Sorry for the confusion. Our site shows only only those options that are ready to ship. XPE Red cannot produce white.
We are working to expand special color options (red and possibly green and blue) and the first box of red happened to show up before the first box of white. People are waiting on them, so I posted them promptly.
A box of white is en route and expected to land this weekend, sat or mon. They will be available by next week, appearing as their own LED option in the Engine/Head menu.
