A true strobe will be shorter duration and weaker in output per each flash. Be careful, a lot of regular flash units have been misnamed as strobes when they were not stroboscopic.

What do you consider a regular flash?
#5 GE flash bulb. Hot when you take it out. Had the flash paired with a Speed Graphic and Roliflex.

I seem to remember you had to be very careful where you put them when you took them out.

Your so right RG. They were hot hot for a minute or so. I am really dating myself huh. lol

You haven't mentioned flash powder, so you can't be that old

OK - found this on the internet (so it must be true)....
"Strobes. Speedlights—also known as hot shoe flashes—are external flash units that produce a faster flash than a standard camera flash and are often used in conjunction with photography umbrellas and softboxes".

What do they mean by faster flash? And what are standard camera flash?

Chris calm down. We’re just talking here. Having a little fun reminiscing.

I agree! A little fun after the OP has gotten a reasonable answr is one thing. Taking over a thread and ignoring the OP is rude. A new user would probably just leave UHH. IMHO

Is a strobe flash faster than a regular flash?
This might be worth a look.

It's a matter of nomenclature, photo slang, and general usage of words vs scientific language.
A general-purpose electronic flash unit or system is a so-called Speedlights, "strobe", or monolight, powere pack wired to the lamp head system ARE simply ELECTRONIC FLASH, Photographers call these "strobes, studio strobes, etc, because these all operate on similar electronic principles but most general purpose flash gear is no REALLY STROBOSCIPIC light sources. Actual STROBES not only provide flashes of light of very short duration but are also capable of rapidly repeating bursts that can be adjusted to fire various frequencies. The reuse in musical performances and stage shows for various animated effects is used scientifically to analyze notions, and photographically for special effects. You might see stroboscopic emergency lights atop police cars and other emergency vehicles or used on highway signage to warn of road hazards and dangerous conditions. Photograhers, including myself, still call much of our flash gear "strobes".
The term "speedlight" was once another generic term for electronic flash because of its very short flash duration that could freeze motion whe the fals was the primary light source. Early modes operated on an extremely high voltage and relatively low capacitance due to the use of oil-filled capacitors which stored less energy and discharged faster. Fast durations of 1/100,000sec. or shorter was not uncommon. The advent of more efficient electrolytic capacitors, lower voltages, and high capacitance enabled ample output and longer but still motion-freezing properties. In the early days, the faster shorter flash duration enabled extreme motion capture such as speeding bullets in flight. Some of the high-powered units that consist of power packs and wired lamp heads, in the 2400 watt/second range may have a duration as "slow" as 1/300 sec.
Nowadays, the "SPEEDLIGHT" is usually a smaller flash unit that is mounted on the cameras' "hot shoe". Someof some camer manufacturers have branded some of their flas unit models as "Speedlights" Some Speedlights and similar models will have extremely short flas duration weh set a low powere either manually or through a TTL exposure control system.
Flaslamps or flash bulbs are different species of flash. They are 1-shot disposable lamps that come in differet outputs. There were at one time various modes with longer and shorter flash durations based on the time that it took the zirconium foil or wire and/or gas in the lamp to remain burning. There wew long, short, and medium peak lamps to accompany differet shutter synchronization requirements for more to less ligh output, special delays for focal-plane shutters, and gas-filled models that kind of mimicked electronic flash duration but were also 1-shot disposables. Most of the specialized flash lamps are long out of manufacture and have become a niche market item.
All ofhte above is very basic and in many instances, "old school" theory inthat many of today's flash units and systems have far more sophisticated circuitry and automation. There is HHS that enables synchronization at higher than recommended normal shutter speeds and all kinds of exposure control devices. Nonetheless, at the heart tof every unt is some stepped-up high voltage, stored in capacitors, and discharged in a pulse, into the flas tube on firing. The energy ionizes the xenon gas in the tube thereby causing the flash.
