I had a sp4805 for about 4 years and when I gave it away to a friend the original bulb had a little over 11800 hrs on it . hard shut downs and always ran for long periods of time once it was turned on [7-12 hrs usually]. cleaned filters 1 a month. It was dimmer but still a very good picture. Bought hd 65 ,hope I get close to as many hrs out of it.

Did you mean 11,800 hours? That is averaging a little over 8 hours a day for every single day for the full four years.

Yes 11,800 hrs.Used as everyday tv ,on weekends it was probably on longer and during the week from around 6:00 to 12:00. I thought it was a long time for the bulb but I figured if i got these numbers out of it others did too.Seems like not too many get this many hours out of there bulb's. I'll post again if the person I gave it to calls to find out how to reset again which would be 12000 hrs!

I use my Panny AX100 exactly like Mr Mills, but I've never gotten that far, though, I'm on my second bulb, and still have the first one as a backup. I bought a new bulb, at a pretty good deal wehn heartland had my unit in doing the iris repair.

When I got it back with the new bulb, I put the old one (under 3000 hrs) in the closet as a backup, and put the new one in. If this one dies, I have a backup ready till I can get another new one in the mail.

The current bulb just passed 2700 and still going strong. I figure anything over 3000 is gravy. !2,000 is insanity!!

~4400 on my PT-L300U. Around 2500 hrs I pressed a reset button and the display now shows 1800 hrs. I have a Hi-power screen and am happy with the brightness. If this lamp ever dies I'll upgrade to a new PJ, but I'm not counting on it!

My Sony HS10's bulb refused to light-up at all The light code on the unit indicated the bulb was at the end of its life. I did not see any on-screen messages, but it had a HD signal to it and maybe can't display text in that mode? This is not what other HS10 owners have reported, they say they got on-screen messages, but the bulb continued to light-up. Any idea why mine was different? It is a very early HS10, from the first US run.

So I reset the bulb timer and its working again. So its at a little over the rated lamp time, whatever it was at when it quit working, lets say 3000 hrs. It was in economy mode mostly, and has the high-altitude option turned on; we're about a mile high. And it's like 6-years old. It still looks good but I have a crap plastic screen. Kinda low usage hehe, its obviously not my main tv.

I was worried about continuing to use the bulb out of fear it would explode and destroy the PJ, but was told that's not likely - they usually only blow when their relatively new. Is that true? So I will post when it burns-out or gets dim. I am so happy I didn't just blow the bucks on a new bulb! With my usage I'm hoping to get some more years on it!

The PJ has an on-screen warning about the air filter about half-way through, I used to smoke around it. Replaced it with the spare that came with the PJ. I should get another, I think the warning is pressure or flow based and not controlled by a timer so it really does need to be replaced when it complains. Unlike the bulb, apparently.

Today it won't start again, so resetting lamp timer did not fix it, but trying to turn it on several times sometimes makes it start apparently. Wish I knew if replacing the bulb would work.

My Infocus X1 had about 5,000 hours on the bulb when I replaced it. The bulb still worked but it was really getting dim. Shortly after I installed the replacement bulb the color wheel started sounding like a table saw.

On my Optoma H31 I replaced the first bulb at about 2,000 hours since it was getting somewhat dim. The second bulb has about 1,000 hours on it with no problems. It is only used now for outdoor movies or as a spare projector.

My Infocus 4805 bulb started melting its housing at around 2,000 hours followed by the color wheel quitting. Warrantied the color wheel and installed new bulb. After about 1,000 hours the bulb quit. Installed the old bulb and it caused the color wheel to shatter. Projector then went in the trash.

I'm hoping my Epson projectors are as reliable as the H31 and X1.

projector: benq pb6200

expected lifespan:
2000 hrs in normal mode
3000 hrs in eco mode

lamp#1 little less than 3000 hours, functioning when replaced
lamp#2 little less than 3000 hours, functioning when replaced
lamp#3 3001 hours and currently running

allways running in eco mode.
uses the pj more or less everyday for approx 5 hrs.

for sure the brightness and intensity isn't as it was when the lamp came out of the box.
know i'm planning to run all my lamps to the bitter end.
looking to replacing the pj when all the lamps are out or the pj gives up in an explosion.
wanting the panasonic pt-ae4000. little bit disturb about the panasonic-sweden's pricing. here it's about 4000$........just a little bit over the 2200$ in the us.

hej how.

darn, the first bulb just went only a couple of 100 hrs overtime.
sounded like a small firecracker.

had to clean the projector thoroughly (if you you haven't done this before i can recommend Matthew Lynch's cleaning guide).
no damage to the projector though.

well two to go.
better start saving some dough.....
the price for a pt-ae4000 in sweden has dropped to a just 3888$......

