My guess is something to do with colour temperature, since it's purported to be continuously variable from 3000 - 9000 Kelvin. Perhaps it is the upper achievable colour temperature for a given beam angle.

At $10K per instrument we won't be picking up any of these for my venue any time soon.

I believe CCT stands for Correlated Color Temperature.

Here's a few informative (yet not 100% relevant) paragraphs taken from this link:
http://www.lrc.rpi.edu/programs/nlpi...rum/claims.asp

"Full-spectrum light sources will not provide better visual performance than other light sources under most circumstances. Visual performance is the speed and accuracy of processing achromatic information (e.g., black print on white paper) by the human visual system. At the relatively high light levels typically found in schools and offices, visual performance is essentially unaffected by the spectral power distribution of the light source, so full-spectrum light sources are, lumen for lumen, no better than any other light source.

Lighting produced by full-spectrum lamps may be, however, perceived as providing brighter architectural spaces than other lamps (Boyce, 2002; Berman, 1990). Three factors may contribute to this effect. First, full-spectrum light sources typically have a high correlated color temperature (CCT) of 5000K - 7500K. Lamps with higher CCT values produce greater brightness perception than lamps with lower CCT of the same luminance. Second, most full-spectrum light sources have high color rendering properties, meaning that surface colors will appear more saturated. Greater saturation will also give the impression of greater brightness (Boyce, 1977). Third, the ultraviolet (UV) radiation produced by some full-spectrum fluorescent lamps has a fluorescing, brightening effect on textiles and paper that have been treated with whitening agents. These combined effects on brightness perception may indeed have positive impact on building occupants, but greater perceived brightness can also be a liability, depending upon the expectations of the space's occupants (Veitch and McColl, 2001). "

Edit: Just noticed that there's a WIKI article on this that you wrote. I'm confused!

Has anybody seen the new Martin MAC 301 LED Wash light? I'm Curious how they compare. Sadly, the Martin looks like they decided to just copy an Elation product.

Nope - it's a different product entirely, that was developed about the same time as the Impression and is actually manufactured by JB lighting.

Just as I predicted (time-wise) after seeing a prototype at last year's LDI, the first VLXs have finally been released into the wild for public consumption. Twenty-four units were on the recently-ended Kylie Minogue tour, equipment provided by Solotech: Onstage/Concerts - Vari-Lite.
