination. It is likely activated by a long press or an additional press of the power button. Refer to the complete manual for exact instructions.

How to clean the lamp?

Use a slightly damp cloth to clean the surfaces. Never use cleaning agents, solvents, or abrasive products, as they could damage the housing or seals.

What to do if the lamp flashes abnormally?

If the indicator flashes while the lamp is not charging, it indicates a low battery. Recharge it. If the flashing persists after charging, contact customer service.

Is it dangerous to look at the LED?

Yes, never look directly at the light source. The lamp is classified as RG 1 (low risk), but prolonged exposure can cause glare, afterimages, or visual discomfort, especially in the dark.

Is the battery replaceable?

The Li-ion battery is built-in and not intended to be replaced by the user. If an issue occurs, contact the manufacturer or an authorized service. Do not attempt to open the housing.

Intended use

The product is intended for illuminating work areas. The work lamp has a floodlight with four light levels, red light and flashing red light. The light head can be swivelled by 180°. The suspension bracket is equipped with magnets for attaching to metallic surfaces. A 1/4" thread is available for fixing to tripods. The device is charged via the USB-C interface. An integrated power bank is used to charge mobile devices.

General safety instructions

• The device must only be used in accordance with its intended purpose and within the scope of the specifications.
• The appliance and its accessories are not toys for children.
• Modifications or changes to the device are not permitted, this will otherwise invalidate the approval and safety specifications.
• Handle discharged batteries with care. Battery packs are a source of danger as they can cause very high short-circuit currents. Even if Li-Ion battery packs appear to be in a discharged state, they never discharge completely.
• Avoid physical impacts.
• Impacts, force and penetration of objects can damage the batteries. This can lead to leakage, heat and smoke generation, ignition or explosion.
• A short circuit between the battery pack electrodes may result in burns or fire.
• Protect the battery pack from heat as well as permanent sunlight and fire, e.g. do not leave it in the car in summer, as this can cause explosions.
• Charge the battery pack at ambient temperatures between -10^ and 40^ .
• Do not expose the device to mechanical stress, extreme temperatures, moisture or significant vibration.
• The optimum charge level is between 50 % and 80 %.
• Use the mains/charger unit only inside closed rooms, do not expose to moisture or rain, otherwise there is a risk of electric shock.
• Fully charge the battery before using the unit.
• Charging is complete when the power indicator flashes.
• If the battery is weakly charged, the power indicator flashes.
• The battery can also be charged during operation.
• After charging, remove the charging cable and disconnect the power supply unit from the mains.

Safety instructions

Danger - powerful magnetic fields

• Powerful magnetic fields can adversely affect persons with active medical implants (e.g. pacemaker) as well as electromechanical devices (e.g. magnetic cards, mechanical clocks, precision mechanics, hard disks).
• With regard to the effect of powerful magnetic fields on persons, the applicable national stipulations and regulations must be complied with such as BGV B11 §14 „electromagnetic fields" (occupational health and safety - electromagnetic fields) in the Federal Republic of Germany.
• To avoid interference/disruption, always keep the implant or device a safe distance of at least 30 cm away from the magnet.

Safety instructions

Dealing with electromagnetic disturbances

• The device complies with the provisions and limit values for safety and electromagnetic compatibility in accordance with the Low Voltage Directive (LVD) 2014/35/EU and the Electromagnetic Compatibility (EMC) Directive 2014/30/EU.
• Local operating restrictions – for example, in hospitals, aircraft, petrol stations or in the vicinity of people with pacemakers – may apply. Electronic devices can potentially cause hazards or interference or be subject to hazards or interference.

Safety instructions

Using artificial, optical emission (OStrV)

• Do not look into the radiation source.
• Temporary irritating optical effects (e.g. glare, (e.g. glare, flash blindness, after-images, impairment of colour vision) cannot be completely excluded. especially at low ambient brightness.
• The unit operates with light sources of risk group RG 1 (low risk) according to the valid standards for photobiological safety.
• The light source does not pose a hazard when used as intended.

Information on maintenance and care

Clean all components with a damp cloth and do not use cleaning agents, scouring agents and solvents. Remove the battery(ies) before storing for longer periods. Store the device in a clean and dry place.
