s4 led series 3 expanded mode red

we had a demo of the daylight HDR and lustr x8 s4s today and was super impressed with them (both were brighter across the board than our current 750w s4s) !

but when running in expanded or RGB mode when we had just the red channel at full they were just outputting the deep red LEDs and not red unless we wheeled in some green which meant 'full' red was super dim compared to 'full' blue and green which both mixed in some other channels. this was verified by having one unit in direct with just deep red up and the other in expanded with just red up. am I missing something here like a colour calibration setting in the menu anywhere ?

as a receiving music venue we'd ideally want to run them in expanded mode for our facelight so LDs can easily clone over from generics then just set the colour temp they want without having to mix colours channel by channel (especially with the wide range of desks that come through and how some desks handle colour mixing anything more than standard rgbaw)

    I would suggest using them in HSIC Mode (current Firmware v.1.3.0 on fixture is needed). Here you have full color control, and the Color Temperature channel. Most consoles can patch and control HSI+C fixtures. (Hue-Saturation-Intensity+ColorTemp)

    hsic would be great if we could control what desks/lds come through but the trouble is most LDs are very used to rgb or cry mixing and trying to get them to use and understand hsi mixing would be a nightmare. and we've already made the mistake of using less common modes on other fixtures that not all desks have by default where we had to spend far too much time handholding touring ops who barely know their desk to make a fixture profile

    also fades between colours look horrible as every desk I've used (etc may do it differently I'm not sure ?) just fades the hue channel so you just get a horrible rainbow fade

    What consoles are being used in your facility - most should have "decent" color tools for HSI Mode-Fixtures?
    Which console do you use for your own shows?

    Yes - when using a simple mode - like RGB - you lose some of the maximum control possibilities of the fixture.

    If you have ETC DMX Gateways, you can easily set the modes on all fixtures at once with the Concert Software, so that for your shows set to and use HSI-C and then when touring shows come, set it to RGB Mode. This works fine via RDM through ETC DMX Gateways.

    we use avo in house which handles hsi pretty well allowing you to just use rgb/cmy faders still but it still does horrible rainbow fades. and in terms of visiting desks 90% of the time it’s ma2/3 or chamsys but we do still see the odd hog, jands vista, onyx and even compulite once or twice!

    i just don’t understand why red in rgb mode only used the deep red chip but blue and green mix colours

    annoyingly we don’t have etc gateways and even now a good 3/4 of shows just run straight over 5 pin and even if we did have etc gateways we’d be having to change modes when swapping between the house desk for supports and the main ld’s desk which is just asking for trouble!

    Hello,

    Here is a screen grab from EOS showing the RGB color space (the triangle) on top of the gamut of the Series 3 (the polygon).

     

    The red color point is defined by the ESTA standard and is not representative of a Red LED color point.  So when only the R in the RGB color space is used, it is actually asking for a color that that fixture can’t produce.  Deep Red is the closest it can get, which is why only that emitter is used.

    To get Red to turn on, some green needs to be added to pull the requested color point towards the Red emitter.  

     

     I hope this is helpful
