Yeah, I wouldn't worry about getting an ND filter, most of us don't use it. BSE53 is our specialist in that area, even Coderguy and me don't have one, but it is nice to know we could get one that worked if we needed one. BSE53 is in Batcave with black everything (walls, ceiling, etc). But the average guy/gal using this PJ is probably in living room , den, bedroom, porch , with regular colored everything. And although the pro8200 is very bright out of the box, it gets tamed as you put some hours on it.
I rather have it this way, than get a PJ that looks GREAT out of the box in brightness and over 2,000 hours or 3,000 hours on bulb is too dim. Coderguy is doing the testing on the Pro8200 at different hours, and he is at 3,000 hour mark, but it would be nice to have tests like this on the other PJ's too (optoma hd20, mits hc4000, etc) so we get real numbers as what we can expect down the line with bulb life as to picture brightness. It could be that the mits hc4000 at 3,000 is 1/2 the brightness of new bulb and so you would need 2x the bulbs as the pro8200, I don't know, but it could be right. So testing in this area would be useful for all these PJ's. Maybe graph or something.
Now, also the testing might have to be done, all in eco mode, because there is difference in what we can expect in lamp hours depending if we use eco mode vs regular mode. 6,000 hours compared to 4,000 hours. Not sure the mits hc4000 would be bright enough in eco mode, but the pro8200 certainly is, so 3,000 hours might be the upper limit for the hc4000 but not with the pro8200. Something to look into, I guess. I am babying my pro8200 in eco mode to get the most hours out of the bulb.
