Old theatre lights CAN be useful.

Charc, is the socket in your radial ERSs that you think is a screwbase actually a medium prefocus? If so, you have many lamps from which to choose. Once you post the pictures, I'm sure someone will identify them, then we'll tell you the lamp we used to use, and ship will come up with the preferred modern variety.

I'll go grab some pics before Meeting.

(Meeting? What's meeting you say?! Meeting for Worship. Part of the quaker religion. I go to a friends school. Essentially we nap in silence for 45 minutes. Look it up.)
 
Using Graphic Converter, do a "save as" and select a lower resolution .jpg, thus a smaller file. And/or crop the photo to just the fixture.
 
I feel I must confess to an error, before STEVETERRY catches me. The fixture out of which I made a desk lamp was a 2nd generation S4, as it has the integral safety attachment point. Conveniently, it also has 3 holes in the top of the yoke, to allow for offset hanging (or use two clamps side-by-side, if you're sure you never want to pan the fixture!;)) The "handy handle" on the lamp cap came about with the HPL750, and thus I suppose is the 3rd generation.

Perhaps someone at ETC can fill in the gaps and add dates to these iterations of the Source4™ ERS. I know there also have been several lens tube modifications over the years. The timeline at http://www.etcconnect.com/minisite/sourcefour/history.html is somewhat lacking in the minutiae of details.

Yes I hugged my SourceFour™ today, but the older one that I didn't make into a lamp is now jealous, as it's hanging in the garage next to a Strand-Century LekoLight.

Yes, I realize I need to dust. The garage doubles as a wood shop, and everyone knows carpentry and electrics don't mix.

I just noticed that "safety attachment" point yesterday. At least I assume that's what I found. Are my safeties supposed to be permanently attached to that point?... oops.

Well here are the pics of the Polaris. Is it worth trying to find a lamp for and added a stage pin?

Edit:
Forgot to take pics of the radials, they are in the background of pic 3. Can you see the lamp base type?

This is the unidentifiable PC.
Notes in instrument:
Only distinguishing marking has its own picture.
Note that the gel frame holder seems to have a terrible design.
Note the lamp, which I've never seen before, and there seems to be no reflector.

Certainly. that's a modern high performance Ianiro pole-operated TV fixture that will put out a lot of light and have a nice spot/flood range. It looks like it's in pretty good shape.

I would say it's from one of the smaller manufacturers of the 40's and 50's--perhaps Duwico or Columbia.

Definitely not Kliegl.

BTW, that "bad" gel frame holder was designed for quick gel changes.

There have been many thousands of small improvements done over the 15 year life of S4, and they continue. They are not really collected in one place for dissemination. Good thing, because they are mostly boring manufacturing improvements or optical prescription changes!

Those units are Altman 360's, (not 360Q's). Normally known in the rental business as "incandescents", as opposed to "Axials". I must confess, it seems like "radial" for an ERS is a Control Booth term!

They take a medium prefocus T-12 lamp (probably almost impossible to find these days) or a quartz conversion like the 750W EGG (as in ANSI code, not food type).

They were designed for the C13D filament of the prefocus T-12 lamp, and the EGG is a smaller coiled-coil filament. The LCL is similar, but the filament geometry is wildly different. As such, you won't get a very nice field with it. It was one of the first attempts at a quartz conversion lamp.

Charc-
Here's a link to the .pdf for your Strand/Ianiro/Quartzcolor Polaris. [SIZE=-1]www.strandlight.com/PDF/US-05/Polaris_07April05.pdf Note it could be as young as 12 years old. You'll need the appropriate socket and 1000W lamp. It is a studio fixture, hence the pole-operation, but you don't have to use the pole, and it's impractical over 15' anyway. A very nice light.

As for the PC Spot, also known as a box spot, it's an antique, and not worth refurbishing for stage use. It IS missing its spherical reflector.

