Who knows if we have any material about the introduction of LIFX interface?

Hi there,
I am using the interface “TransitionLampState” for LIFX 800 on linux system. and found this interface has some properties for example “Brightness”, “ColorTemp”, “Hue” etc. and I want to know if we have the materials introducing the related interface(including other interfaces) and where I can get it ?

thanks.

Makes no sense to me.
