DC LED step lights are a type of LED step light that operates on a direct current (DC) power source. They are commonly used in low voltage lighting systems and are energy-efficient, durable, and long-lasting.

DC LED step lights are often powered by a transformer that converts the high-voltage AC power from the mains supply into low-voltage DC power suitable for use by the LED lights. The use of a DC power source ensures that the lights operate at a consistent and steady level of brightness, regardless of any fluctuations in the power supply.

One advantage of DC LED step lights is that they are typically more efficient than AC LED lights, as they require less energy to convert the voltage from the power source to the voltage required by the LED lights. This means that they are a cost-effective lighting solution for stairways and other low-voltage lighting applications.

It's important to note that when installing DC LED step lights, care should be taken to ensure that the correct voltage is used and that the wiring is installed correctly to avoid any safety hazards. It's always a good idea to consult a licensed electrician for advice and assistance with installation.
