<div>@Ash Sharma , have to agree 100% on this one. According to this post (below) he has 8500 hours on the Epson LS10000, with little light loss, it was up for sale and sold almost immediately. Even at high laser the average user will never see 8500 hours, based on 1200 hours per year, over double the typical useage for most, this works out to 17 years. Factoring in technology advances , the vast majority of projectors are outdated in 5 years, have little appeal/value of any sort outside 6-7 years. Even if the lamp is 90%, technology advances would render the device nearly useless. On the one hand marketing is encouraging the latest advancements to be utmost and necessary for the ultimate experience, then on the other end trying to justify having a product 10 years out, those two realities could not be further apart .
I'm with @mani
on this one. The Ultimate cinematic experience involves the largest screen, turn it on high for all HDR and 3D reduce brightness for the little SDR most will watch . The biggest and brightest image is the goal not longevity. 3-5 years is tops any average enthusiast will be able to hang on if he wants to stay remotely current, all laser projectors running on high will still be near original brightest 8 years out, even based on above average usage . For the few that live in front of a projector and for commercial venues, Laser is an absolute must to keep costs in line. When a laser projector dims by 50% it's worthless to anyone.
The flagship VW1100 worth $30K back in 2011 can be picked up for under $ 5K. That supposed $10K ARC-F lens has little value apparently, and realize it is actually 4K, all others 1080. In 2015, 4 years ago
a Sim2 Lumus 3D was selling for $30,000 , even if it was new in the box today, a 1080 3chip DLP has no value of a relevance today .
I'd say run your laser projector at maximum power enjoy the biggest
t image it can produce . If you want to save money, don't throttle the projector, get a projetor that is much cheaper for a given screen size and run it where it performs best. A great advantage of the Sony Laser line is they produce best performance at maximum laser settings, smart engineering if you ask me.
Now ,if Sony had not addressed the degradation issue long ago, or if there were any indications it even still exists, it would be prudent to throttle back, since this is not the case, there is no need to hold back .
Personally ,I wouldn't buy a sports car and then run it like an econobox to save gas , I'd just buy the econobox in the first place , after all, unless you are unleashing the capabilities, it's simply a waste on many levels .
I'm selling my Epson LS10000 projector and Stewart ST130 screen so I can upgrade to a lower gain AT screen and PJ with more brightness. The laser light engine on the LS10000 has 8500 hours on it (99% of time in mid-power mode), but is still very close to its original brightness, and still has a long way to go on its advertised 20,000+ hours of laser lifetime. Everything is in perfect working order, and I have not had a lick of trouble.
