Tip: LED drive is based on the current value, not on the voltage.
If you use voltage drive, please confirm whether the current is normal, the current is too low will make the brightness drop, the current is too high will cause the LED chip breakdown or affect the service life, with voltage drive must add current limiting resistors to adjust the current.
The forward voltage of the LED will vary to some extent, Red、Yellow、orange、 yellowgreen voltage are in 1.8-2.4V, EmeraldGreen、 blue、 white voltage are in 3.0-3.6V
The forward current is generally 20mA.
