All LEDs require current limiting, without a current limiting mechanism, LEDs will usually burn out in under a second. Voltage drop across a LED depends on a it's color, for blue led for example - 3.4V. This means that if there are 3 LEDs in series and each LED requires a 3V voltage drop, the LEDs will consume 9V of power. So, Iload is 0.075A If you want to connect 24V to a LED, there is no need to convert it to 12V. 10PCS,5mm FLAT TOP Wide Angle BLUE Flashing LED With 12V Free Resistor FF5B,amy.
