Advantages of low-voltage lamps: safety: low-voltage lamps are generally 12V/24/36V, which are all safe for human body to withstand voltage. Use in places with a high safety factor. Longer life: Because the circuit is DC low voltage, fewer components are used and the life is longer. No flicker. Since the DC voltage is used, the stroboscopic phenomenon in AC use is avoided. Small size: The volume can be made as small as possible because it does not require complex circuits. Disadvantages: It needs to be connected to a low voltage, which is not common with the 110V or 220V. Warm Tips: These are low-voltage lamps. Please confirm the voltage of your home equipment to avoid unnecessary trouble when you choose the products.
