Fire & Ice Fixtures Together

This is a good question, and the ETC LED team has explored it a little bit.  Right now there are no plans to combine an Ice cell and a Fire cell within a single 21" fixture, and I can give you the two things we're thinking about: 

1) Color mixing becomes challenging between cells spaced side-by-side like that.  It makes it kind of tough to get completely uniform color on a flat surface like a cyc.  Putting a 1-cell (11") Fire above a 1-cell Ice in a double yoke works better as far as color mixing goes.

2) This would make the overall performance fairly similar to a 21" Vivid fixture.  If you look at the combined output of an Ice fixture and a Fire fixture, the color gamut covers the same range as Vivid.  The primary difference is that Vivid is more brightness-balanced for colors in-between Fire and Ice, like amber, gold, yellow, green, etc.  Of course, this may not be beneficial if your application requires only light in the red and blue ranges.

I don't intend to imply that our minds are permanently set against this.  If enough people ask for it, it is certainly within our ability to produce a fixture like this.  However, I think a better solution is a double yoke with 11" Fire and Ice in it--and that's available now.

I figured it wouldn't color mix as well.  I was thinking solely of a top/front/back light solution that gives the dimension of separate cool and warm tones with the added strength (especially with the cool tones) of the fire and ice fixtures.  I'm guessing either the spacing is probably too short to add that effect anyway.  I was just money and rigging space by have a single fixture.  Thanks for the feedback.

I like the way you described the "dimension of separate warm and cool colors."  That is what the Fire and Ice concept is all about.  Consider the solution Rob mentions of a "double-yoke" that we offer. Here is a photo.

You have given us some valuable input--please keep doing so.  I will mention this in our next meetings.  Thanks!

I was wondering if anyone has explored the idea of a "fixture" library  that is a Fire&Ice unit combined into one channel.  Letting the console make the best color using all of the led's across both units?  Or should I just look at a Vivid-R instead?

Kevin,

That is an interesting idea. As it so happens, Fire and Ice use the same footprint as a Vivid-R with respect to control channel assignments. You could patch both fixtures as a single Vivid-R on your console and address both units to the same starting address. You would get the benefit of added emitters in the respective areas of Fire and Ice and save on your DMX output count.

It all depends on what you look you are wanting to achieve as Fire and Ice are both more targeted towards their respective ranges versus the Vivid-R which has been designed to give you a more balanced mix across the entire spectrum.
