I've done the same calcs for my projector and I came up with the 10 ftL range for an 87" wide screen. Not sure where I went wrong. But yes, those lumen ratings are for a 10% window. Unless you're watching Ice Age I think you can come reasonably close to that (for small bright areas) for most movies, certainly for the dark movies CRTers love. But any sunny or otherwise bright scenes will definitely overtax any CRT. That's the nature of the beast. |
True, movies like Ice Age and Happy Feet are the closest to ANSI lumens in a movie. But movies are brighter than you think.
Gladiator is not a bright movie but it has many scenes that hit 50% APL. If you look at a histogram of the first 1000 frames, it hits between 40% and 50%.
All I can say is that my Barco 8" LC machine on a 106" 16:9 1.2 gain screen was delivering less than 8.5 ftL and it was too dim. A Cine 9 at 120" which be just a touch brighter than mine. True, if you don't know what you are missing it is OK, but man once you watch a sufficiently bright image you don't want to go back!
YMMV.
BTW, the Cine 9 gets its 300 ANSI lumen rating in "boost" mode. I don't think most are running "boost" mode in an HT!

Seems like an odd comment given that I know of a large number of CRTs that have been replaced with JVC projectors. In fact, it is probably the most common upgrade from a CRT. IIRC the JVC was the projector the Guy Kuo used almost exclusively to replace CRTs. |
Good to see you back around Dave. I'm glad to see that your argument for digital projectors seems to be more about brightness in this thread. I've read the thread earlier today, and while at the boulevard later, i went into one of the Home Theater stores to see what I've been missing with the new technology, in comparison to the Sony Ruby I saw last year at a friends.
I was amazed that things have not changed much with them... yes, they are brighter than CRT, but how could they be classified as being better??
I've looked at almost everything (or at least the best in the store), to come up with the same impression I got from the Ruby last year. The Ruby was not as bright, but it did share with the recent ones I saw today, in still projecting an artificial looking image. It's amazing to me that there's so much hype from time to time here in a CRT forum about the greatness of todays digitals, when they still make everything projected from them look like either a cartoon or something that was created from graphic engineers.
Now let me say that I'm making my living these days working on digital systems. And I mean the very serious high end commercial units, that has the very expensive light engines and best chips.
Anyway, after getting back, I looked over in the Digital forum ($3000.00 up) at AVS at the screenshots they were praising that came from these same projectors you keep mentioning. In almost all of those shots, I'm seeing the exact same cartoon or plastic look that I saw today... and wh ydo they have such a problem with getting natural colors?
It still amazes me that people are claiming better image quality from the newer digitals:

thanks everyone for such great advice.
after reading everything, i will steer towards a 100" diagonal 1.2 gain screen... i dont want to lose that crt "pop". i guess like everything there is always going to be a tradeoff. i guess i can just sit the audience closer to the screen? what if the wall the screen is on is only slightly larger than the screen, can i trick the eye into thinking it's a massive screen?
lots to think about!

so the day finally came... i just cracked open the crate!! 
barco really went all out with this last design, what an impressive looking machine!
just looked at the sticker on the lenses, theyre hfq900hm's? not sure if these are the standard lenses for this model. the bottom half of the lens is steel while the top is plastic; theyre very heavy lenses! i got the original manuals and remote in mint condition. part of the ceiling bracket is still attatched (the part with rope). the other part didnt come from the ceiling in one piece (damn bolts)  the mounting manual i also received said it's an "800 series" mount. maybe i can source the other half instead of having to custom fabricate it? just a quick look at the outside of the case and its perfect! the gold badge is a nice finish on the black case...
she's sitting in the garage waiting for someone to help me lift her inside tonight for some testing/photos. i found some type of grease where the bottom of the lenses are located. im just waiting to open her up to confirm i dont have a leak of any kind!

i may need some professional callibration however - calibrating my cine 8 is not enjoyable - is anyone in melbourne recomended?
thanks! |
Where abouts in Melbourne are you located Justin ?
I run a 909 (and various NEC's) at home and use a ColorFacts system for calibrating.
Cheers,
Russ

so i cant find my mini usb cable and had to send the pictures i took from phone to phone and lost alot of image detail (auto resized). i'll post some higher resolution images when i find the cable...
i havent turned it on yet. im going to wait the 24 hours. it doesnt look like the set has been opened (it's unmolested)... need to confirm the hour count but it looks like a really great buy! the previous owner (who paid $85k nzd?) replaced it with the latest anthem projector (which makes me the second owner). i dont know anything about these anthem projectors but it must be mighty impressive to replace this thing!
not sure how many volts wall sockets run at in nz... hope i dont fry this thing!? how can i check what it's set at?
thanks for looking!

