Contract over run green phosphor BNVD's. No spec sheets.
1 year warranty.
No gain adjustment, so they run full bright like PVS15s.
No illuminator, you should be using a IR light on your kit anyways.
You want CLEAN tubes that perform well on a budget WITH warranty, THESE are it.
Photos through the tubes aren't the greatest, and are taken in EXTREME low light - so the WORST performance possible, the white dots you see in image 7R are from the LIDAR of an iPhone projecting on the wall. These are GREAT units for anyone wanting binos on a budget, that come with a warranty!
