I can say that there is a manufacturer that has said they're working on an
LED color mixing
fresnel.
LDI or next year
USITT release I'd guess. It'll be good. There's probably more than one, but there's one that I know of.
As far as
LED fixtures my go-to right now is the
Martin Rush
Par 2. For less demanding applications the Elation QA fixtures - EPAR QA in particular - are what I've used. I've noticed that the
current crop of hex RGBAW-UV single-chip fixtures are not at all homogenized once they reach destination - splotches and rings of color all over when I shoot them at a wall. In particular I almost always see a cooler outside ring and warmer/redder center. In particular with the Elation SixPar 100 - the 200 is less splotchy, but the SixPar 100 is all over splotchy (at least from the demo I saw). Maybe this is because of how the hex-chip LEDs are situated? I'd much prefer an RGBA
fixture with a nice,
flat field and no splotches to a splotchy RGBAW-UV
fixture. I'm of the opinion that for a
PAR fixture you still need to run the light through a homogenizing column a la
Clay Paky B-Eye or
Martin MAC Aura to get a nice, even output. Yeah, it adds 2 inches to the
fixture length, but it's worth it for the truly even field of color
Martin did shoot themselves in the
foot by not offering a color frame for the Rush
Par 2 while at the same time including a non-standard size color frame slot. I'd put R114 or R119 in those to soften the
edge if I could, and I've
gaff taped it on there before. It's just a
bit hard edged for some applications.
