I have only a small collection of lights, but I just tested my Thrunite TN12 2014, Olight S1, Fenix E12 and Zebralight SC5w for a few minutes each and I'm fine.
I'm guessing maybe its the way the PWM is on this light that affects me? As soon as I try again, my eyes just get fatigued quickly and I got headachy again..
Haha..oh well... Its only me though.. Otherwise I love the tint on the Jaxman!
Yep, its probably the PWM. None of your other lights have any PWM(the SC5w has a bit of a pulsed current too though but, maybe not as bad). PWM/pulsed is basically like staring a very fast strobe light the whole time you use it. Its a poor way to regulate a flashlight and causes discomfort to many users including myself.