My projector gets so dim even before 2000 hours, I always replace at 2000 hours.

putting in 4th lamp in next 30 days for sure.

AE1000U here.

PS: This will be my first super bowl on an old lamp. But I decided to wait.

Mitsubishi HC5500, 1080p, LCD, PJ, rated at 5000hours in the eco (low) lamp mode (used exclusively). The PJ is 14 months old, and I'm at 2200 hours. The lamp has dimmed by less than 10%, estimated.

This PJ has gotten the most use of any that I've owned. It puts out a gorgeous picture, so it's on for 6-8 hours per night, when it's turned on at all. I average about 50 hours/week, when I'm home.

Projector: Optoma HD72
Purchased: March, 2006 (replaced April, 2006)
Lamp time: 2200+ real hours

The common lamp driver problem just reared its ugly head with my HD72 after almost four years and 2200+ hours. Amazing!

Now in the throes of replacing said lamp driver and the bulb together to see if another year or two can be squeezed outta this unit. After whatever time this buys me, I'll be upgrading to a 1080p projector of a different brand.

I should add that the lamp would come to full brightness almost the moment it was struck when brand new. Now (before the problem) it takes a good two minutes before reaching final brightness after striking. This fact and that I don't want to stress the lamp driver with an old, outta-spec bulb is why I'm replacing both at the same time.

I got 47 hours on the clock out of the Chinese replacement bulb in my old Sony HS-10. Plus a couple hours before I reset the timer. And that was over 5-months, I didn't use it much. I don't think I got 2000 hours out of the original either, but it lasted many years.

The last time it worked, it did exactly the same thing as it did with the original - when first turned on the bulb did not light and the bulb fail light came on. But when it finally shut off, I immediately turned it on again and it lit - for the last time. So I got a good 6 hour session out of it before shutting if off for the last time. Guess I should have left it on.

Infocus X9
Bought last June, watch almost everyday. 2000-4000 hrs rated life (4000 on econo mode). I run custom movie mode which is brighter than econo mode, but much lighter than computer mode although sometimes during day games I will put in computer mode due to high ambient light.

Still on initial bulb at 2135 hours. I will post when it dies (reserve bulb on hold).

I got my HC5500 a few months after you, and I am very pleased. I'm at 2900 in eco mode after about 14 months. Looks like it will be a while before I break out the spare bulb.

I have an HD70 which is about 4 years old. I use it almost exclusively for movies and only have about 1200 hours on the original lamp. I started out on economy lamp mode but recently switched to the higher brightness setting when I increased my screen size. I have been considering upgrading this year, because I am now happy with the rest of the setup and am looking for something with higher contrast and a better ability to fill my new screen. However, given the time of year I am hoping the existing lamp lasts through the summer so I can check out what is new and interesting in the fall or pick up a deal on last years discounted models.

Infocus LP70+, original bulb currently at 3100 hours, still going strong.
Bulb is rated for 4000.
Filters are cleaned about twice a year.

I have it in a hushbox with two helper fans (12 vdc computer case fans).

You might be correct, but the folks with DLP's have to worry about keeping the color wheel spinning the whole time the projector is on. They might get more life out of the bulb, and less out of the projector. And, you have a mini heat source running in the room

Sony AW15. Cooling mode: high.
Around 2200 hours (didn't write it down when I replaced the bulb) and the bulb exploded.
Bought it used though, at around 2190 hours .

Epson TW-700

4258 Hrs and still going strong. I bought a new bulb when the Replace Bulb warning came on. Now I just ignore the warning sign until it automatically shuts off after a few minutes after startup. I run the bulb at Theater Black 1 using a DaLite HiPower screen. Someday I may need to use the new bulb.

Epson 8350
DaLite HiPower (106 in.)
