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 turned off for approximately 45 seconds, it will revert to flame mode. Flame Effect: The lamp simulates natural flickering flames using safe, energy-efficient LED technology with no open flame. Creates a realistic flame-burning effect without actual fire. High Quality and Safety: LED flame bulbs contain no harmful substances, produce no open flame, UV radiation, or infrared radiation, and are environmentally friendly. Designed with efficient heat dissipation for improved safety and extended service life. Decorative Use: Ideal for home decoration in bedrooms, living rooms, bars, outdoor gardens, cafes, weddings, parties, and more. For optimal flame effect, use with frosted glass bulbs and E27 sockets in table lamps, floor lamps, or wall sconces. Warm Tips: 1. Operate the bulb at rated voltage only. 2. The flickering flame bulb is not waterproof. 3. Always disconnect power before installing or replacing the bulb. 4. Mode changes are controlled by the power switch that operates the lamp, not by a button on the bulb itself.
