How To Use 3v Led On 12v. But that same 12V battery wired to four 3V LEDs in parallel would deliver the full 12V to each LED - enough to burn out the LEDs for sure. Answer 1 of 9.
Anyway LED operation is defined by the current that flows through them not the voltage across them as such. For example a red LED will need a FV of 12 V a green Led will require 16 V and for a yellow LED it is around 2 V. This works it is just a lot of wasted power.

High-power LEDs can take currents from 350mA to 3000mA. Simulate this circuit Schematic created using CircuitLab. 33v 33v LED how to connect 12V series circuit how to calculate led se. So a 12V battery wired to four 3V LEDs in series would distribute 3V to each of the LEDs.
