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

If you have a single colour, the seam side is the absorber.

Hi, thanks bdp24. Yes, I did call them, but the person who answered had not worked there long enough and did not know.

And yes, with one colour there is a single seam so it's easy to know which side is the diffuser. But with two colours, there are two seams; one seam each time the two colours meet one another.

Got it. The light side is the diffuser. Thanks.

Here you can see an image of the two tone tube trap (scroll down the page)
