I have no agenda here, I am not posting all over the forum about the evils of bulbs. I have never been happy with the brightness of my JVCX500 on my 1.0 gain screen, even a fresh bulb is dull for me. I have posted on this thread where I talked about it and how I am totally happy with everything but the brightness. At 1500 hours it is just too dim for me, it is that simple. I hate that I have to justify my personal feelings on my Projector, very odd.

Seems like it's the case for a lot. I'm just happy that the picture looks great from 1.4 screen widths away

That's a good screen I hear. I love high gain screens. Allows for more brightness and more CR. Benefits all around

Even regular HD content? This post makes sense for HDR if your using Gamma D or a crappy custom gamma curve, but I’m at 3500 hours on my lamp and it looks fine, no brightness complaints in HD or HDR converted to SDR2020, I only wish 3D was brighter, but who doesn’t?

A lot of people replace their bulbs after 1000-1500 hours. Nothing new here. Its just the newer JVCs are more stable and can run longer. I never get there, but I usually sell them before the 1000 mark. But if you want to replace them every 1500, should not be a problem. You are the one buying them.

in any case thats not extreme thats VERY extreme at 9000 hours a year and a conservative 3000 hours a lamp thats watching over 24 hours a day 365 days a year ! even if took half the 3000 hours estimate if blowing through lamps running them on high that watching 12 hours a day ? every day 365 days a week ? who would do that unless you are in the very very very extreme category ?

also I am not sure about calibration and how rock solid laser is for 25000 hours ? I remember chadb disproving that claim saying laser isnt quite as solid as some claim and also does droop



1000 hours over years is not extreme, thats 3000 in 3 years or a lamp every 3 years whats that $500 cost ? is that much of a premium ? i wouldnt think so ? to put in perspective like the person I was originally responding to I have dual displays and run telly for most things like every day tv and such which would be too horrid in PQ to be enlarging to a larger screen in anycase. though would watch some sport concerts and bigger screen events, still only manage 1-2 at best 3 movies a week on the projector and in 3 years have just only got to 1000 hours ... and my lamp is in great nick right now there is no ways id consider replacement in any ways.



exactly ive seen plenty with this experience and mine follows this as well. I dont eve run high lamp in my case, but I do think this series of jvc lamps have been great

I was saying I got 1000 a year on my LED projector. I use my JVCs for movies and HDR material. My second projector, which is always a DLP, gets the TV shows, kids stuff, and pc things. Right now, I'm using a Digital Projection M-Vision projector because I love their built quality and lenses.

I hate to say it, but there is definitely something wrong there. You either have a football field screen size or giant windows or something. Do you notice a significant improvement with a fresh lamp and are you happy with it? 1500 hours is nothing and I’d gladly buy those used lamps from you if they are genuine JVC.

I have a full velvet pit with a 115in 1gain screen, I have had this PJ since early 2014. Actually, I was one of the first to get the X500 and even early on I complained about brightness, just not a terribly bright PJ when calibrated in low lamp and high lamp is not enough of an increase to put up with the noise. But none of that really matters because I am simply expressing how I feel about my projector that I have had for several years now. I personally like to change the lamp at 1500 hours because it has clearly dimmed, I used to change it 1000 but managed to push it to 1500. If I shrink the image a good bit I could push it to 2000 but I rather not. I can't imagine I am even getting 700 lumens once calibrated, personally, I would like to have a few thousand.

I’m curious about a full rundown of your settings but don’t care enough to ask. I still think something is wrong though and that’s coming from me, I got temporarily banned for complaining about JVC’s dark “HDR” (and I even provided photo proof).

My offer for your 1000-1500 hour genuine JVC lamps stand. Feel free to hit me up if/when you have some.

he has an X500, pre-2015 model. They aren't as bright as the RS400+ models. Our low lamp is like this model's high lamp

hi cardowski, clearly some quirks of your own setup that need to do what you do or is it personal preference. will leave to you, it is purely your choice as said above you are paying for bulbs. but as i explained its a tough call to justify a laser just on lamp replacement as can see many have now posted the good output and lamp life we are getting by the now well superseded jvc...mine is same vintage as zombies above been 3 model of projector released since ! am sure in a few years time when lasers drop about half what cheapest ones are be much more a justifiable argument for many. thats not to say many haven't gone for lasers now or want to go for one am sure I'll be running laser something some day too. or will it just be a big OLED panel or something who knows....

