Fader times seem to be staggered…

Hi - same behaviour on FLX S24 and FLX. 
 

Generic dimmers lag behind LED as scenes fades in. 
I have programmed a number of scenes, the backlight and window lights are LED battens or LED xbrick type fixtures, the face light and wash light are tungsten fresnels or profiles. 
When a scene is triggered - with fade in, out and colour all the same time, the backlight and windows come in first, followed by the wash and face light. 
it looks ok as it looks like I’m doing it on purpose but it’s not the effect I want.

I’d prefer all the lights to fade in together. 
 

any ideas?

thanks

How big is the lag? Can it be explained by a combination of dimmer curves and heating up (of lamp filaments)

  Check the dimmer levels on the fader screen.

As per @Davidmk's post, this sounds like a classic case of LED dimmer curves vs halogen dimmer curves.

When LED fixtures are at 10-20% intensity, they can often be pretty bright, depending on the make/model. When halogen lamps are plugged into a dimmer set to 10-20% intensity, you often can only see the slightest glow.

Many LED fixtures have a setting on them, allowing you to change the dimmer curve to respond more like generic dimmers. Some fixtures allow you to change this setting remotely from the console.

If you cannot change the dimmer curve of the LED fixtures, you may need to program two separate cues in the console - one to bring on the dimmers, and the second to bring on the LEDs. The second cue could then be configured to run simultaneously with the previous cue, using an "Auto With" trigger. You may then wish to delay the Up time on the LED cue, or tweak its fade time, so that the LEDs and dimmers fade on together.

Hope this helps.
