That's strange, I can't replicate this problem in 3.50.04. Maybe the light is still partially inside the housing of that lamp? Did you try to move the disc light just a bit lower? Don't rely strictly on the viewport, sometimes it doesn't represent very accurately which objects are in front.

yes, hv tried before, but same.
below image that light pink color circle with some thickness(for easier to show the size)

Ok, from you're new screenshot I see you're using the Scale tool in Max to resize your lights which is a no-no. Scale back your light to 100 100 100 in X Y Z and only use the Radius parameter in the Vray light object to change its size. This should solve your issue.

yes, but right side that 2 plane light i got scale too, render look correct.
plane light i always use scale tool, coz sometime like cove light, not square, different length, if not instance, hard to adjust intensity, temperature and etc.
this time got many different size round shape light. btw, if this problem cant solve, i will just apply light material to the object.

i tend to scale my plane lights as well, it allows to have instanced lights while having different shapes/sizes, it`s very useful.
