Looking for a flash for an unattended system.
Need field of view like 16m wide at distance of 15 to 20 meters away.
Film speed would be ASA400 equivalent.
Any expert can help to recommend?
Thanks

Are you trying to light up a football field? ;-)

Seriously - you're looking for something really big and powerful here. The issue will be not the 16 m: you could use multiple flashes.

Problem #1 - is the distance. But can be done with something very strong and powerful. Like 1600W or 3000W strobe head. But this is big equipment. Top of the line
Problem #2 - 3 flashes per second. You will be struggling to find something in that category. Normally it takes about 1-2 seconds to recharge a flash, or to be precise to build up the next charge. So firing 3 flashes/second, means a) very little recharge time, and b) ruining your equipment. Strobes shouldn't be fired 'continuously' - it will damage the equipment - and after 10 minutes you will have a big explosion and you're done

I think you are looking into the wrong direction. Consider some big tungsten lights like they use for TV or cinema. They come in large sizes like 2 kW, and put 3-4 of them together and you can do what you want.

Now problem might be - you wanted it for an unattended system - so tungsten/permanent light might not be a good fit. Maybe you explain what you would like to do specifically. Wild life? Or what else? Then we can help you

oops forgot to add, 3 flashes per second per burst, next burst maybe minutes, hours away
not continually... sorry

There may be some specialised (probably very expensive, and hard to find) flash units designed specifically for such usage, but off the bat, I would say something like the metz 60 series flash might fit the bill nicely, are still available (more likely on ebay) and are renowned for their reliability and robustness, besides accuracy both in terms of exposure and color temperatures. Some units in good condition and more than 20 years old perform more predictably than many modern flash units as long as they've not been thrown off the side of a building and the batts have been maintained properly.

Google Metz 60 ct4 to find out more, and Try to PM Larry the Mod; he might still have one in good cond for sale.

CHEERS!

Thanks!
Its rated at GN 195! (35mm) ( feet? )
wow.. didnt know such such powerful flash exits..
think can only remember 42BCT.

Unfortunately too risky to use obsoleted products for this project.
Are there any other with similar power range?

At F2, and ISO 100, distance of 16m,

need GN of 2 x 16 x 3
= 96?

Or only GN of 24 for ISO/ASA 400?

Cheers

Modern digital Metz like the 50MZ and IIRC 70MZ exist, but from my experience with several old and new Metz units, the old ones are sturdier and far more reliable. You'll be very surprised at how many 15-20+ year old units are functioning perfectly fine today.

Yes, it's THAT powerful! Rated at 35mm ASA 100 IIRC.

Other modern alternatives would be the Quantum Q flash which is rated at 150 w/s. Not sure whether your application is sports, scientific or industrial, but there might be other Quantum products that might fufill the requirements.
