I recently got hfq900 lenses that where made in/before 2001 with silver stickers but the plastic front, they where a whole lot better than my gt17 lenses on a 110 inch screen. I allready had hfq900 lenses before with the gold stickers they indeed had the same optics (sharp uniform across screen) as my latter but for some unexplainable reason the coating was missing on tne front part. I heared that someone else had the same problem. It led to reflections from corner to corner where characters appeared mirrored. Also the black was better on my latter hfq with the silver stickers. It was an impressive experience giving a transparence and contrast to the picture not seen before. I guess hfq900 made before 2001 where before 3m?

Well it sure stinks that changes were made without changing part numbers... not good!

Yes and maybe they did the same with hd10e? I have never seen the later Marquee hd10e but reports are not so positive and since Mike does not use them I wonder if they are the same as the Barco hd10e also named hfq900. Perhaps a 3m change?

I heard that the HFQ is the HD10E lenses that did not pass the quality control so that might be why they perform so different?

What has price to do with it.? The Barco 909/ Cine9 is the most over priced, over speced, troublesome of the top 3 9" crt projectors. So just like the 180Mhz bandwidth, why should anyone believe that barco went thru any trouble for selecting quality lenses, maybe they just picked the big screen lens,the HD10E is as that's was what most of their commercial consumers was using.
Its the lens with the widest range, which is a bad fit for being for a HT screen size, where the GT17 specs and the new HD10L is perfectly centered in the focus range for a 110" screen, And I have seen tests where the GT17 and HD10L has been ranked above the HD10E for HT use.

My thoughts are just as valid as promoting the hfq900 based on rumors.

That is why I have stayed with HD10L.

So how does the 3M 2005 HD10E compares to the HFQ900 or the later HD10L at 72hz 1080p

I only know the gt17 and two types of the hfq900 but I also had the hd144 and hd145 in the past. I have seen enough lenses to know that on my screen 110 inch it does not get better than the hfq900 I have now. And the hd144 where good to on my Runco. Very accurate colours!

Well I would like to believe you but cannot... I have seen them all and have stated my preference so I will keep the HD10L

Why don't you let people be happy with their CRT what ever the model is. You qualification of the 909 is very far off and a lot of people are very happy with it. The Marquee is a nice CRT too. The only point where it is better than the 909 is the video and that does contribute a little to sharpness. All in all there are lots of things that make a CRT good not just the brand. If the owner loves it and does a good setup it will be a picture others enjoy too.

My image not accurate?

Good image! Little yellow to the left in the blue or is it the picture? When you read back you will see that I think it is very well possible that HD10 L newer version is good too. Shall we duscuss something else?

I definitely need to try a few lenses, probably on the one NOS marquee that made it to me intact. I only know that there are shiny HD10Ls, the original ones from the mid 1990s, and then the newer (mine are 2006), with the dull/matte barrels. Where the difference came into play is anyone's guess. I did notice that on at least one HD10L that I have from 2006, the lens stickers still say Delta lenses, so that would be pre-Canadian made as per Tim's notes above. I run a 96" wide screen in the shop, so the defocusing of an 'old' HD10L will be obvious, therefore any change in an HD10L should also be obvious.

When I have time, I'll update, probably in a different/new thread.

Guys

I had requested some empty lens boxes from VDC Florida in the 2008-09 time frame, and they had Elcan labels on them; that is all I am sure of.
