ASC tube trap full round with dark and light sides - diffusing vs absorbing

I've never seen or even heard of half & half colored ASC tube traps, but I do know that the reflective versus absorptive side can be identified by the location of the seam. One or the other is centered on the seam, but I don't remember which. Give ASC a call at (800)272-8823.

Ah ha, okay. Were the two-color traps a limited time offering? I’ve never seen even a photo of one. I'll be setting mine back up again soon---I'll have to give them a call myself to find out what the seam side is.
