Its the cheapest wooden strips at home depot in the section with the door frame strips. Its like 88 cents a foot. And I just used some small nails to attach em to the wall.

I'm planning to add your light trap design to the outside of my "medicine cabinet," 7th1der so thanks for the idea!
Your wood strips look to be about 1" x 1"? Considering the airflow constriction and the suggested mod to build it a little deeper, I found 2" x 2" flexible foam weatherstripping that I was thinking of using, with foam signage board as the flat piece.
I've just finished painting the sides of the cab and the under/inside of the foam board with flat black acrylic craft paint. I'm hoping latex caulking will work to adhere the foam strips and the board because the weatherstripping doesn't have any pre-attached adhesive on it - it was made to go around window-mounted air conditioners.
I can't promise to post pics but, I'll sure let you know how it works!

You could also incorporate a muffler design into it even though it'll slow the CFMs. and it is a basic muffler design already but a second protruding board would muffle sounds as well. There all ready slowed down by the shallow channel if you build the channel deeper it shouldn't matter but at least your grow box would be light and sound proof.

The noise from my computer fans isn't a prob but, if I could find a way to muffle the exhaust/scrubber fan, that'd be nice.
Anyway, I used a carving knife to rip the foam rubber strips to 1" x 2", then attached them on their sides to the foam board so it stands 2" from the side of the cab. Also, the latex caulking worked well to secure the strips to the foam board (because they had time to set up) but, I used double-sided carpet tape to stick the whole works to the cab. Mofos are on there good now!
Thanks again for the idea 7th1der.

Do you use some sort of ducting with your exhaust because if you do you could add a inline muffler. I'm not sure if you've heard of GrassCity but i have seen an excellent tutorial on how to construct one here.The noise from my computer fans isn't a prob but, if I could find a way to muffle the exhaust/scrubber fan, that'd be nice.

Is it possible to get a night pic with the pc, just to see if any light leaks out the fan?

Hey guys
Did you figure it out?
I had the same problem and my quick fix was i took an old light proof curtain that i used to use in my living room and cut it in strips wide enough to cover the length of any opening and then just duct taped each side.
100% light proof
Hey i realized this is an older theead but i just stumled across it and read a post awhile back about you having trouble with a hinged opening 7th.
