Compact Fluorescent Lamps (CFLs) typically operate at voltages ranging from 100 to 277 volts, depending on the specific model and intended use. The most common voltage requirements for CFLs are:
120 volts: This is the standard residential voltage in many countries, including the United States and Canada.
220-240 volts: This is the standard residential voltage in many European countries and other regions.
It's important to note that CFLs often come with built-in electronic ballasts, which help regulate the voltage and current to the lamp. These ballasts are designed to work within the specified voltage range and provide the necessary starting voltage and current for the CFL to operate efficiently.
Before installing CFLs, it's crucial to check the voltage specifications on the packaging or in the manufacturer's documentation to ensure that they are compatible with the electrical system in your area. Using CFLs with incorrect voltage can lead to poor performance, reduced lifespan, or even damage to the lamp and your electrical system.
