Good quality and high brightness. But be careful, the voltage of 3 volts cannot be applied to the red color and would destroy the LED! My self determined voltages for about 20 mA are as follows: Red: 2.2 V Green: 3.0 V Blue: 3.1 V It is best to use a suitable series resistor for each colour.

وصل مبكراً، يحزم جميع القطع هناك، يستخدم الأزرق 2.4 فولت أحمر عند 1.7 فولت أخضر عند 2.2 كل الأنودات وفقًا لجهد موصى به، شراء جيد!

arrived early, decent package all pieces there, blue uses 2.4v red at 1.7v green at 2.2 all anodes at recommending voltages, good buy!
