For those who don't know this lights: It's a 1000W short arc xenon light with 50 million candela reaching miles and miles.
Usually mounted on M60 tanks and other vehcicles, from the Vietnam Era up till unaided night vision equipment became widespread.
What I like best is the extremely narrow beam, being 1 degree up to 7 degree. (Search CPFF for VSS, some beamshots there.)
A bunch of CPF-ers have/had them, so hope they jump in with some info.
I had the luck of stumbling over a VSS-3. Naturally I couldn't resist. Now I've got a bare light unit, without cables or controlbox.Sorry, no beamshots yet.
For Europe I think it's especially a rare find. Don't expect to find me a controlbox here, so placed an ad for that on CPF Marketplace.
Thrilled as I am, I am fully aware it might take a long time to make this work. (After all, what's the use of a having a light that can not be fired up, and it could be a non-runner anyway.)
Hope to get some answers to make this powerlight shine!
Main question: What's inside the control-box?
And thus, is there a work-around using different parts, or can it be duplicated/reverse-engineered?
(Power, wiring and connectors is not the problem. It's the igniting of the lamp I think.)
Other questions:
-Who owns a VSS-3? Is it working?
- Anyone managed to, or heard of powering up a VSS-3 without a controlbox?
- What is the arc-length of the bulb?
- Just-in-case: does anyone know what bulb can be used for replacement?
Thanks to googlebooks I got some manuals, for the VSS-3A: (Housing has rounded corners.)
TM 5855-217-12-1 (1970) Operator manual VSS-3A (NSN 5855-00-177-3529 and NSN 5855-00-405-0404)
Besides that there are some diagrams to be found, from 5 different models (electrical-wise):
TM 11-5855-217-35 Maintenance manual VSS-3 (NSN 5855-00-058-1293)
They are difficult to read and don't know yet how to make up what model mine is.
For the VSS-3: (Housing has partly chamfered corners.)
To some extent the build and operating of the VSS-3 and VSS-3A are much alike I think.
TM 11-5855-217-35 (1971) Maintenance manual VSS 3 (NSN 5855-00-058-1293)
TM 11-5855-217-12 (1970) Operator manual VSS 3 (NSN 5855-00-058-1293)
Especially this Maintenance manual is elaborate about its inner workings. Couldn't find any for the VSS-3A. Does there exist one?
I am looking for one of the following control-boxes:
They should have the following numbers on them:
C-7905B/VSS-3 FSN 5855-00-189-6065 or
C-7905A/VSS-3 FSN 5855-00-177-3525.
Although the label of my light says VSS-3, it is a VSS-3A, this can be concluded from the federal stocknumber.
The controlbox for the VSS-3 (7905 FSN 5855-135-0154) does not work and damages the VSS-3A.
The VSS-3A works and accepts both types of controlboxes designed for the VSS-3A.
( Apparently there where made 5 sub models of the VSS-3A, they al work on any of the two above mentioned controlboxes. ) These lights have a controlbox, and a remote controlbox with fewer controls and without plugs on the front and without the testswitch. I do not need the smaller remote control, it just doubles some switches on the main controlbox.
(I do not plan to buy new connectors, as I don't even know if the lamp nor bulb is working. )
It could look like this:
Type-plate of my light:
Searchlight, Infrared MX-8272B/VSS-3
FSN 5855-189-6066
80063-SC-D-647252
Ser.No. 0186
CONTR 73-C-0147
CEI
MFR 50054
I can not date my light, is it from 1973 ?
So, any information welcomed !
