Re: How Long Does Your Projector Lamp Last?

We had a Panasonic here at work eat bulbs like that. It ended up being a bad power board in the Projector itself. Panasonic replaced the bulb, the board, and sent us a second bulb for the first one that blew prematurely.

Wow that is good service from Panasonic. Wish they had service like that here in Oz. Only horror stories of 500hr lamps and of sorry service here with Pana, although thankfully I never had to use them on my ae700 - was at 1200hrs and dim when I sold on that pj - it would never have lasted the 3000-5000hrs marketing spiel due to fading brightness (only had 4fL on a 108" screen on high lamp at last calibration). Sold it with a new lamp from price japan so new owner was very happy.

Cheers

Re: How Long Does Your Projector Lamp Last?

Well, I have an Optoma EP719, and it's been almost 4 years, and the lamp still works. I've just started using it regularly to watch TV on the DirecTV HDDVR last year during the Olympics. Before that it was just to watch movies. I don't know how much longer it will last.

Re: How Long Does Your Projector Lamp Last?

Just FYI. I retired my Optoma H31 proj. for a BenQ W5000. The Optoma has 7,000 on the original bulb and is still going strong! If anyone wants to buy it, I am including a new bulb, but, It will be interesting to see exactly how long the original bulb will go! Dennis

Re: How Long Does Your Projector Lamp Last?

It is great to hear some of these stories. Most of the post you read are about problems, when I got my pj, I was expecting to change out the bulb every year or sooner. My bulb is rated at 4000 hours, so if I get even close to half of that, I will be pumped.

Re: How Long Does Your Projector Lamp Last?

Well I hate to bust up the Optoma love affair, But my HD72 is on it's 3rd bulb and none have gone past 900hrs. The first time I sent it back they said it was the bulb and so I replaced it even though I mentioned that people were having problems with what was thought to be a bad ballast desiegn. They denied it and when the new bulb went out at 870hrs the PJ was out of warranty and Optoma said too bad soo sad. Then said for 350 bucks they could replace the ballast I have a Benq that has 2300hrs on it and is still working fine. Personally I will never buy another Optoma but you may have better luck. I hope you do.

Generally there seems to be quite big differences between individual lamps.

Re: How Long Does Your Projector Lamp Last?

The most important factor is the frequency of starting the lamp. One should avoid shutting down and restarting over brief periods. The start cycle applies very high voltage pulses to start the arc and wears the lamp faster than running it, to a point. The break-even point is probably somewhere between 1-4 hours of use, according to reps from Osram and Philips.




Looking for me, just google my username. I have used the same one for most sites for many years.
