emission color: white
view angle: ±15°
forward voltage: 3.0V-3.3V(Max 3.8)
peak emission wavelength: na
luminous intensity: 10,000-12,000 MCD
lifetime : 100,000 hours
reverse current : 20mA
added info: Water clear lens
what type of a resistor would i need for that????
its a led....

The one in bold. Voltage drop means how much does the led take to power it. In this case, use 3.8 volts.

so it would look like this??
Supply Voltage
VOLTS 3.0
Voltage Drop Across LED
VOLTS 3.8
Desired LED Current
MILLIAMPS 20

No. Instead of 3.0 put 5.0. That's how much volts you are using to power the leds.
