Over kitchen sink lighting refers to any type of lighting fixture that is installed above or near the kitchen sink area to provide illumination for cooking, cleaning, and other kitchen tasks. This type of lighting is essential for providing adequate task lighting and making it easier to see what you're doing while using the sink. Over kitchen sink lighting can take many forms, including pendant lights, track lighting, recessed lighting, under-cabinet lighting, or wall sconces. The type of lighting you choose will depend on your personal preferences, the style of your kitchen, and the amount of light you need in the area.
