Do you know that a led bulb glows when it encounters water without electricity? Yes,it will happen if the led bulb is an LED AC/DC Bulb with the battery and the water isn't the distilled. The principle is to use the good conductivity of water. Once the bulb has a battery and the water has the conductivity, the positive and negative poles of lamp can be connected to form a complete circuit.The battery then discharges causing the bulb to light up. This bulb must be an LED Smart Emergency LED Bulb with a rechargeable battery inside. When there is electricity outside, it will charge. When there is no electricity outside, it will detect whether the two poles are connected.If it is on,the light will come on. In a demonstration, the bulb's head is submerged in water, so that an internal detection circuit detects water resistance and triggers an electronic switch to light the bulb. Due to the high sensitivity of the detection circuit of the power failure emergency bulb, the resistance of about one hundred Ohms can be detected to light the bulb.Then not only the lamp cap will light up in the water, but if the skin of the finger is not too dry, the lamp head can also be lighted by touching the lamp head with the finger at the same time.You can try this to find something in the event of a sudden power outage. High-quality products, scientific knowledge, make life brighter. Welcome to learn more about Rongchang LED Lighting LED Bulb DC and AC.
