Manual flashes with guide number >120

I know the Vivitar 285HV and the Sunpak 383 Super are popular flashes, but what other flashes out there have manual settings, guide numbers of 120 or more and has a low sync voltage? I'm having a hard time finding the specs of anything else or experience on these other flashes.

Your subject 'Manual flash' does not agree with your example flashes (285HV and 383) Both are 'Auto' flashes in terms of exposure control; both are 'non-dedicated' in terms of electronic communication with the body for certain functions (e.g. flash ready light in viewfinder). There are many flashes that meet the description when you leave out the word 'Manual', that are 'Auto' as well has having multiple manual (fixed) output levels.

Metz even adds the ability to have 'dedication' to specific brands and models of cameras, via its modules that make a single flash unit suitable for use with multiple camera brands and models. My Metz 45CL fits onto six different brands and models of cameras that I own, for example, via module changes.

But...
The Sunpak and Vivitar units the OP mentions both have adjustable manual modes in addition to traditional automatic mode. This, and the fact that they have a safe sync voltage, make them the popular choices for low-budget flash units that can be used on or off-camera.

To the OP: I don't have a direct answer for you. But Metz, Sunpak, Quantum and others still sell powerful "potato masher" type flash units. They're going to be quite a bit more expensive than the two you mentioned though.

Look here for some info on the trigger voltage of a lot of old flash units.

Although not stated, my point was that they are not 'only manual mode', nor are they 'only automatic mode'.

That should give an idea of voltage, gn's shouldnt be that hard to find for a given flash
