Using too many lights will slow down everything a lot. Using more than 8 lights is a nono.
Instead increase the lights radius. Use lightmaping for the static meshes. Expect to touch some physical limits with multiple dynamic light source entities. Think about to use some other methods such as sswifts shadow system.
