I had 4 lights before and had to stop the render as I need my computer during the day for my photography. I was hoping to get the image rendered overnight. So after the image in the screenshot, I changed the iso to 100 and the shutter speed to...um don't remember but it was somewhere around 1/250s.

I read somewhere that the mesh lights slow down the computer badly. Is that correct?

For now I will take your advice aRtBee, you are very knowledgable (I saw your website's tutorials). I will make a smaller render to test the lighting, like you suggested so I can figure out the best lighting system for a portrait render. I wish I could find more tutorials for reality lighting.
