Flash/Strobe output can surely be ramped up in Watt-Seconds, but there's a reason why lighthouses and airport beacons use Fresnel lenses. The Fresnel lens concentrates the light beam enabling it to extend a greater distance at greater intensity. Alternatively, Parabolic reflectors achieve similar results.

I use Buff E640s and the Buff Beauty Dish is a sort of parabolic reflector.

You are mistaken in thinking that about the beauty dishes, but Paul C. Buff, Inc does make narrow angle reflectors

The company also used to make a true parabolic reflector: the Retro Laser.

What Buff doesn't allow is a Fresnel lens. I would suppose that many would wish it as the Fresnel lens is going to be more compact than a parabolic reflector. Right? I believe so.

there are various Fresnel light modules tha can be used with your Einsteins. My favorite is the K5600 24” Big Eye

Certainly, parabolic reflectors and Fresnel lenses narrow the emitted light, but they should not be confused with doing the same job that snoots and barn doors do.

You are correct and add to that list grid spot modifiers and flags.
