But presumably, this works out to an average current of 20mA or less, even if the peak is higher. Again, if memory serves, these are pulse width modulated, and I don't recall the duty cycle.

The purists will note that these LEDs really are meant to be run at 20mA. In fact, if you can simply hold a 200 ohm resistor in parallel with one of the resistors (100 in parallel with 200 gives 66 2/3 ohms) to see if it makes much of a difference. I'd suggest you try doing one first to see if you think it's worth the effort. However, because the human eye is logarithmic in it's response, you will probably only perceive it as being a little brighter. That is: (5V-3V)/.03A = 66 2/3 ohms There nearest standard value is 68 ohms.
The red backlighting indicates standard keys that are not programmable, while the amber color indicates custom-programmable macro keys in game mode that can be tuned to the gamers’ preference. But if you want to take full advantage of the available current, you want to up this to 30mA. Research shows many gamers like to dim the lights, and the X6’s two-color adjustable backlighting helps set the mood to achieve total immersion. If you don't change the resistors, this would give a current of 20mA.
03A = 30mA White LEDs typically drop about 3V. Thank God Royal Kludge went with single color LED for the rev 2.0 board, since I despise the rainbow colored LED on Rev 1.0. I just realized that the X6 has the same problem, as well as a similar media key layout.

(Should be marked brown-black-brown if I'm correct.) Assuming a 5V supply, and a forward voltage drop of about 2V for the red LEDs, that gives a current of: (5V-2V)/100 ohms =. How To Use Microsoft Sidewinder X4 Keyboard Manual. If memory serves (I lent out all of my X4's), the resistors are 100 ohms each.
