So I recently stepped up to the plate and bought a L3 Unfilmed White Phosphor, Res: 72 lp/mm SNR: 38.6. PC: 2716 Halo 0.8 EBI: 1.5.
This was after I bought a new PVS-14 a month earlier that was a "HP+" thin filmed green Pinnacle model. I was so UN-impressed with the new $3000 unit compared to my 5 year old PVS-14, it actually had less clarity than the old tube, I sold it brand new. I was expecting a huge improvement, but was unimpressed.
After much discussion with industry partners here, I decided to throw down the money for a filmless white phosphor tube PVS-14. I was very impressed. I couldn't believe how much brighter the white was. I don't know if it's just because of the high specs, or because of the color. I have done much comparison between my green and white units. The white definitely sees more with less light. I hardly ever use IR illumination with the white except to find eyes. I like the white better.
