Lamp Lifespan - Where Are You? - Page 3

post #61 of 214
Model: Boxlight SE2HD (Z2)
Expected lifespan: ????? (Sanyo has never said)
real lifespan: Original bulb went to 3900 hours and then I got a replacement because...... well it had 3900 hours on it. Expected a big jump in PQ/brightness. Didnt notice a difference. Current bulb is well over the 4000 hour mark (havent checked recently) and I think I'm finally seeing some dimness. My original bulb is now my "backup" .

panny as100
expected 2000/3000 (normal/eco)
switched to Eco mode somewhere around 20 hours. Currently at 170 hours. I plan to clean filters every 100 hours and limit use to 4 hours at a time (except for really special occasions).

model: Optoma HD70 (ceiling mounted)
expected lifespan: 2000 hour (3000 on economic)
real lifespan: 2200 (currently functioning)

Installed the second week of November 2006. It is my primary TV that is on just about all the time! Do the math...about 14 hours per day since November 2006!!!!

model: Infocus X1 (ceiling mounted)
expected lifespan: 4000 hour
real lifespan: 4662 hours (currently functioning)

HD still looks incredible and I'm hoping this bulb lasts long enough until I can get a 1080p projector for under $2000. I wonder when the RS1 will hit that price?

I am still running 2 PT-L500U projectors, one at 1,250 and one at 1,000 hours, each with original bulb. In dark rooms, I am still delighted with the performance.

Bought less than a year ago. Probably around 1000 hrs. Died lst night without warning. It was sypposed to show a yellow warning sign, no? It just blew out. Ping...

Model: Sony HS10
Expected lifespan: 3000hrs
Real lifespan: Original bulb was at around 3000 hours and it seemed dimmer than at first. Expected a big jump in PQ/brightness and it was true with the replacement. Current bulb is nearly 2500hrs and I think I'm finally seeing some dimness, will replace around the 3000hrs mark again. My original bulb is now my "backup", and will have the 2nd as that as well.

NEC LT 150 bought 2001
speced lamp-life: 1000h

reseted the lamp counter 3 times: 3200 hours and counting.
color spectrum might have lost a little red and it is a little dimmer than at the 1000h mark - but nothing dramatic. I will use it till it breaks and then buy a new projector...

Looking at the new models, sometimes i hope it would break sooner rather than later....

Epson TW700

Original Lamp @ 204 hrs. 95% on low-lamp mode

I'll run this mainly in low-lamp mode so I expect to hopefully get the 3000+ hrs out of the bulb, but have a replacement for when it goes.
I've been putting about 6-10 hours a day since setting this baby up about a month ago in my new home theater. At this rate it will only last me another year and a half or so.

Epson 400
Expected Life:1700 hours hi-power mode
3000 hours low-power mode

Presently 486 hours since Christmas '06. Going strong. I really expect the lower 1700 hour number since I use it in the highest settings most often. We watch a lot of sports and xbox 360 gaming that require a bright picture.

Hard to watch a movie in the lower settings once you get used to the bright image. So it's hi power non stop at my house!

I believe turning the bulb on (firing the bulb) is what degrades the life the most as well as firing the lamp while the bulb is still hot from previouly being on....That why those who tend to turn it on once a day and leave it on will most likely have a much longer lamp life than those who watch for an hr or two at a time then turn it off thinking thier saving the lamplife only to turn it back on 2 hrs later....its been said that just firing the lamp takes about 2hrs off the lamp life. I also find it funny how many watch what they consider a dim subpare image because they are so afraid that the bulb will die sooner in bright mode...1,000 hrs will cost you like an average of $100 people insnt it worth a better image on the other 2 or 3 thousand hrs?