yeah it does look small hey. them lenses are heavy as. glad they werent on the set when i carried it up a stairway into the house. going to be fun flipping this thing over and hoisting it to the roof... 
at the cost of sounding like a whinger, i didn't get any lens covers. i'll have to fabricate something but keep it covered in the meantime. i bought some bausch and lomb sight savers (little moist pads) to wipe the lenses on my cine 8. i noticed it does a great job but leaves slight smearing once it dries. i went through a few new pads to try get the streaks off but it just shifted around the lens. anyone had a similar experience with these pads? the cine 9 lenses are ok but i'd like to get the finger prints off if i can. should i use these pads on them?

Yeah man That machine is clean. For cleaning the lens do it once and that's it, scrubbing can cause problems. Problems you don't want especially with those rare HFQ's.
http://www.curtpalme.com/Lens_Cleaning.shtm
Also dig around in the advance procedures pages, lots to read and absorb, but it will give you a basic point to formulate what to ask.
Also don't be afraid to ask question everyone here wants to help you get the most out of that beauty, and make sure you don't accidentally cause damage.
Don't rush, take your time just like your doing. If it were a Marquee I would be less cautious because parts cheap and easy to get, with a 909 that's not the case.
Keep posting and you have a great time with that beasty.

Justin, I would NOT go smearing up the lens surface just to get rid of some fingerprints. You're likely to damage the anti-reflective coating, which could have a more significant impact on your image quality than a fingerprint or two. Fingerprints on the *front* of the lens will be totally invisible in the image. Hell, you can stick your whole FINGER in front of the lens and you'll barely notice it.
If you feel an irresistible need to clean the lens, try this: get some good lens cleaner, and some de-ionized water, both in spray bottles. Also get some 100% cotton tissues if you can find them, or maybe a very soft old T-shirt. Spritz lens cleaner on the lens, enough to dissolve/dislodge any dirt or grime. Let the spray and the chemical action of the cleaner do the work. Keep a tissue at the bottom of the lens to soak up any excess. Once you're done with that, spray with de-ionized water to rinse. There's a very good chance it will sluice right off the lens and not even need any wiping, which is optimal. If you think you need to wipe to get rid of water spots, then VERY gently touch it up with the cotton tissue. Avoid wiping the lens face if at all possible.
That should get it plenty clean, as clean as you need, with no risk of damaging the coating.

im really going to sound like an idiot here but, googling "autoranging power voltage" doesn't answer the questions i still have. i read the whole manual twice and it does not say anything other than using a 3 prong power plug (must have grounding pin.) this 3 prong power plug is the same type of plug you use for your pc's power supply, correct? theres also no switches on the back of the set to change the voltage to australias 240v ac wall power supply. is it safe to assume this set will limit whatever voltage comes into the set and uses what it needs? i vaguely remember with my cine 8 curt could change its voltage rating... he changed it to 220v(?) i think and it worked fine.
im basically pissing myself because i don't want to smoke this thing! when i plug it in i want to do two things; make sure everything fires up ok and check the hours on the set! what menu do you go into to find the hours on the set? and can i leave it running with no image for 5 minutes before turning it off? i dont want to turn it on only to find the hours and flick it right off again for the fear i may cause damage by not letting something warm up properly before shutting it off? do i put it in standby before i turn it off or?
i will leave cleaning the lenses for now but i've found another lens has some glue on it or something. that'll need some attention i think? does the glass curved bit from the lens touch the c elements? or just sit really close to them? i dont want to get the c elements dirty because the lenses are?
thanks for the help!

The auto ranging power supply means that the power supply will work within the two voltage limits without any adjustments needed. So just plug in
Otherwise wikipedia says :
New Zealand I 230 V 50 Hz Electricity (Safety) Regulations 2010 state supply voltage is 230 V ±6%

plugged her in. pushed the power button. it went straight into standby. pressed the onboard remote power button and it fired up fine... very quiet machine!! it's too close to the surface im projecting onto to focus, though. adjusting the lenses has no affect. i'll have to carry it out into the loungeroom tomorrow and fire it at a roller blind. damn! dont like carrying this thing

That is a thing of beauty indeed. Heavy mofo though!!
Tip: it's a whole lot lighter if you take the lenses off first...
