I disagree. Everyone knows that this lantern is a heap of poo.

David; I don't know that; indeed, I don't know anything about this lantern; I've never used one, and I'm not sure if I've ever even seen one. Could you please be more precise as to what you don't like about it.

They were basicly a Xenon conversion Lamphouse from a Arc, loads of Odeon's Cinemas had them as well the Plaza Cinema in the West End, London had some up to closure.

David: are you expressing your views as a Projectionist or a Cinema Service Engineer?.

Perhaps we could have your views on the Peerless Xenon Lamphouse conversions [Eek!]

David,

clearly you have some problem with me. As I don't know you or have ever meet you I'll reserve my opinon of you until I have a basis for one. Your ignorance will not cloud that opinion when I form one.

All I have done is to express an opinion on the topic and don't feel I've earned the ignorance of your comments and have certainly not been offensive.

I at least can base my opion of this lamphouse on it's istallation, use and repair.

The evaluation of any peice of equipment is not only based on its technical excellenace but on price and overall ease and cost of ownership. The 'Best' is not always the best for every situation.

Ben, I think you may have a different lamp house in mind. The 4000 is a purpose built xenon with fixed metal irror and offset extract duct on top. Bright blue removable top cover. Quite a slim compact body similar to one of the strong supalumex lamphouses I think.

Most of the horizontal lamphouses in the zenieth line give very good light but they are fussy on alignment and on cooling
the only ones I have had blister the reflector was incorrect alignment and lamp focus

Gordon the thing I like about this lamphouse is that the press studs give easy quick access and the whole top comes off which makes for very easy maintenance.

Unfortunatly many people overlook cleaning the intake fan and it becomes clogged with dirt quite quickly. When that happens the lamphouse can easily overheat and damage the mirror. This is the case with many lamphouses today that are very compact and is not a design fault as such. Hook up a good extract and this lamphouse will provide years of good service.

A few more ideas I thought of, but nothing big.....

The V8 has both a fire-safety "drop" shutter and a zipper-style changeover shutter (in addition to the regular spinning shutter.) The fire-safety was used also as the changover on earlier V8 models. I've seen where one of the two rivets holding the round disk to the bracket sheared, and the disk would hang down in the light beam, partially blocking it. (This is still a problem today with V5's.)

The zipper-style uses a flexible cable to push-pull the zipper open/close. The cable gets loose at either end, and doesn't travel the entire intended distance, again partially blocking the light. I notice that V8 zippers really wack hard when opening or closing and tend to get bent, loosen, etc; I never knew if that was how they were designed, or if it was the result of US/Italy voltage differences.

With xenon bulbs (Osrams) I found a few where the ferrules that clamp the metal bulb ends were loose, allowing the metals ends to slide, throwing off the bulb-to-reflector focal point. So if the bulb is just placed in without adjusting the Z axis, the focus was wrong.

I just send Brad a ZX4000 manual I found. Probably too old to really help anyone, but I guess you never know....

Ben,

Sounds like you're talking about the huge things, basically rectangular in shape, but with rounded corners, and with a smaller section at the back; the Odeon Leicester Square had them when they had the Vic Xs, and I think many other Odeons had them on Vic 8s, but I don't think those are the ones that Ken was talking about.

He had the same type of lamphouse installed on a V5 with 2.5K bulb and no problems. I don't agree the statement that its a "pooh" lamphouse. The light does not match the Kinoton though but the newer lamphouse of Cinemeccanica are really advanced.

Ben silly billy

The seaside air must be getting to you. The Plaza lamphouses were
1a 2a - Xenex 1s however stripped out and with Bernard Bentley conversions in them
1b 2b (on the DP70s) - great big old Cinemecannica carbon boxes with again Bernard Bently conversions in them

These REALLY could be described as poo or any other form of excrement.. but hey, what do I know ?

Dearest BennyBoBo

You sought my opinion on the Peerless Magnarc Xenon conversion aka the McCannLightbox. There are two things you can do with Peerless conversions. The first is to convert them to a drinks cabinet - they look very good with the correct wall paper or do as I often do.

This is a Peerless that I stripped out of the ABC Nottingham when it closed.

Quote Kendall again;

"David,

Well Kendrick. Cast your mind back. We all remember the old Odeon Disney/St.Martin's Lane aka Lumiere do we not Le Ken Rouge? I seem to remember your own ignorance clouding your judgement there!

Good Morning from Cambridge

David

David you seem to have aproblem with what was a simple request. You know my name please use it or don't continue.

As for the past I can't recall you at all and if you can't contain your ignorance whilst on this site then I don't care to.

I really don't think it's worth continueing this rather pathetic saga.

Regards

Peter: good to see you are back on this site and yes indeed those Zeniths were a Bentley Conversion and it was late when I posted about the 450, rather than about the 4000!

I know that this might sound dumb but I did have an experience with the V8 and found that the dowser can get somewhat lazy and will hang down a little bit so you have to adjust the pull up solinoid by adjusting it to get rid of the pull up slack.The electric dowser is very close to the light beam anyway as it is and is caused from wear on the linkage.Hopes this helps.Don't give up.
