I haven't seen anything like that, you should ask what the brand is next time your in. The light is going to stay where it is in the third picture more or less. I can't move it any closer (bleaching corals might be an issue). Light is still not in btw , hopefully it shows up soon!
Sorry to intrude on the thread... but I was reading through and saw this. Was it an AZOO palm? I have used them on my nano tanks, and it is a good little filter, and inexpensive.

AZOO also makes a slightly larger model with a built in skimmer, that looks interesting, though I have never used it...
