Notes: This product is made of ceramic tungsten wire that emits light. Power supply: DC5V USB interface, current: >1A, must not exceed 2A, otherwise the circuit board may be damaged. Tested for 6 hours without causing overheating. It is an electrical appliance. Pay attention to waterproof safety during use. Any improper operation is the responsibility of the user. The product must not be used in contact with water, and the glass shell must not be forcibly opened. The reason for the initial flicker after insertion is that the capacitive sensor receives sudden current input, causing a brief flash upon power-on. This may also occur if the LED bulb is shaken, but it will not happen again once properly inserted and fixed. When using multiple bulbs on the same power supply, since each bulb is controlled by a micro current, lighting one bulb may cause others to activate simultaneously. It is normal for multiple bulbs to turn on or off at the same time.
