Re: How Long Does Your Projector Lamp Last?

You linked to it once already. More is not necessary. I read it and made my comment because it left out the single most important consideration in lamp life, start cycles.

I researched the issue of cool down many times with engineers from the manufacturers of the projectors and the lamps. The ones who know more than just repeating the owner's manual understand that thermal lag and uneven cooling are not a significant issue in most projectors. It certainly is good advice to let it cool properly, but not the only, nor the most important issue.




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

My optoma H31 (which is for sale) has over 7,000 on the original bulb. It was still strong when I replaced the projector. Have fun. Dennis

Re: How Long Does Your Projector Lamp Last?

Bulb life can be dramatically affected by the climate you live in as well. If you live in a location that is very hot and your A/C does not work well or you dont have any that will kill a bulb a lot faster as well. Projector placement is also crucial in that it must be able to breath properly good air flow around it is a must. Remember that heat rises and if your projector is right against the ceiling that can also create problems.

Panny 700: 5.5 years on the original bulb. It's used exclusively for movie watching a couple of times per week and has about 3000 hours on it.

Re: How Long Does Your Projector Lamp Last?

My projector LCD video lamp I think its rated at 2500 hours and I must have used 200 or so over the past few months ON and OFF it hardly gets used as I’m aware cost isn’t cheap and (home cinema is non-profit) other than cinema so use wisely don’t show it off all the time.

Lamps for my LCD are around 250.00 so sometime soon I’d have to get a replacement ready for the change over.

Re: How Long Does Your Projector Lamp Last?

I have a Panasonic PT-AX200 which started the infamous flicker at just 300 hours. I bought it off a solo man company who fought me over replacing it; I went to what we call the "Disputes Tribunal" here in NZ who ruled that he had to pay me out for the price of a new bulb. I have yet to see any actual money however...

Untill I see any money I'll be putting up with the flicker.

Re: How Long Does Your Projector Lamp Last?

Why not just re-lamp it and when he pay's you you will be all set. I don't know if I could put up with my pj flickering all the time.

Aren't these the units that had the sticky iris causing this problem?
