The above, or just a 90 degree PVC elbow (diameter based on fan size) and paint the inside of the elbow black.

thanks, videos actually kinda helpful, already tried a similar design, just wish i could get the info without listening to this dude blubber on for three five minute videos..

I built two of these for my intake and exhaust, but didnt like the added noises from the airflow, and the fans working harder, btw image is from born to do it right here on RIU,here's a link to our origional thread in the RIU PC gang http://www.rollitup.org/groups/rolli...ggestions.html thanks again man

You should have carbon filters on exhaust fans that block light. Smok4 on another forum used PC fan guards with thin layer of carbon in pantyhose squished in and fastened on.

You can make a variation of this (https://www.icmag.com/ic/showthread.php?t=135524) using plastic corner guards from home depot painted flat black.

I just made a modified version of scrubninja's light trap (above drawing)

I used z channel flashing in a wood frame. I have couple construction pic in my linked thread. Should have finished pics up this evening, will let you know how it works. Without paint still lets too much light through

Yeah, please keep me updated and lemme know how it works out.
