Bathroom fans are available with and without built-in lights. A fan-light combo can simplify the ceiling layout, but a fan without a light may be cleaner and easier in some installations.
A fan with an LED light makes sense when your existing fan already has a light or when you want one ceiling fixture to provide both ventilation and illumination.
A fan without light may be better if the bathroom already has good lighting. It can let you focus on CFM, sones, duct size, and installation fit.
Fan-light combinations may require separate switches if you want independent control. Some installations may need wiring changes.
Bottom line: choose a fan with light if you need a combined fixture. Choose a fan without light if you want simpler installation and already have enough lighting.
