5. Battery and Charging
The FIVERAY M20 Combo is equipped with an internal battery. Battery runtime varies based on the power output setting:
- 20W Output: Approximately 40 minutes (at 4300K)
- 10W Output: Approximately 1 hour 20 minutes (at 4300K)
- 5W Output: Approximately 3 hours (at 4300K)
These figures are based on internal laboratory tests with the light fully charged. For extended use, especially at higher power settings, it is recommended to connect the light to an external power bank via its USB-C port.

7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the light's surface. Avoid using harsh chemicals or abrasive materials.
- Storage: Store the light in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: To prolong battery life, avoid completely discharging the battery frequently. If storing for an extended period, charge the battery to approximately 50-60%.
8. Troubleshooting
- Light not turning on: Ensure the battery is charged. Connect to a power source via USB-C and try again.
- Overheating/Automatic Shutdown: The light may reduce intensity or shut down if it detects excessive heat. This is a protective measure. Allow the unit to cool down. For prolonged high-power use, consider using it in a well-ventilated area or reducing the intensity.
- Short Battery Life: Battery performance can be affected by high power settings and environmental temperature. Ensure the light is fully charged before use. For longer sessions, use an external power bank.
- Inconsistent Brightness/Color: Check for any obstructions on the LED panel or ensure accessories are properly attached. If issues persist, perform a factory reset if available (refer to the device's on-screen menu for this option).
