Review (5/5): Great Value
These are frosted domes, not clear. Nice even light dispersion and light output values per color seem to be vary similar at similar input voltages to each of the pins. I've calculated that these LED's run at 3.0 to 3.4 Volts, using 18 to 20 Milli-Amps so use a matching input resistor. (Source Volts - LED Volts) divided by LED Current = Resistor Ohms ..... For Example, 5 Volts Input Minus 3.4 Volts LED = 1.6, 1.6 Divided into LED 0.020 Milliamps = 80, So in this case You would need an 80 Ohm Resistor if you were going to power this LED with 5 Volts.
