The voltage required for an LED (Light-Emitting Diode) line light can vary depending on the specific type of LED and its design. However, most common LEDs typically operate within a voltage range of 1.5 to 3.5 volts. It is important to note that LEDs are diodes and are driven by current, not voltage alone. To ensure proper operation and longevity of an LED line light, it is essential to use an appropriate current-limiting resistor or a dedicated LED driver circuit that matches the specifications of the LED. These components help regulate the current flowing through the LED, preventing excessive current that could damage the LED. Therefore, when using an LED line light, it is advisable to consult the manufacturer’s specifications or product documentation for the recommended voltage and current requirements.
