Optics vs reflectors seem to have come a long way since the fraen lux III combination.
Have a look at this page for some interesting information on Optics:

TIR optics which are in use by SF and the optics used on the Malkoff drop in seem to me to be big improvements.
My E1B has a nice round beam (old optics projected images of square LuxIII emitters somewhat well but the beam was ugly) and is very bright. SF's tir really does a fine job of concentrating all of the emitters energy into the beam. The E1B has virtually no side spill. The Malkoff light has a completely different beam of course.
Anyway this technology is very interesting.
