I am looking for information on the glass reflector used in this large capacity lamphouse.
Can anyone identify the manufacurer, source, or any information needed to source this?

Have you tried Strong? ![[Big Grin]](biggrin.gif)
Or Ballenswine (Ballentyne) as they are currently known as?
But be ready to either pay big bucks, or if you're told who the OEM was, be told you can't buy it direct. ![[thumbsdown]](graemlins/thumbsdown.gif)
A lot of metal reflectors are made by Optiform, you might Google them and give them a shout.
The current sync motors on Simplex are made by Leeson, but Leeson won't sell them direct. (And I found out from Leeson that the stock number on the motor doesn't even cross reference to Ballentyne, it is another manufacturer altogether and it was originally spec'd for the oil pump of a deep-fat fryer. ![[Eek!]](eek.gif)

When I contacted them, they had no knowlege of it, or a part number. The only mirrior I can think of that is close is the glass 15" mirror Kinoton uses, but I am unable to get the F1 & F2 of either glass mirror.
Sooooo................,
I have posted here to see if any of you knowlegable folks have run accross this.

I'm not too surprised that they didn't know..seems to be common with them anymore...
I have thought of another possible maker..Precision Optics...and it is possible that Optiform may have already made a metal reflector for your lamp.
Try to PM Mark G at CLACO, he seems to know where to find almost anything...he may even have one laying around....
Hope this helps...
Can you get one of those Kinoton mirrors easily enough, maybe "on loan"? If so, I'd go ahead and try it to see if it works.

Is it possibly retrofitted with a Technalight kit?

Ballanswine.. hadn't heard that one. I always thought Wrong International was pretty fitting.
Anyway we definately don't have anything like that at CLACO. If it were Christie we'd definately have it laying around though. I do however reccomend the Technalite conversion kit. With the insideous price increases at Ballanswine these days the TL conversion kit might actually cost you less... it will definately give you a ton more light! There is a 6 screen D.I. here in SLC that has them on all 6 screens and they have better images than many indoor theaters have.
Where is Heir Guttag... he may know bout that Glass Reflector...

Standard Strong is, of course, metal (probably Optiform) The only glass reflectors I know of are Technilite, Big Sky and Kinoton. They may be the same or nearly so. Louis

Nein...do not distrupt the purity of das German reflektor with your silly American lampenhouse.
The Strong reflector the for X-60 that was glass was part number 4271 (Spec 271) and was used up through the X60-C incranation of the lamphouse (and I think the igniter was 220V too). Starting with the X60D, Highlight...etc it was was a potted metal reflector. I believe by the time the Ultra-80 came along that they went to the current flanged metal reflector that can be retrofitted to most any of the prior models listed with a suitable kit.
I was unaware of anyone making a drop-in replacement for the Strong metal reflector. The Technolite solution is more than just the reflector but an entire lighting retrofit as well.
I believe Kinoton used to sell the guts of their lamphouse for retrofit into one of their older lamphouses. One could certainly put that into another housing. As for just the reflector, it probably would not require the highest degree of mechanical aptitude to kludge a reflector into a different lamphouse. As for the working distance...use the numbers that original manufacturer (of the reflector) used in their lamphouse...the working distance is the working distance.

I went to the technalight website, but it just seems a media dazzle display.
In my years at BIG SKY engineering the glass reflector lamphouses, I found that the Kinoton mirrorhad almost identical specs to the Strong/Christie/Neumade/Bigsky
large mirror, which are all pretty much the same optically anyway. The Ernemann mirror isamid-point between the small and large mirrors, but had great optical characteristics for large-screen and long throw applications.
Does anyone here have some hard data and a picture for this application using the Technalight system?

Dan,
I would highly reccomend that you call and talk to Robert at Technilite and he can fill you in on it in more detail, he is the designer of the system. Many, many of his kits have been installed... quite a few in Imax theaters 35/70mm projectors. and no, its not the Kinoton mirror. You could also speak to Bob Destolphi at Ultra Flat. He could in a several hour long conversation tell you all about it and how well it works.

Balzar used to make the Kinoton and Ernamann reflectors
Meopta also makes excellent reflectors
Posted by Steve Guttag (Member # 268) on 09-12-2008, 08:09 PM:
Kinoton offers two types of glass reflectors currently...Balzers and what they refer to as "OEM". The OEM is substantially less expensive.

Weule reflectors of Germany is another source. A foriegn manufacturer has had good results using the 365mm Chinese glass dichoric reflector in Ultra-80 situations.

UPDATE on an old post:
Seeing 19fL on a 35ft matte white screen with a 106 ft throw emitting from a Highlight having a Technalight, 7.5inch reflector and an OSRAM 3k HS bulb at 90amps through an XL is pretty amazing to witness in itself.

Hmm..wonder if this retrofit kit can be made for a XENEX 1 lamphouse - instead of going bigger bulb, but go for more of a effective reflective power.
..sadly, digital is going to eliminate all of this fun. - Monte
