Thanks, Enrico. You just saved me from taking the time to measure that. It's visibly plenty bright in low lamp and that's how I run it, so I didn't bother. Lol. But does that mean Mark's theory inferred from his experience with the Sonys is now thrown out the window, or should Nigel still test for the difference?
I think for the sake of putting things to rest, @ARROW-AV should test for the difference, and I'm sure he will :) Just the fact that in the past some people measured a difference of 55%, that doesn't mean that Sony is still carrying the same difference down to the new models. To be honest, I don't care what other people measurements are as my 295ES is brighter than I was expecting, to the point that with most HDR movies I run it in low lamp.

Right. That's why I didn't actually measure mine. Low lamp on a 16x9 133 inch/ 2.35:1 125 inch 1.1 gain screen with mine is plenty bright. The 695ES has a 280 watt lamp and the JVC NX9 is only 265 watts; I guess because of the lens/light patch and how power is delivered the JVC is brighter.

Yeah, that’s why I thought it would be bright enough for me in low on a 2.35:1 112 inch 1.0 screen in the shortest throw but it isn’t for HDR, I’m using an HTPC with the newest madVR builds. I’d be fine with about 1000 lumens but not 700.

Your lux reading was 318 in low lamp taken off the front of the lens area?

@ARROW-AV Thank you very much for all your hard work and dedication to this comparison. It will be absolutely enlightening and interesting as can be. You are doing a great service for the community and I thank you. No response needed just wanted to put that out there. Your hard work is invaluable.

I think you should still measure. The 675ES was for sure around 58% of high on low. I don't have 285ES lumen measurements in my spreadsheet so I can't say how that was, therefore, I can't argue against 1350/950.

But it hasn't changed between the 285/295 and 675/695. Otherwise the bulb life estimate would change as well. There just weren't a lot of changes on these projectors anyway. Mostly just same thing with improved HDMI.

Mark, you know as well that advertised lamp life on Sony projectors is just marketing as the lamp after 600 hours drops like a cliff (if the lamp makes it up to 600 hours). I change my projectors lamp right before 600 hours no matter the brightness. The only projectors I let the lamp run more than 1200 hours are the Christies just because each lamp cost more than $600. Also, on the Christies the lamp drops more than 60% after 1500 hours.

My 675ES lamp died *hard* at 880 hours. Everyone told me it was a defect. The JVC lamps, if you run on low, last forever. 2500-3500 hours without that much drop.
Anyways, I have an RS4500 now what do I care :)

Ok I pulled up my spreadsheet on the 675ES. It seems that the difference between low and high can vary with the bulb. Perhaps some bulbs produce less light when driven less and its not purely linear. This would explain some of the variance.

Anyway. All readings taken on Bright TV setting:
Sony 675ES
2/15/2018: 210 Hours Low 1111 Lumens
2/15/2018: 210 Hours High 1816 Lumens 61.2% difference.
5/28/2018: 881 Hours Low 625 Lumens
5/28/2018: 881 Hours High 1025 Lumens 61.0% difference

I just found this on a German Forum. Ekki from Cine 4 Home published this for the N5. I can't find the direct link.

Dear big-picture friends,

Ekki published the first measurements of a N5 last night in his FB group.

I just write them down here:

16000: 1 to 20000: 1 depending on the zoom, Iris open
1450 to 1160 lumens depending on the zoom, iris open

Ansi 190: 1

DCI just under 90% Red is a bit away from the target point.

ADL:

on / off 15000: 1

1% 5900: 1

2% 3700: 1

5% 1800: 1

10% 900: 1

20% 550.1

50% 190: 1

Contrast drop in the ADL probably depends on the total light path. Interplay of Zoom Lensshift etc. similar to the values ​​of the N9

:eek:

I won't get started on talking about washed out faces set against bright backgrounds because I already jumped ship on these new JVCs a while ago.

And keep in mind that even the low to mid-range DLPs can show higher ANSI contrast measurements, closer to the Sony 4k machines. :)

Oh, and P.S., remember that ANSI contrast is irrelevant --unless there's talk that the new JVCs will have a 50% ANSI contrast increase, then it's worth talking about. ;) :p

Hey Ekki @Cine4Home would you mind share more details about these measurements? We really appreciate your input. Thanks!!

You know what is great is that I still have my UHD65. On the 24 10 people from here will be able to see an uncalibrated RS2000 vs DLP. I am sure they will see the same thing that shocked my wife and I. Not even close.

For a few years, 4K wasn't worth talking about... contrast was all that matters... and suddenly now everyone's selling their E-Shift for 'less' contrast.. :D

I have actually seen quite a few of those $1K DLPs and they are pretty stunning for the price... will definitely be awesome to see what you thought of them side by side...

Also, we are just recently learning our eshift unit is a dud, which is coming just a wee bit late in the game, if not too convenient in a conversation of new alternatives.

I would love for AVS to revert to a policy of a little less SALES and a little more SCIENCE.