Your radials are Altman 360s (not Qs). It IS a medium prefocus socket, and can take either EGE 500W or EGG 750W. Original lamp was a non T/H 750T12/9, ANSI code DNT, but hard to find and more expensive than the EGG. Maybe ship knows of a more modern lamp than the EGG, but I doubt it. Use the lens in the sunlight trick to determine if they are 6x9 or 6x12, clean them up inside and out, spend a good deal of time bench-focusing them, and they will be perfectly usable. This is what everyone used until the axial 360Q came about.

I first heard the term "radial" used by Larry Scheoneman, owner of DesignLab Chicago, in the mid 1980s. Someone here on ControlBooth said their theatre called them "toploaders," which I really like and want to propagate!

I agree that it's not worth refurbishing but it may not be missing it's reflector. I have a few antiques of similar era (Strand Patt 45 etc) that had no reflector at all. The problem was that reflectors were made out of glass at that time and were expensive so the really budget lights didn't have them. The Lamp looks like an old Phillips T1 bayonet base. (UK/Aus) Modern replacement is T24? not sure.

I think the lamp is a G-18 medium screw base, last commonly used in mini scoops called "wizards" around 1980.

I think Larry made it up. Maybe it's a Chicago thing.

In New York, we call them "incandescents".

(For any of you that are lucky enough to own the classic roadhouse crew tee shirt: "We don't care how they do it in New York", sorry. New York is where the thing was invented!)

We talked about the whole reflector/non-reflector thing in the Question of the Day board a while back. Seems the reason was that, besides cost, the screw base lamps of the day were hard to get correctly aligned with both the focal point of a reflector and the focal point of the lens. If you did get it right, it could move easily. Thus, the beam was more even WITHOUT a reflector than with one.

Also, I wouldn't call that a box spot. A box spot is truly a "box", like the Altman #101. Thats just your standard, old-school PC. Looks like someone rewired it. At least you don't have asbestos to worry about. Clean it up and display it in the lobby before the show with a donations bucket beneath it.
 
Re: Multiple replies on radials.

I woulda noted them as 360 Radials, but I coulda sworn I saw a sticker on one that said "Century", or something besides Altman. However, given my track record with the "Strand PC", I could be wrong, remind me to investigate.

As for naming them? My Dept Head has referred to them as chimney lights, as "they can only be placed in that orientation (lamp base pointing up) so the heat can escape".

The ones I have there are in pretty bad shape. We do have about a dozen in service in our other larger venue.

Next order of business:

Anyone ever had to completely disassemble a 6x22 because, for some reason, the template-holder holder was 180º out of alignment? That was not fun, but I got a new understanding of how lights are assembled. I was assuming during reconstruction that ever shutter is supposed to be sandwiched between two of those metal disks. I found two shutters on the same "plane" with two metal disks stacked ontop. Also, for the life of me, I couldn't get those **** shutters out of the fixture without breaking them.

P.S.
What do I do with the relic?

I feel your pain with the 360's. In my rehabbing some 360Q's, I learned alot about their construction. Hands on experience, always the best! Those shutters, yes the only way to remove them it to cut them off or drill out the rivet and pull out the shutter. Only the "modern" 360Q's have provisions for shutter replacement.

As for the relic, like I said, clean it up and hook it up in the lobby before shows with a bucket for donations.

I'm not sure if we are allowed to stoop as "low" as donations... :rolleyes:
 
Well then, use it as a tech table light a a sign of your insane geek-cool-nerd-tech awesomeness.
 
My college T.D. out here in Seattle taught me axials and radials... so it's not just a Chicago thing. I've never heard anyone call them "incandescents" out here. I've heard "Leko" used really generically... even used to describe a Source Four.


Charc, Derek has shown you the way. Take that antique and build yourself an ubergeek lamp from it. Or you can save it as the first part of your personal collection.


So you're at a Quaker school huh? I suppose that explains the extreme concern for your safety. :rolleyes:
