MUM14 PHOTONIS 4G white phosphor

Photonis 4G tubes are milspec. In the old days those tubes were called "Photonis Intens". Photonis Echo & Echo+ tubes are fallout tubes of the 4G & 4G+ production and don't meet the milspec requirements

The NVG housing I'm using is an american made MUM/Mini-14.

The specs of my new Photonis 4G tube:

SNR: 31.72
Res: 70 lp/mm
EBI: 0.15
Gain: 9333 lx
