Can i import maya's light into unreal4

As far as I know, you can not.

The best you can do is to recreate any point lights, directional lights, spot lights, and try to copy any settings over (color, intensity, relative position, etc).

I found some many awesome maya light what can not find in unreal engine 4 . so in my case is threre any way to import maya’s lights into unreal engine 4

Hi there!
As far as I know not directly, (via FBX or so) but you can use Maya Live link, (that will give you transforms and intensity)
