What is the ideal voltage for standard household lighting?

The ideal voltage for standard household lighting is 120 volts. This voltage level is commonly used in residential settings across the United States, including Rhode Island. This standardization facilitates the easy operation of typical lighting fixtures, appliances, and electronic devices that are designed to operate efficiently at this voltage.

Using 120 volts for household lighting ensures compatibility with a wide range of lighting options, such as incandescent bulbs, LED lighting, and compact fluorescent lights (CFLs). Additionally, the safety and accessibility of wiring at this voltage level have been well-established in electrical codes and standards, making it a reliable choice for home use.

Other voltage levels like 240 volts are typically reserved for larger appliances such as dryers and ranges, while 12 volts and 48 volts are often used in specialized applications, including automotive systems and low-voltage lighting installations, but they are not considered standard for typical household lighting. This is why 120 volts is recognized as the ideal voltage for standard household applications.
