The WinXPLuna is a theme for only specific set of controls and it's part of the Miscellaneous theme pack which is a mix of different themes all applying for only a small set of controls.
The WinXPLuna theme can be applied to: RadButton, RadCheckBox, ScrollBar, ScrollViewer and TabStrip.
I hope this will help. If you have further questions I would be glad to help.
