Do I have to use the entity "light" or "light_spot"?
Are there any good tutorials esp. for light_spot?

for indooring i would use the normal light depends when you need to save alot of entitys i would do them with textlights or preferable choose textlights for better adjustments.

with spotlights you just get somekind of a cylinder light only so it would fit better for outdooring stuff like a streetlamp or so.

A combi between env_glow and light_spot is the best way devian.
