Do a simple search. I see lots on Amazon. Some folks here recommend 4000k. I find them too hospital-like. 3000-3500k is what my family prefers.

Thanks, my kitchen is dark, not much light from outdoor

Buy the trims anywhere, online or big box, but we never recommend over 3000. Use 15 watt and use more if you can.

Our electrician gave me the name of the LEDs to get from Amazon, he said they were less than he would pay at the electrical supply store. He also hooked them all up to a dimmer. 4K is really bright! this is the link

Then you need more lights, not simply a change in lightbulb color temperature.

I find 3000K perfect, can live with 3500K but don't like higher than that.

Are you confusing KELVIN (color) with LUMENS (brightness)?
