What is a common voltage for low-voltage residential lighting?

In residential settings, low-voltage lighting systems commonly operate at 12 or 24 volts. This lower voltage is advantageous because it poses less risk of electric shock, making it safer for use in various environments, including gardens and outdoor areas. Additionally, low-voltage systems can be more energy-efficient, allowing for the use of smaller transformers to step down higher voltage to the required levels. This not only reduces energy consumption but also enables flexible installation options, such as using smaller, less intrusive fixtures.

In contrast, typical residential outlets provide electricity at either 120 volts or 240 volts, used for standard appliances and larger equipment. While these voltages are efficient for powering most household devices, they are not categorized as low voltage. The other option of 48 volts is less common in residential applications, as it does not align with the typical design and usage patterns for low-voltage lighting systems.
