The answer to 'dimmer switch vs' is that a dimmer switch and a standard light switch serve different purposes and have different features. A dimmer switch allows you to adjust the brightness of a light, while a standard switch simply turns the light on and off.
Dimmer switches are typically more expensive than standard switches, but they offer greater control over lighting levels and can help save energy by reducing the amount of electricity used. They are commonly used in living rooms, dining rooms, and bedrooms where you may want to create different lighting moods. Standard switches are more basic and are often used in hallways, closets, and other areas where you don't need to adjust the brightness.
