I don't know why any shutter glass projector that uses either an IR or RF emitter would require proprietary glasses. An LCD or reflective LCD shutter glass projector, in the lmited cases where the three overlapping beams of polarized light emitted from the projector are lined up in the same direction (as they are in the JVCs but not the Sony's) there is merit in selecting glasses where the fixed polarizers in a pair of glasses are aligned in the same direction as the light emitted from the projector. The benefit of same, increased brightness, however would depend on how high the polarization extinction ratio of the screen is, the higher the better. But even then proprietary glasses wouldn't be required. Of course maybe I don't get something? But to me I prefer RF glasses, and see no proproblem or difficulty in hooking up any projector with an electrical emitter port regardless of the port type (whether normaly intended for an IR emitter or a RF emitte)r, to an RF emitter such as an Optoma or Monster.
As to bulb life, in high mode (the other mode regardless of what its called vs the low lamp or eco mode regardless of what its called) 2000 hours is the normally listed lamp life reflecting someone's judgement as to lamp brightness deterioration. Many run their lamps longer not knowing how much they have dimmed because their eyes have adjusted. Once a new bulb is installed, the universal comment is Wow, I didn't realize how much my machine had dimmed.
People say, I run for so many hopurs and I am so happy, so why don't you. In reality, in high mode, one would benefit noticeably replacing the lamp before 2000 hours (perhaps around 1200 to 1500 hours) but this is subjective. And you don't have to replace, its just an optimazation of brightness thing.
All things being equal, the higher the wattage bulb, the more heat it will generate and the less life it might have, subject to how well it is cooled by the projector. But there are reasons why we don't see higher wattage bulbs than the various bulbs that HT projectors in the say under $10K class use. They just can't handle more heat.
Ah. Its only a moron like me giving you bulb advice. Thje specs for MY projector say I will get 3000 hours on average on high and yours say only 2000 hours. They are both probably bull because the only think that counts is how bright you want it to be from initial turn on (0 hrs) at the time (x hours) you are watching. Certainly not the projector manufacturer's judgement for you. I have know people to run for 5000 hours, dim but they don't notice or care. Me. Every bulb projector at about 1800 hours but I have so many projectors normally, I never reach that hour point. Most projectors are demoes and I only have them for a few months at best. And yes, I have had projectors (No, I am not talking a JVC here), where I needed to replace the bulb every 500 hours. The problem there was a bad bulb design that was fixed in the next generation of that manufacturer's projector. Bulb was relatively cheap anyway.
Some people believe every spec they read. It just isn't so. Its not lying, its just using unrealistic conditions for measurement. Brightness at the highest possible color temperature, bulb life at what percentage of original bulb brightness. Give me brightnes at d65 please and bulb life to half brightness and thank you for being more realistic this year though it might cost you some sales.
The marketing game is about about brighter and higher on off and how a company measures those numbers is not in the specs. You gotta remember that. Bulb life is less of a marketing factor, but is still important to more than a few and once again how the life spec is measured is usually not specified.
Now if you want to discuss what I think is better, the Panny or the Benq W7000, you will have to call, given that I have not yet viewed a W7000 and I have viewed the Panny. You can read the Panny thread.
Hope this help sort things out a bit for you.
