You can use diffuse or IES lights, applied to spheres (in your Scenes folder) and position or tweak them.  A trick I've been using, but only when the ceiling will not show, is to apply a physical ceiling (or import and move a ground plane) and apply frosted glass to it.  It really diffuse the lighting.

I know others will pipe in with interior tricks as well...

For interior rendering, you may want to dig into the KeyShot preferences and enable 'experimental features'. Granted you're running KS 4.3.18.

This will enable a 'indirect bounces' slider in the project settings tab (beside 'ray bounces').
The default value is 1. When set to any higher value (2-4 will suffice) indirectly lit interiors (areas not receiving direct light, but bounced light...Very common in interiors...) will brighten up significantly.
Maybe you can start by using it on the default area light cornell box scene. The difference is huge!

thank you very much for your explanations.

I learned from you :)

I think a webinar would be useful to all those who use Keyshot for interior design projects.
