Can someone give me some info on these guys? I've been checking Arri.de and done some comparisons, but all I really get is strength of the light and beam angle, no information really to the "quality or appearance" of the light.

These 12K HMIs with Fresnel lenses have 3542 and 2490 Footcandles at 50 feet, while the Par 12K HMI got 1330 Footcandles using its spotlens.

So what is the deal here? I know how Fresnel focus the beam and makes harder shadows, would be nice with some info as to how the other lenses affect that sort of thing. And I am not just interested in Arri lenses, but any brand and type that might be of interest.