My mistake. JVC model numbers are so confusing. I thought the X500 & RS400 were identical.


...do they use the same lamp?

I am going down 15in in screen size to get the lumens I crave, I like a very bright image. In fact, when I went from my BenQw7000 I was disappointed that the JVC was a duller image, though contrast was so much better I could live with it. I am sure 700 lumens is plenty for a lot of people and I have lived with it because everything else about the projector is so good. But I am super excited to be getting a lumens jump, I have never been able to crank the iris down I am guessing I will be able to with the new screen. It seems crazy to replace the bulb that much and I guess it is, but it was easy for me to get 300(sometimes less when I got Ebay bulbs)3 times a year, not so easy to buy a new PJ as I built a new theater room, subs and started a new business at home.

Recently I found official bare bulbs for 80 Canadian and with the 2.4 screen I imagine it just got a whole lot cheaper as I expect a bulb will last a lot longer now.

negative on the lamp, it was the NSH 230W which is the same lamp that's in my RS46/X35 from that same time period as the X500/700/900.

I fired it up the other night, it's been many years. It's really a considerable brightness difference vs the RS600. I have only 200 hours on the RS46 lamp and even in high doesn't look quite as bright as the RS600 in low lamp

Looks like I a getting under 600. lol The thing is, everything else is excellent. Very uniform color and sharp from corner to corner, convergence was almost perfect only a slight shift in blue. This PJ with 1500 calibrated lumens would be good for life, well maybe 2000.....

sounds like you have a few things there to counter, which is great to hear ! if can do post a link to source of the 80 canadian official bare bulbs am sure many would be quite keen on those

Oh yes, I certainly noticed a brightness difference going from my RS46 to the RS400 (I also noticed a brighter black level...).

yep I went from x35 to x7000 and definitely noticed the good step jump up while i was still running the x35 on low lamp when sold it after some 3 or so years ownership... the x7000 I was very glad had the dual iris so could clamp right down

Going from a unity gain (or probably less than 1.0 in reality) to a 2.4 is going to be a drastic shift. You'll like it. I went from a .8 woven to a 1.3MP and it wasn't even close. SOOO much more brightness. Had me for the first time ever closing down the iris on my 540.

New, tracked a 100" screen down in Canada. Last one they had.

Listening with Focal Elex headphones, Topping DSD Dac, SENCUN-audio tube preamp with tone control and Little Dot hybrid tube amp with GE tubes.

This is not necessarily a bulb vs. LED/Laser issue.

Modern JVC easily do 1200 lumens calibrated in low lamp and 1600 calibrated in high lamp or even more.

Even after about 2500 hours or so when they drop like 30% that's still about 900 and 1100 lumens.

Old JVC models are just dim, that's just how they were back then.


Just look at the difference in lumens between the old X500:

And something from last year like the X590:
https://www.projectorreviews.com/jvc...r-performance/

You are looking at like 1200 vs 1900 lumens. That's a 58% increase.

Even when the X590R bulb is at the end of its life at like 3000-4000 hours, it will still be brighter than the X500 bulb brand new.

The RS600 was the first JVC projector that was bright enough for my tastes. Brighter in low lamp than the RS4910 I demo'd in my theater was in high lamp. And as bright as my SIM Lumis Host 3 chip DLP for all practical purposes ( not sure how SIM ever measured 3000 lumens from a Lumis ). Brightness made a quantum leap in the 2015 / 2016 JVC's.

Nope - you're totally sane. I wrote down all my measurements over the years too. Nothing dimmer than my Optoma H79 at the end. Something like 300 lumens and 6 foot lamberts - makes your projector seem like a blow torch !

Amazon is practically giving away the 4K remaster of Alien (1979).

https://www.amazon.com/Alien-40th-An...dp/B07P83ZXX4/

This is confirmed a new 4K scan + color grading from https://www.company3.com who have done IT, The Martian, John Wick and many others.



The film they used on this movie is much cleaner than the high grain material that was used for Aliens (1986) so this should look amazing.. looking forward to seeing it again
