I like even higher like 5000K in bathrooms the lower the number the more yellow cast from the light

Color Temperatures of Light Bulbs

Aside from the type of the light bulb itself, using Kelvin temperature can also help guide you in determining which fixture is right for each room.

Whether you need an ambient source of light or one for highly-focused task lighting, keep in mind the following Kelvin ranges:

• Less than 2000K: gives off a dim glow of light, similar to what you might find from candlelight; best for low-light areas where ambient illumination is welcomed
• 2000K-3000K: gives off a soft white glow, often yellow in appearance; best for living rooms, dining rooms, bedrooms and outdoor spaces
• 3100K-4500K: gives off a bright amount of white light; best for kitchens, offices, work spaces and vanities where task lighting is needed
• 4600K-6500K: gives off a bright amount of blue-white light, similar to that of daylight; best for display areas and work environments where very bright illumination is needed
• 6500K and up: gives off a bright bluish hue of light, often found in commercial locations; best for bright task lighting

My question is very similar with similar findings that contradict each othe. IT is confusing. My husband and I are opting for 4000K of each of two Robern AiO med cabs for our master bathrooom. I Ike SIDLER LED collection, too and this is what I found from the SIDLER website that may help you: https://www.sidler-international.com/news/get-illuminated/.

'SIDLER’s LED lit mirror cabinet offers extraordinary illumination, which is custom designed for SIDLER® . It is completely seamless and offers an energy saving alternative to other light sources. Not properly executed LED illumination can be harmful to the retina. SIDLER® is aware of this and puts an extra effort into its design to deliver a secure light source.

Its ability to be dimmable offers a custom controlled intensity level for any time and mood of the day.

All fluorescent lit mirrored bathroom cabinets have a cool white radiation of 4000 Kelvin. This is a neutral color temperature which is ideal for make-up application, as warmer lights tend to cause the over application of make up as it is further away from the natural daylight color temperature.'

For $2K the medicine cabinet would have to brush my teeth too. No matter the quality of light IMO that is not worth the price.

Hi Kim, I'm getting ready to make the same decision. Which one did you end up getting and do you like it?
