Yeah I was hoping the picture brightness would stay the same for longer than 10,000 hours with the minimum eco so I guess it might not be a good option for long term usage.
Still I hope that with the "high altitude" settings the fans last longer than 10,000 hours.
I wouldn't worry about the fans at all. They look like easily replaceable inexpensive fans, three of them. However, you could always extend the warranty if you didn't get an extra year via cc — I think I'll be more than ready for an upgrade within three years
I've heard different things about the long term brightness. Some of the hybrid projectors (laser + LED) had some issues maintaining brightness however, I think a lot of that had to do with the lasers. I've also heard that LED projectors will maintain near full brightness till nearly the end of their bulb life Others say it may decrease as much as 40% but that decrease is much more gradual and weighted toward the end of life. All in all my understanding is it will be a very gradual reduction weighted heavily on the last 25% of life.
As far as the 10K hrs for minimum eco, that's just a guess. If we went off normal projectors we would probably estimate around 20K hours.
The BenQ W1070
Normal Mode: 3500 hrs
ECO Mode: 5000 hrs
Smart Eco Mode: 6000 hrs (TBD)
Notice the "TBD"
— in other words the new "smart eco mode" is an unknow — just a side track. OH, and we should always remember most companies don't warranty their bulbs past 90 days or 500 hours, whichever comes first. The LEDs in this thing gets the full warranty, afaik.
That give ~58% lamp life in the brightest mode. That equates to 17400 hours for this projector.
Now, a lot of this discussion assumes that LG is saying the 30K hours is "end of life" vs "reduced to 70% capacity" — the latter is how they rate LED light bulbs (e.g. L70, L50), afaik.
Wouldn't clear documentation be great?
— LG's spec sheet for this projector shows 500 lumen. . . so, who knows n:rolleyes:
I'm betting the 30K is end of life with a minimum of 15K hours regardless of mode.
Now the warranty does NOT mention hours of use or light engine life at all. . . so, don't know how they would handle someone asking for repair because it's become too dim.
Are you using it as a monitor or something that will have it on all day long every day?
