Anti aliasing area light

I'm using Kray 2.2 with layout 2015.1

The render I'm getting is great except where the area light hits the wall. You can see aliasing or stepping in the image. I have the area light set to Compute with luminosity
Image

It doesn't seem to matter what settings I change they remain consistent. Any tips on eliminating that?

Thanks
Doug

I may have answered my own question... I upped the light samples to 6 (in the render globals panel) and the problem seems to have cleared up.

In this corner You can use:
- Area Light (actual in scene) but then you must increase Area Light Quality and render long
- LEM - just luminosity panel - then is better render in QMC mode.

Here setting for minimum quality for Area Light:

Here maximum quality (over that is unprofitable raising amount of rays):

I suggest to use QMC system and LEM lights. In this moment the best option for rendering.

Thanks for the response.

Forgive my ignorance but I can't seem to find any info on LEM. Is that a KRAY thing? Or simply a luminous polygon in Lightwave?

LEM = Light Emitting Material = Luminous polygon in Lightwave

LEM:

If you want hide LEM in scene (only light will be visible, like Area Light):

1.Select in Kray GUI Unseen by Rays Casts Light

2.In LW select Unseen:

Your LEM starts be invisible, giving only light.
