LED lighting panels in our office is so bad it looks as if there is a constant haze or fog in the office.

A number of people in the office were complaining of visual fatigue and a hazing effecting especially after working 3+ hours, additionally multiple people had noted that colours seemed diluted or ‘dulled’.

The light spectrum seems to be missing parts of the visible light spectrum, to test this I acquired and installed high CRI lights and the area in inch I installed them lead to people satin to that they felt less sleep, more alert and more comfortable - of course these are all subjective results.

Subjective TLDR; LED lighting isn’t inherently bad IMO, but bad LED lighting is bad.

Some of the issues (including the visual hazing) could be exacerbated by poor indoor air quality.
Glad to know it can be solved by installing a light.
It sounds like your LED lighting might have a poor colour rendering index? It's a measure of how accurately colours can be perceived under particular light. The best — well, the reference — light source is the sun.

(I only know about this concept from Technology Connections's videos on high-pressure sodium lights.)

Yes it does, I ordered 4x high CRI LED bulbs from https://www.yujiintl.com/high-cri-led-lighting.html, I placed them around my teams working pod in cheap $10 desk lamps and they work a treat, very noticeable difference in our pod / cubical to the rest of the office.
