How many volts does an led use
Web16 aug. 2012 · Headlight lamps therefore are designed for 13.2 volts. If you apply more, the lamp shines brighter, but it ages considerably faster, too. Five percent excess voltage costs you 50 percent in lamp life! A lamp that runs continuously on 14.5 volts or more will soon burn out. Excess voltage is the most common cause of premature failure. WebLEDs must have a resistor in series to limit the current to a safe value, for testing purposes a 1k resistor is suitable for most LEDs if your supply voltage is 12V or less. Remember to connect the LED the correct way round. Please see below for an explanation of how to work out a suitable resistor value for an LED. LED Colours
