LEDs may still be affected by certain temperatures, which may affect their … Nettet6. des. 2024 · I know the LED won't light at all if you go much below its Vf, but how about above? Say a Cree R2 with a Vf of 3.7V will that tolerate, say 4.8V if I limited it to 350mA ? If you control the current, the LED will drop the 3.7V and pass the remaining voltage on to the rest of the circuit. Feb 16, 2009. #4.
