Do a search on you tube under profilux and GHL you will find some there, also i posted some threads earlier.
I would suggest teo spots for the size of your tank

basically the same as the sticks.

I think this is the video you posted before.
I noticed that when the blue lights come on (31 seconds), its not a smooth transition, its a sudden pop, and then it slowly gets a little brighter. I thought they could do 0-100% dimming, so there should be no 'pop' ever?
Is that a limitation of the ballasts, or what? Are the LEDs like that also?
I want to use the LED simu stick for my home-made backlight, shown here:
I'd like the light to SLOWLY and SMOOTHLY fade on, starting at 8am and taking until ~2pm or so to reach full brigtness, with no pop or anything.
In other words, I dont ever want to be able to notice that it just started its 'dim up'.
Same for nighttime. I want it to start dimming maybe around 6pm, and not fully go off until 1-2am.
Is that possible?
Right now the backlight is using luxeon K2 LEDs and I've started preliminary work to make my own PWM/microprocessor based dimmer for them. I know that I can make it perfectly smooth but at this point if the profilux can do the same thing much easier then it will save me a big headache.

The Blue moon light will start at around 15% intensity this was covered recently.
This is due to the fact that the moon is NEVER invisible, the moon will always produce some light.
If you want to stop the sudden on, then program the blue to be at 20% during the day, this is dim enough not to effect other lighting.
The video would also been produced using simulation sliders, so manually dimmed and brightened, not giving the actual true phasing.
Its all to do with the loonar cycle.

hmm thats too bad.
Well my backdrop is NOT for simulating the moon. Its for simulating the average illumination of the ocean itself. Its the exact opposite of a moonlight, I want it dark at night and bright at day with a nice smooth fade to on and off.
is this the same for the sunrise? I definitely wouldn't want the red spotlights to start at 15% and the sunset to turn off at 15%

The red spots fade very nicely

so for the blue being 15%, is this a technical hardware limitation we are talking about? or just an arbitrary number in the software?
for the simu-spot, your website says "Colour - red, blue/white"
does it mean it also has white LEDs? are those 0-100?

I don't understand this discussion but I feel there are some misunderstandings.
Clarification:
- in the simu are 3 groups of LEDs: white + blue = channel 1, red = channel 2
- the 2 channels can be dimmed independently
- the white + blue are one channel, means: they are dimmed simultaneously. The proportion of white + blue can be programmed -> the light color for moon can be adjusted between light blue and deep blue
- the white LEDs are also used for flashes
- the dimming range of the hardware is 2% ...100% for both channels, not taking any special user settings in account

thanks for clarifying.
2% doesnt sound bad at all.
had no idea that you could control the color balance of the blue/white, thats neat!
it will make sense to you once I get my system together. I will try and get a 24 hour timelapse video.
In a nutshell, the backlight and moonlights are two separate things to me. thats why I'm thinking of using a simu stick for the backlight, and a spot for sunrise and lunar. the backlight would be purely ocean color simulation.
