Or find a trigger voltage converter for the Vivtar? Might be a cheaper route. I know Wein and Vello make those hot shoe to hot shoe adapter with safe voltage or safe sync features.
The Vivitar 285 - or - Vivitar 283 + VP-1 Varipower module is the right flash for the job. Add a Wein SafeSync HSHSB to bring the 278 volt trigger voltage down to 6.7 volts. (Measured my voltages just now).I'm looking for a very fast flashlight to stop fast action. My flashlights have burning times from 1/800 s to 1/2,000 s, which is too long for what I want to do. I once hadaVivitar capable of 1/25,000 s but it had to high of a trigger voltage so, I got rid of it. Who is aware of a low-cost ultra-fast flashlight on the market right now? preferably up to 1/50,000 s

In my quest to capture amazing high speed photographs I notice that when photographing shooting bullets the bullets were blurred. I found that standard xenon tube, which standard flashes use, is very bright for the energy put into it because of glowing xenon gas. The book Electronic Flash Strobe by Harold Edgerton explains all the calculations, but in practice this means all the flashes from Nikon, Canon and others that use xenon flash tubes have a minimum duration of 1/40,000th of a second. That’s fast enough for most things, but not for a shooting bullet travels around 1000 feet/second. In 1/40,000th of a second that bullet can travel about 1/3rd of an inch leading to blurry photographs of bullets.
To solve this I had to make a faster flash. I’m certainly not the first to do this. I think that was Harold Edgerton. He actually created a company called EG&G to sell a product called the 549 Microflash, but that company has been dissolved and the product discontinued. Sometimes you can still find these flash units on ebay, but the ones I saw were selling for $8K+. There is also a company called Prism Science Works making a modern version of these for researchers, but you’ll need really deep pockets to afford one of those. I saw directions on how to build one in the August 1974 issue of Scientific America and emailed Alan who had already built a few. After this research I realized I could build a sub-microsecond flash for just a few hundred dollars. A sub-microsecond flash means the flash duration is less than 1/1,000,000th of a second or about 25 times faster than a xenon flash.

Or you can use a strobo slave to fire any flash without electrical connection
For example, I use the above setup (Wein SafeSync on hotshoe, to the extension cord on the Vivitar) aimed at a cheap strobe slave to create an optical trigger to fire my Photogenic flash.
The caution is to disable any “red-eye reduction” pre-fire on the camera. And put the flash/slave in a box or something to keep the trigger light off the set.
Metz 54MZ manual indicates short duration of 1/20,000. Its trigger voltage should be safe for most film cameras.
my Vivitar is gone! ditched for a NikonSB-26, which has a very low trigger voltage without extra help. The Vivitar is a current monster; But yes; your proposed setup would certainly work. thanks
over time, any trigger voltage above 5V will damage camera connections.
I tried reading the manual for your flash. It’s certainly a capable unit!
Never heard of it, never seen it. I’m calling fake news that voltage over 5 can damage flash contacts.
This is one of the funniest things I have read on the internet.
Please show one cameras contacts burned by ISO 24v and accompanying spoiled negatives when the contacts failed.

This one is 30 micro second minimum. You might look around on a scientific type site for faster. Pure colors will be faster than white because of turn-off time (phosphor decay). Try some of the specialty rental shops in Burbank for specialty lighting.
Some LEDs will be in the nanosecond region, but the output will not be great. I should think a deep search will turn up a microsecond LED strobe. Won't come cheap.
