Name that followspot! (Capitol #1001)

I thought I waited an appropriate length of time!

Interesting that on the data sheet is a 901 followspot.

And here's a 902 in the attached pdf, but they aren't the same!

The clue lies in the family relationship between the Altmans and the manufacturer of the followspot in question, methinks.

Awww jeez, now I have to remember did Charlie work for Capitol or Century, before he founded Altman ?

Capitol.

So it's a Capitol.

Can we skip to the trips down memory lane for a while ?

Kyle, you just dredged up a memory of my having lunch with Ronnie Altman (Charlie's son and heir until he passed away too soon), Charlie and the rental "guy" - Tony Sklarew, at the seafood restaurant behind the factory one day (since removed), as I awaited a rental to be prep'ed. Ronnie was a terrific guy, loved sailing and kept his boat behind the shop on the Hudson. Charlie was a curmudgeon was my impression. Probably just hated young punks like all good curmudgeons.

Funny thing about Altman Rentals back then. You learned not to rent anything in the 4 weeks (2 in the fall, 2 in the spring) when Tony was moving Ronnies boat to/from Florida. Nothing good went out of the Altman rental shop in those weeks that Tony was gone .

Ah, those were fun times

Capitol.

I think there's much more (which I'm just discovering) to the story than we know. It seems Charlie's brother*, Edward, owned Capitol Stage Lighting Company as early as 1937.

Another brother, Arthur, owned Eastern Stage Lighting. All that's missing is the Levy brothers: Joseph, Irving, and Saul. And Larry, Daryl, and Daryl.

So as to not bore the children...

...What does the "the mythical black box" do and, more importantly, why?

*Charles and Edward Altman were not related.

 

[CrazyTechie]

I'm going to guess that the black box is a power converter/ adapter of sorts. Just a Guess.

EDIT: And a guess as to why, the lamp requires a different wattage or voltage than what you can get out of a regular outlet? Just a stab in the dark.

 

[otherwho]

it drops the voltage to 60V using a Three step transformer. <-- the black box thing

The low voltage lamp is brighter that lamp of a higher voltage.
year: before Dec. 1963

 

[derekleffew]

So a 2100W 60V lamp is brighter than a 2100W 120V lamp?
Is a 2100W 60V lamp brighter than a 1050W 120V lamp?

 

[otherwho]

So a 2100W 60V lamp is brighter than a 2100W 120V lamp? Yes because the filament is thicker and can run at a higher temp. this makes the light make more lumen per watt at same lamp life. The light would have about 1-10% more lumens.

Anyone wish to contradict either or both of the two statements?

According to my thirty-year old GE catalog, the 2100T24/8 (60V) has Initial Lumen output of 54,100. Compare/contrast to ANSI codes CYX or EER lamps.

Besides raw lumen output, what other advantages/disadvantages might the 2100T24/8 (60V) have? <Hint: What other fixture(s) used that lamp?>

Yes. But not if it will result in abuse.

Besides raw lumen output,

what other advantages/disadvantages might the 2100T24/8 (60V) have? <Hint: What other fixture(s) used that lamp?>

the 35mm Movie projectors like "Semi-Professional", "Special" by DeVry used 2100T24/8 (60V).
It color temper is lower? There is little on the net on about the bulb. 2100W 60V Base: T-25 Hours: 50 3100K 54,100 lumen filament:C-13D Base: Mogul Bi-post. burn pos: burn within 30 degrees

Might the lamp might be more vibration tolerance than CYX and EER? Both the CYX and EER have higher lamp hours and are a bit brighter. Is the C-13 filament a poorer for a followspot
than C-13D filament? Was the use of CYX lamp copy right by Altman Strand Strong and Capitol not allowed to use it?

Given the a CYX ANSI lamp volt: 120 watt:2000 base: G38 - Mogul Bi-post filament: C13
burn pos: burn within 45 degrees lumens: 59000 color temp: 3200 hours: 250

EER/120V/2000W ANSI volt:120 watt:2000 base:G38 - Mogul Bi-post filament:C13 burn pos:burn within 45 degrees lumens: 58500 color temp:3200k hours: 750

Another, similar unit.


Was Major related to Altman also? I susupect they just bought it from Altman and put their name on it.

 

[mstaylor]

This has turned into a good QOTD. I have been around a long time and I am not familiar with the spot in question. Ihought I was but obviously I was wrong.

I agree-it looks like a private labeling deal.

That's why the old farts are chiming in so vociferously! There is a lot of great history in Derek's innocent original question--stuff that he had no idea he would uncover.

Another question for our young turks: If there was powder in the lamp, what was it for?

ST

 

[venuetech]

as i recall the lamps were burn base down only. with the mogul bi-pin posts were hollow. the powder filled the hollow posts and likely was there to aide in heat distribution

Sorry, no.

ST

 

[zmb]

Was this mysterious powder used as electrical insulation?
Also, is it the same stuff found in the base of MR16 lamp bases?

 

[jstandfast]

Another question for our young turks: If there was powder in the lamp, what was it for?

ST

An abrasive to clean the interior walls of the lamp when they began to cloud with crud
from the filament deteriorating; rather like cleaning a coffee pot with ice and coarse sea salt.
