What resistor do I need?

200 omh

For a white LED, the voltage drop is in the interval 3.4V to 3.6V, leaving 1.4V to 1.6V for the resistor. For 20mA, this gives a resistor of 70 to 80 Ohm. The nearest larger standard resistor in E-12 row is 82 Ohm which will give 17.0mA to 19.5mA.

For 200 Ohm, you need to use E-24 resistors (usually costs more), you'll get only 7mA to 8mA and hence much less light.

Other than that, it's nice for a little light on the keyboard, if you're sitting in the dark - I have made one that goes on top of my screen, and with a shade made of aluminum foil from a single use cake form :)

It depends on the LED power.
