4 Modes: LED flame bulbs feature flame emulation mode, breathing mode, general illumination mode, and gravity-induced mode. When you turn the bulb on or off, the mode changes accordingly. If the bulb is turned off for approximately 45 seconds, it will automatically return to flame mode. Flame bulbs: The flame lamp simulates natural flames with flickering LED light, creating a realistic flame effect without an open flame. Safe, energy-efficient LED light source provides a lifelike burning appearance. High quality and safety: LED flame bulbs contain no harmful substances, produce no open flame, and emit no UV or infrared radiation. Environmentally friendly design with excellent heat dissipation for enhanced safety and extended service life. Beautiful decoration: Ideal for home decoration in bedrooms, living rooms, bars, outdoor gardens, cafes, weddings, and parties. For optimal flame effect, use with frosted glass bulbs and E27 sockets, such as in table lamps, floor lamps, or wall sconces. Warm Tips: 1. Flame bulbs must be used at the rated voltage. 2. Flickering flame bulbs are not waterproof. 3. Always disconnect the power supply before installing or replacing the bulb. 4. The mode change function is controlled by the power switch, not a button on the lamp.
