Of course I didn't need to pay attention to any of that because I was just plugging the thing in and turning it on using the included 44 key remote.
So in this scenario is it possible to integrate with a single zone on a 3100 or 3500 series Grafik Eye, even with the low voltage interface replacing the AC/DC adapter in this scenario? I realize I would have to set it to one color and "forget it", only dimming and turning off/on....but is that even possiblem with a TVI or ELVI with a separate magnetic or electronic transformer purchase? It just doesn't seem feasible. I'll post pics a bit later of the system I have for your further comments.
To dim the LEDs using the electronic transformer supplied with your strips I think you would need the ELVI and you would need to make sure the electronic transformer draws the requisite minimum load (40W AC, iirc). Having never tried it, I couldn't say for sure if it would work (or work well), but the scenario does seem to meet the guidelines furnished by Lutron.
You could try with the RF controller inserted between the power supply and the strip, but I have a suspicion it will create problems if you dim power to the controller. Alternatively, I suggest just powering the terminal on the strip directly from the power supply for the color you want.
I recognized this situation from the beginning (having been big into DIY christmas lighting.. I have nightmares about soldering LEDs and resistors), so my plan is for a plain red strip (i forget how many feet I have.. maybe 90 feet/30 meters?).
If you want to add color changing+dimming I think you would have to move to a larger (wattage-wise) controller that would accept a control input like DMX. Or move to a pixel-based ssyetm with a similar controller. I built a few LED controllers that are powered from old ATX power supplies. Of course.. they work great for computer-orchestrated Christmas lighting, but how do you integrate DMX with a theater.. Maybe a DJ mixer board mounted on the wall next to the entrance?
The RF controllers included in the packages are fine until you need more strip than the controller will power. Mario had an issue with just that in the Cinemar Theater thread.
