The latest version of Lumion 2.5 has 20 layers.
If you reduce the show cache from 512 to 256 it will again increase render speed, may not be too noticeable depending on how many lights are used, and it depends on scene and PC performance as well. All depends what you need for the scene, use higher shadow cache or dynamic if you are moving close in to lit areas and need the better quality.
If you have for example a day and night scene, then putting all the lights in a layer and hiding the layer for the day time scene will improve the render (almost, as if deleting the lights).
