Lot's of work gone into this I drafted too many setups on this and this one was not bad only if keyshot was more forgiving on the lighting

What rendering background do you have, KeyShot is very accurate with it's lighting. If you're used to a none HDRi based ambient light set-up then you can use the all black HDR in the environments tab, then you can place planes and discs where you want and you can set them to be Area Diffuse lights and point lights etc. If you need more realistic results than lighting planes you can use IES lighting too.

I used IES Lights but it takes ages to get them looking right is what i ment with my saying , but if the movments of the lights is a bit hard , If a light target dummy was included it would of improve the workflow speed
