I use Nitecore Flashlights from 2017 on the firing range (field) and for my EDC gear and i can say the build quality is superb for sure! Not one time has any of my Nitecore flashlights, let me down!
Also i read about TUP Accidentally power ON problems,you should have read the manual where there is a Lock 1 and Lock 2 function to prevent the flashlight to be accidentally turn on !
One last thing is that i have seen some Nitecore CRI flashlights (they can simulate the neutral white colour), check out the LA10CRI , LA30(own this one) and LR10 .
I also have used the headlamp NU32 that has two auxiliary LEDs with high CRI =90 (colour rendering capability ) with output at 35 lumens (not a lot but i can do the job).
So i guess you have some options there,, on their really big range of products!
I hope i helped you a little bit with my personal experience!
