What are the best ways to optimize the placement and functionality of lights in a kitchen?

To optimize the placement and functionality of lights in a kitchen, consider using a combination of overhead lighting, task lighting, and accent lighting. Install recessed lights or track lighting for general illumination, under-cabinet lights for task lighting, and pendant lights or sconces for accent lighting. Make sure to position lights strategically to minimize shadows and glare, and use dimmer switches to adjust the brightness as needed.
