Whether you're starting from scratch in a new kitchen, or just deciding to switch it up - you'll need to cover the three lighting types. General, which provides basic light for the room; Task lighting, which highlights a specific work area; and Accent lighting, which can create a focal point in the room.
The location of counters and cabinets in the layout of the room is important when deciding placement of the fixtures.
Under cabinet lighting is a perfect type of task lighting while you're prepping your meals, or doing the dishes (Depending on where your cabinets are). Pendants over an island or peninsula is a great type of accent lighting - this can also blend into task lighting as well if you do cooking prep on this area as well!
If your dining room table is also in your kitchen, a chandelier or other large hanging fixture works as an accent light as well!
Overall, all types of lighting should be layered within a space to create a warm and inviting atmosphere while also being practical.
