I am a HUGE supporter of these lights and I own about 36 of them overall. I have the lights with the rings as well as the regular lights that can be changed into any color of the spectrum.
When I purchased these, I thought I would be able to still use the main light and connect it with "Rhythm" through my cell phone and allow the lights to play along with the music. That is by far, for me, the coolest thing is to have a party and the lights changing colors to the music etc. But when I first saw the rings, PLUS the lights, it was like it could not be better. I'm not sure "why" the manufacturer didin't design the circuit for the main lights to change colors, because, now, its pretty boring in my dance room, where I have 8 of these and 4 large speakers in the ceiling. The only colors are the little ring things, and well, that just isn't enough. I'm going to remove them and replace them with the regular lights that actually change colors to the music and so forth. But, I will have to find a place for these somewhere; maybe in the hall way, I don't know.
SO, BUYER BEWARE ... the MAIN LIGHT DOES NOT CHANGE COLORS. You have to get the regular ones by Lumary, which are awesome also. And, btw, I have ALL of these 36 lights connected through ALEXA. I had to get an extender (and that was a whole other experience, I ended up with one from AT&T that actually works) but now its pretty cool. The only problem is for my BRAIN to remember the name of all of the different light groups. I think I have about 14 of them. I even put the colored ones in the eaves around my house. Awesome at night. Have fun with them!