Interesting but for me running in "high" mode results in more annoying fan noise (Infocus 4805)

EDIT: I have less than 30 hours and still going! Reminds me of people who say they have 10,000 miles on their car and haven't had any issues yet...I'd hope not.

ya I've heard that before....but I listen to the movie and can't hear the fan noise in either mode...plus my saltwater reef tank in the next room would drown it out if the computer fan in that room didn't .......dolby sound was designed to be played at a certian level for the right effect and to hear everything and its too loud for many (thats why some don't like it). But I just can't remember watching any movie with the volume low enough to be bothersed by it (or the fish tank)
I aslo heard the 4805 sounds more like a turbine than a projector fan....My hd70 is way quieter than my x1 in either mode..

just hit 1000 hours on my XGA Hitachi-based PJ. I've had it for 3.5 years so that comes out to 5.5 hours per week. I usually only turn it on for game watching parties and once a week just to see a nice picture.

Just got the new Epson 1080p pj last night, seems nice so far.

34 hours on an IN72 of expected 3000. First 20 hours were at high-power to get bulb to settle. Since then, all low-power.

Only power it up once or twice each weekend for a good 5-7 hours each time. No use during week (if I do, very rare). Averaging 30 hours a month.

That number will skyrocket when the new Grand Theft Auto IV comes out

1900 hrs on a 4 year old Sharp 10K. The bulb is rated for 2000 hours and it just started to warn me I'm getting close. While I know it must haved dimmed the image and brightness appear as good as when it was new. I do have a SilverStar screen which might be helping with the brightness.
post #77 of 214
1900 hours on my 11 month old Sanyo Z4 in eco mode. I'm not sure about how long it should last.

I have a spare lamp that was part of Sanyo's rebate program. I should be set for another year or 2. By then I'll be ready to upgrade to 1080p and the prices should be good.

It looks like 600 hrs on a DT-500 lamp for me..
It just crapped out, I wasn't in the room............

1279 hrs on my Sharp XR10-X, at about 2 years in economy mode. Looks as good as the day I bought it (better actually, after calibration).
post #80 of 214
I'm at just over a 1000 hours on a Sanyo Z4 that I've owned since Jan 2006.

I'm thinking about buying a replacement bulb and keeping the original as a spare. Can anyone suggest a good place to buy a replacement that will ship to Canada?

Thanks.

Hey guys,


I have around 2400 hours on my 05 AE900 panny and I just ordered a new bulb, mainly because, the menu was flashing at me and I was hoping for a brighter picture.

Reading these posts makes me think that putting in a brand new bulb will not make much of a difference. Is this the experience most people have had when replacing their lamps?

Also can I save my old lamp as a back-up or is unusable after I take it out?

Also, how the heck do I clean the color wheel and will that void my warranty??

Thanks

About 435 hours on my 4805.

Yes, the bulb will still work once you've taken it out, unless of course you do something to damage it. Just be careful and you'll be fine.

Here is a link for the 4805 specific thread on color wheel cleaning but it might it work well for you too. http://archive2.avsforum.com/avs-vb/...d.php?t=581503
post #84 of 214
Thanks mym, I'll try the color wheel thing before I change my lamp to see if it really makes a difference in picture. Hopefully I can hold out changing my lamp for another 1000 hours or so!

I just realized my pj was an LCD...doh.

i have panasonic pt-ax 100u with approx. 1300 hrs. of use in non-economic mode. life expectancy is 2000/3000 hrs. and i have had color degradation since around the 1100 hr. mark. i put that 1300 hrs. of use on it since Jan., believe it or not. i have a roommate that watches it quite often as well who is willing to split the cost of a new bulb. i was wondering if the reason i already have degradation is due to the fact of the amount of use in such a short period of time ?

I would think if you have kept it cool and clean, you should look to Panasonic for a warrany repair. I do believe long hours of usage are problematic for these LCD projectors as is frequently switching on and off. Regularly clean the filter and keep it cool is about all you can do to prolong life expectancy. Your projector is new and not much history is available and your total hours of usage is more than most. Running it 12 hours a day is quite a load.

let me make sure about something. i am new to the whole projector thing. when i said color degradation i was referring to a pinkish haze on the left side and a bluish haze on the right side. i think i may be wrong about the color degradation. does the haze just mean that my bulb is going out or is that actual color degradation ? the more i thought about it i began thinking that actual color degradation is the color of the entire picture fading. please fill me in and correct me if i am wrong.

thanks
sonny
