Re: L3 white phosphor
I had the green filter pop off of a W1000, and sent it back.
I told them to leave the green filter off when it was repaired, as I knew that I'd be able see better when adjusting the gain lower simply because I didn't have the dampening effect of a green peice of plastic after the CRT.
However, it's really a matter of person preference in that case.
Generally, you don't want it really bright, and you want your PVS-14, for example, to have just enough gain that you can see and not crush your night vision.
In that case, I find that both the ITT Pinnacle, and green seems to work much better. (At least for me...)
