I hadn't noticed any reviews of the 14s JRH had on sale, so real quick...

Ordered 11/26, shipped 11/29.
No spot report but I can't make out any blemishes.
Photonis spec sheet doesn't seem to include a photocathode sensitivity value?
Resolution: 67
EBI: 0.15
SNR: 31.13
Halo: 0.77

Paired against my L3 WP filmless, I have to be in a very low light to see a performance difference (L3 wins), and the Echo seems to do better in mixed light which is perfect for my application (LEO).  Also, I see no fixed-pattern noise with the Echo, which is kind of irritating in the L3.

Came with standard milspec type accessories/paperwork, and seems to be a pro quality build.  I called in the purchase and the interaction was very professional and informative.  Very happy with it so far.

As in the photocathode response?  It's hard to say.  In mixed light urban areas, it seems more like a difference in contrast.  Areas around houses or lit buildings will be more detailed in the Echo, whereas in the L3 they'll be more flooded by the light.  In darker areas with no lighting, the L3 will definitely see into the shadows more.  I'm not really sure how to quantify it.  If you've seen the UNV L3 vs Intens videos, I found them to be a fair representation, considering degradation of image capture/upload to youtube as well as the assumed higher specs of the non-Echo tubes.

THANK YOU for your purchase and of course Thank you for the kind words.

It got CRAZY BUSY starting on the 19th and ramped up more around and after Black Friday, hence the 2 day ship time. My apologies for the short wait.

Glad you are happy with your unit! For the price the Photonis ECHO tubes are generally a steal given the clear quality of the units.

Thank you once again for your business and the kind words!

I would barely call that a wait.  Great experience all around, and I'm already putting the 14 to work. Thank you as well!

From what I've seen online Photonis tubes run low compared to competitors.  Someone had a comparison chart up that showed the Intens tube at 1000 uA/lm@2856 compared to what like the 2k range for everyone else.  I'm not very knowledgeable on this, so don't know if that translates directly into any of the differences in performance, or there is something else going on entirely driving the Photonis line.  There is not even a photocathode sensitivity spec on the sheet.  Whatever it is, the Echo holds its own.  I wouldn't hesitate to buy another... in fact if I can source a pitbull that's what's going inside.

Yes, I think the differences shown in the video are accurate to the Echo tube.  I'm sure a full 4G Intens that made the cut looks better in person, but the final product video looks representative of the one Echo I have.  I actually feel like the L3 was represented less accurately there due to the limitations of capturing NV images.  When you're at 72 res and pushing 40 SNR I dont think you can ever do the real picture justice. But then again I have a L3 and do not have a 4G Intens (though I may have to get one after running an Echo).

Bottom line, I think its a great tube for the price, and with the 10 year warranty JRH is offering, hard to beat.  I won't be giving up my L3, and am about to try my luck at obtaining a "super" spec tube, but for my most dominant application (mixed lighting surveillance and ops that involve frequent outdoor/indoor or NV/white light transitions), I think this will be my go to unit... until I can afford a 4G.

Damn you!!

Extended holiday sale :)

The HP+ Pinnacle uses a green ITT/Harris tube.

Feel free to email, call or PM with any questions.

Have to double check Monday, but I believe right up to Christmas.

Look forward to helping you.
