So looks like I may actually get to the 2900 hour point and still be able to do 10 ftL or more on low lamp mode throughout the life of the bulb by opening up the iris slightly over time.
I've been very pleased with the stability of light output over time. With the rate we use the projector (a few hours/day) looks like we'll be able to do about 3 years per bulb while staying in the quieter "low lamp" mode - which I'm very happy with! |
Obviously those newer DC lamps and/or the power supply, cooling, etc. are a far superior combination to the older machines. My RS45 was nearing the end of its life at around 1000 hours. I'd opened up the aperture almost all the way, and it was just getting to the point of unacceptable brightness. I'd imagine it only had a couple hundred more hours left.
A $350 lamp every three years just isn't bad at all.
Good to know. Thanks for the updates, Kal!

Hmmm, that is really interesting. I have been going back and forth about buying a new or getting a new bulb and holding on to this one for another year.
Does anyone know where to get an original Philips/Osram bulb inexpensively? The best I think I have found was from one company that sells them for $210 with the whole housing an additional $40 or so? Of course, I am not totally positive that they are OEM bulbs even though they say they are. I did find one place on ebay that looks like it might be OEM, but again not sure.

I'm not sure saving $40 or $50 is worth it, Spanky. Might be a case of "penny-wise, pound-foolish".
A buddy in Chicago called me and asked if I knew where to get parts for his Pioneer RS2 clone. I asked him what happened, and he said he'd just changed the lamp, and when he fired it up, something arced and got so hot it melted the connector where the lamp housing plugs in. I asked where he got the lamp and he said, "from Amazon." I asked how much he paid and he said, "under $50." I asked him how the whole "cheap lamp" thing was working out for him now.
Funny side story. I told him I'd try to give him a hand with finding the part, so I went to log in at Mac's forum to ask about the part or getting the service manual page with the part numbers on it. What? My user id is blocked. Apparently he was so butt-hurt about me signing off on making Hog a mod, he blocked me from his forum. What a baby. Good riddance.
BTW, my buddy got in touch with somebody at JVC and it turns out the lamp connector is part of the optical block, which JVC would gladly sell my buddy for almost two grand. Of course, the projector isn't worth half that - in working condition. He's shopping for a new projector now. Lesson learned on cheap generic lamps.
Cheers,
SC

Cheap generic lamps have their place. In $50 projectors

+1. I will only ever buy from my dealer. I won't even look online at places that say they offer "official" bulbs as that can be a crapshoot too sometimes.
I also won't be running past the recommended 2900 hours even though that's probably fairly safe to do (I'm sure 2900 hours before a bulb blows is pessimistic?).

Agreed. Doesn't make a whole lot of sense to put a $150 lamp in a $50 projector.

Agreed. If you buy from an authorized dealer, you know it's legit, coming from the same supply chain as the projectors. If you buy it from anybody else, it could be counterfeit. Considering the price of the lamps, it would be pretty lucrative business manufacturing knock-off housings and printing up some official-looking boxes. The seller likely wouldn't even know if they were selling knock-offs other than when problems arose. Well, that and the price... If it's too good to be true, it probably is.
I just don't see the sense in spending thousands on a projector to get a superb image and great sound, then trying save a couple hundred bucks every couple of years. It doesn't make sense to me. It's like buying a new 911 or M3 and putting generic brake pads or cheap tires on it or having Grease Monkey change the oil. No thanks.

Good call on not running past the 2900, though I'm not sure I'd even go that far. Is it worth the increased risk of blowing up the lamp to get that last $20 or $30 out of the lamp, loafing along with a CRT-esque 10fL the whole time? Replace it now and get your bright vivid picture back and throw the old one on the shelf to have a cheap backup. That was my thought process, anyway.

I thought CRTs took tubes not lamps. 
I agree with what you guys are saying. I guess I am confused why there isn't anyone selling the bare bulbs for a cheap price. The only sure thing is the dealers from the manufacturers. My issue is everyone knows who makes the bulbs. I can't believe it is that hard to go to Philips and get an OEM bulb.

Luckily most of the lamps I use come from non functional projectors, which come from government surplus - and the government doesn't mess around. A lot of the lamps I pull are genuine lamps that were replaced right before the projector took a crap or barely used. Otherwise I only buy my lamps from one source that I can trust. Anywhere else, I won't buy lamps from period. I can usually get any genuine lamp I need for a projector for less than $40 if I have to buy it, and its usually a bare bulb.
Someone on here once asked me why I didn't sell the lamps I pull - and above I believe is a good reason. Why sell my genuine new/barely used lamps when finding one can be a task, or when you do find one it costs a ridiculous amount (depending on the PJ its going for of course). Anyone like me that has a quantity of genuine lamps like I do usually won't sell them, unless they aren't into projectors like I am.
I do agree with not running your lamp to the max. A possible lamp explosion or possible short could happen and it just isn't worth the risk on such a fine machine

Mac, do you know of a place to buy legitimate Philips/Osram bare bulbs?

I have no idea what "people like you means", but believe me Ron... The feeling is mutual.

An update!
Doing the math since I went digital: Got the JVC RS56 installed in December 2012 and have put almost 5000 hours on it over ~1700 days, so we're averaging just under 3 hours/day.
I'm about 2000 hours into my second bulb now and ended up going to high lamp mode earlier than with the first bulb, mostly because I like getting 14ft/L on the screen. The image is so much more punchy and dynamic. (I know a lots of people who have only run CRT don't see why you'd want something brighter, and until you've done it for a while it's hard to understand but you'll never go back).
So I've been running on high lamp mode now for about 500 hours. Now at the ~2000 hour mark the iris is actually opened up all the way too so not sure where the light output will end up once I hit 2900 hours on this bulb. If it drops too much under 14ft/L I may end up replacing the bulb before the 2900 hour 'warning' mark.
All in all I've been super happy with this thing. Even in high lamp mode the projector completely exposed/open is quieter than my previous hushboxed Barco Cine 8 (which was already one of the quietest CRT projectors out there). The greyscale/colour has also been extremely stable too over the life of the two bulbs so far. I've barely done any tweaking at all.
Obviously JVC has come out with newer models since I bought this RS56 back in late 2012, but I'm still very happy with it and have zero plans on upgrading.

I'm glad to hear it's doing so well for you.

I don't blame you. Most changes have been incremental in nature. The only thing I can think of that has been dramatically improved between then and now is 3D. Unless that's a big priority for someone, 'upgrading' wouldn't make much sense.
(And no telling, with the end of 3D TV manufacturing, how long the studios will even keep releasing discs in 3D.)

I'm hoping people get disillusioned with 3D and want to ditch their otherwise-perfectly-good projector. Cheap. I'm ready to make the switch if I can find a good enough deal. I shoulda jumped on the $800 RS45 (with new bulb) a couple months ago, but with full-house remodel and two boys in college....

Sadly true!!
But for right now the HT is stacked waist-deep & more in boxes from the rest of the house. Right now you can't even get to the seats, and if you could, you couldn't see the bottom half of the screen...

Yup. I have no interest in 3D. I own about a dozen 3D movies and 6-8 pairs of glasses and I just find it kind of "meh". I get it, I just don't care for it. The RS56 unit is a bit dim for 3D but even if it was brighter I wouldn't be interested.

Probably not much longer I would imagine as most of the sales of 3D discs would be to owners of 'regular' TVs which as you mention are no longer made.
