One metric is lumens at the counter for task lighting. 450 is the minimum recommended. This isn't the rated output. You have to consider distance from the fixture and spread based on the spread of the light output: usually flood, narrow flood or spot. Led output also comes in different levels of 'whiteness' from warm 2400k to 5000k bright white. A task oriented recessed 4" led can is often positioned 6" in from the edge of the counter to avoid a shadow from your body. In some locations undercabinet leds can contribute to task lighting.

Here is article on “layered” lighting. Make sure any bulbs are “dimmable”.

Opps. It wouldn’t post. Just googled “layered lighting” for good tips. You need all types in kitchens. Undercabinet, can lights, spots where needed such as on decorative cabinet and accent lighting such as pendants over islands. Design wiring to keep each source on a separate circuit. That way you can have only undercabinet lighting on in evenings for example and others off. Ceiling lighting is the harshest, so use as needed only.

Great information Flo, thank you so much.

Great information for me thank you, much appreciated.

Good lighting is essential for any kitchen, especially if you're planning to do a lot of cooking and other activities in the room. Here are some tips and suggestions for choosing the best lighting for your new kitchen:

Choose bright, white light bulbs: Bright, white light bulbs can help to create a clean and modern look in your kitchen, and they also provide ample lighting for cooking and other activities. Look for bulbs with a color temperature between 3500K and 5000K, which will provide a crisp, cool light.

Install task lighting: Task lighting is important in the kitchen because it provides focused lighting for specific activities like chopping vegetables, reading recipes, or working at the countertop. Consider installing under-cabinet lighting or pendant lights above the kitchen island to provide task lighting where you need it most.

Don't forget about ambient lighting: While task lighting is important, ambient lighting can help to create a warm and inviting atmosphere in your kitchen. Consider installing dimmable recessed lighting or a central fixture like a chandelier or pendant light to provide ambient lighting.

Consider natural light: If possible, try to incorporate natural light into your kitchen design. Large windows or a skylight can provide ample natural light during the day, which can help to reduce your reliance on artificial lighting.

What is this chap bot doing in the forums?

Yeah, testing it's software. Slammed a whole bunch of threads with internet excerpts.

@dormmom, your question is very general. Here is an excellent guide to understand the generalities of lighting, not mine nor shilling for: Danny Warfel: Language of Light

Once you work in a space with good levels of task lighting you notice how poorly designed kitchen lighting generally is.
