My reaction to high colour temperature LED light would seem mild compared to some. This is how they affect me:
Daytime running lights on new cars – Many new versions of these are high intensity, high colour temperature, LED and aimed into the eyes of oncoming motorists. I find these unpleasant and distracting, and worst seeing them in close proximity when walking. I have had migraine aura when driving which I am inclined to attribute to these lights. I now wear orange safety glasses to drive, which effectively reduce the colour temp, but I haven’t found anything equivalent that is visually acceptable (i.e. doesn’t make you look a fool) to wear in the street. Not looking at oncoming traffic is a solution, but I do not consider this safe.
Also I find the break lights on many new vehicles too bright and those migrating lights which run back and fore sideways within the units on slow-moving plant are annoying and mesmeric.
LED street lights – I avoid going down streets which have these if at all possible. They can sometimes give me a headache even after short distances. The advice not to look at them is not valid because if you are driving or walking uphill this is unavoidable. I think the problems are caused by the concentration of the light source (causing glare), colour temperature and intensity. I maintain that it should be possible to look at every part of a townscape at night without discomfort.
Security lights of all sorts, domestic or industrial – These are unpleasant to look towards, they give me a headachy feeling and are on a par with the new LED street lights.
LED head torches – I have had migraine aura and mild pain from these, and headaches for a few hours.
Mobile phone torches and mobile phones themselves can be painful for me to look at in the dark due to excessive glare.
