• 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.
