Set of 50 LEDs in two sizes, 3 and 5 mm. Comes in an anti-static bag.

3 mm LEDs:
5 x red, 4 mcd, 2.3 V, 20 mA.
10 x ultra-white, 2000 mcd, 3.2 V, 20 mA.
10 x ultra-blue, 1000 mcd, 3.2 V, 20 mA.

5 mm LEDs:
5 x red, 12 mcd, 2.2 V, 20 mA.
10 x red, 6370 mcd, 3 V, 20 mA.
10 x ultra-blue, 3500 mcd, 3.6 V, 20 mA.


When wiring LEDs a resistor must be incorporated in order to limit the driver voltage. Calculate the required resistance by subtracting driver voltage from the LED's rated voltage and dividing this by the LED's rated current. Round up the sum to the nearest highest resistance value.
LED driver voltage -Rated voltage


= Resistance
LED rated voltage

Example: 12 V driver voltage and 3.6 V ultra-blue 5 mm LED:
12 V-3.6 V


= 420 ohms (nearest highest resistance value = 470 ohms)
0.02 A (20 mA)
