4 Modes: LED flame bulbs feature flame emulation mode, breathing mode, general illumination mode, and gravity-induced mode. The mode changes each time the bulb is turned on or off. After being turned off for approximately 45 seconds, the bulb automatically reverts to flame mode. Flame Effect: These bulbs simulate natural flames with realistic flickering, using safe, energy-efficient LED technology—no open flame, no UV radiation, and no infrared radiation. Safety & Quality: Made without harmful substances, the bulbs offer excellent heat dissipation for enhanced safety and extended service life. Decorative Use: Ideal for home decoration, bedrooms, living rooms, bars, outdoor gardens, cafes, weddings, and parties. For optimal flame effect, use with frosted glass bulbs and E27 sockets—such as table lamps, floor lamps, or wall sconces. Usage Notes: 1. Operate only at the rated voltage. 2. Not waterproof. 3. Always disconnect power before installation or replacement. 4. Mode switching is controlled via the power switch—not a button on the bulb.
