100 pcs blue LED 3mm clear, tinted.

Max. current (continuous) is 20mA, resulting in 3.2-3.6V forward voltage.

LEDs are operated at constant current, not voltage! It is necessary, to limit the LED forward current with a resistor. The value of the resistor is easy to calculate following Ohm’s law: R = U / I

For example, on a 12V power supply, U = 12-3.6 = 8.4V, I = 0.02A. The resistor in this circuit should not be less than 8.4 / 0.02 = 420 Ohm (for max. brightness). For battery operated applications, you should consider a much lower LED current, for example 3mA (equals 2.9kOhm on 12V).​​​​​​​

1 review for 100 pcs blue LED 3mm clear, tinted

I got these for a developmental project just to have a power load. I must say they are quite bright. I did not expect 20mA (~64mW) LEDs to be at all bright, I was pleasantly incorrect. For most uses of the LEDs they will never need to be at full power unless you are trying to make someone squint or have a very high amount of diffusion. I coupled two 25 sets in parallel (50 total) with a TL4242 for PWM brightness control and they are fantastically bright.
