Unity 5 Lightmap

Hii..

I am doing lightmapping but i have multiple spotlight and pointlight in my scene.

All lights are having different color , range and intensity.

But when i am selecting all lights togather and try to bake then result is not coming with exact light range and intensity.

So is it necessary to bake light with diiferent value separatly ?

Or i am doing some mistake? all lights baking attribute is set to "Baked".

Thanks.
