Migraines

We started a private school at our church. They wanted brighter lights to help the kids with vision issues read better. We installed daylight 5000k T8 bulbs in the light fixtures. That started giving the teacher migraines, so we switched back down to 4000k T8s (I think they were Sylvania if that matters). That seemed to work in this case, but I would go with 3500k if they are ok that. Surely they all have that in their homes...

What I've read so far, below 3500 K is better.
 
Warmer will help. Dimmers/lower intensity might also help. I would also see if you can catch a flicker in the bulbs when any of the AC units switch on. Though that would be more of a nuisance than a migraine thing.

Operational Flicker of florescent is an issue. Most of us don't see it but its there or was on older fixtures.

I had a former office manager call me about lighting for people with migraines. She now has them. She knows her office lights need to be changed to LED with lower K.

Wondering if any of you have experience with this and a possible brand suggestion.

Years ago, I had to change a light to a lower K because the worker was susceptible to headaches. I’ve heard also people being susceptible to high frequency ballasts too.
 
So I get them I have medicine for it and I have my house at 2700k bulbs because of this.

You can't avoid having high k light in public places but I like to have homes lower Kelvin to help prevent that being an issue for anyone who goes there with one.
