I was able to find a solution after researching on Dynamic Shadows, Cascaded Shadows, Spot Lights, and Directional Lights settings. My solution was to make my one and only directional light in the scene cast no shadows, have 0 intensity, while still keeping ‘Atmosphere Sun Light’ and ‘Light Shaft Bloom’ turned on. Then I created a spot light for each ceiling fan and put it above the mesh so it can cast shadows. For the spot lights, I turned ‘Cast Translucent Shadows’, ‘Dynamic Indirect Lighting’, and set ‘Indirect Lighting Intensity’ to 4. Also turned on ‘Use RayTraced DistanceField’ and then I change the ‘Mobility’ to Movable. Now I have beautiful lighting from the ceiling fans! 
Here’s some screenshots, the shadow have no LOD and you can see it far away from it. It’s also a little bit more efficient - both performance and quality wise.
