Well, it all depends on the dimming capability of the lightbar. Some LEDs are assembled with capacitors in them, and when you try to dim them with this type of controller you actually increase the voltage to the LEDs and they quickly fail.
From the description, I'm guessing they can be controlled using 3 LOR channels for a whole lot of colors. What do they cost per unit?
Something like this might make a good Co-Op DIY. It wouldn't be difficult to have something like this made cheaply.

I have a product similar to that, mine is a flexible strip. These use the 5050 SMD RGB LED (same as the LED's in FireFly). According to the link you posted, these LED lights can be controlled with a DMX 512 controller so they are dimmable. Also these are assembled with 12 Volt common positive and are compatible with LOR's CMB 16 D DC controller. I have one and it works fine with my flexible LED strips.
Many of these LED strips can be cut down to individual circuits and with a CMB 16 D controller, you can have five circuits of RGB LED strips. I have tried that and it works. This should help a little.

The light strips in the original post use a common positive, which is also the case for the CMB16D. It should work fine.

You could run a 12 VAC transformer into the input of the left side of a CTB16PC. This would give you half-wave, so it wouldn't be quite as bright, but it would still work.
The CMB16D DC controller is an inexpensive way to control these LED strips if your already using LOR as compared to going to the DMX route. If one were to start by using three channels of this dc controller, more channels of LED strips can easily be added to the unused channels given that they use 12 VDC common positive.
What I meant about five channels of RGB was taking individual RGB LED strips and configuring each one as three LOR channels for a total of 15 LOR channels driving 5 RGB LED strips.
Also the logic side of the CMB16D requires DC current to run it, it runs on 12 volts dc easily and 12VDC power supplies are cheap and easy to get.

This is a little more indepth, but along the same lines

I know that this was some years ago. But this is spring and summer around the corner. And when I was your age, and could not go to work at Micky D's or anywhere else for that matter. I was cutting peoples grass for cash. And at the end of the season, ask your customers to write a little note to the effect of how satisfied they were with your work. It will help you later with some of your first jobs. Show that you have a proven track record for hard ernest work. So, go cut someone's lawn for cash. See if your folks will match what you make cutting grass (someone elses that is).
