Mode switching sequence:

White constant on → White flash → Red constant on → Red flash → Blue constant on → Blue flash → Green constant on → Green flash

Note: If the power is disconnected for more than 5 seconds, the light will turn on in the same mode as when it was last turned off.

Low Voltage Protection:

The product automatically identifies the battery type and applies corresponding low voltage protection:

When using a CR123A disposable lithium battery (voltage < 3.4V), when the battery voltage drops below approximately 2.0V, the output will automatically step down, and the light will turn off after approximately 10 minutes, entering sleep mode.

When using a 16340 rechargeable lithium-ion battery (voltage > approximately 3.4V), when the battery voltage drops below approximately 2.9V, the output will automatically step down, and the light will turn off after approximately 10 minutes, entering sleep mode. This helps prevent over-discharge damage to the rechargeable battery. For optimal performance, it is recommended to use a fully charged 16340 battery with a voltage above 3.6V to ensure proper battery type identification.
