I have some Chauvet DJ Slimpar Q12's but I gotta say, I'm disappointed in the brightness. They just seem lame. I also seem to have issues with color mixing. If any of you have items from Chauvet, my understanding is that you hit Menu until you see "U" then hit "Enter". This brings up the Red, Green, Blue, Amber with the color values up to full at 255. If I bring the Amber down all the way to 0 and the r,g,b to full (255) I should get white light (which I do). However, when I bring down one of the r,g,b colors (let's say for this example, red) to 80, I see no color change whatsoever (whether while I bring down the red from 255 to 80 or whether I hit 'enter' after I reach 80). Am I missing something?? It's like I'm unable to color mix at all. Trying to determine if I have a problem with the fixtures. In any case, they still don't seem to be that bright and I'm open to suggestions. I love Chauvet's Freedom Par Quad 4 but I expected much more from the Slimpar Q12 in having some great bright colored pars to wash a dance floor.
