light wont bend around corners,a small box w/ a couple bends will stop it from escaping. it does reflect so make the inside black

extend the vent out of the box and point it somewhere where you can't see the light

X2 on the elbow and some flat (not glossy nor satin) black buzz-bomb inside your ducting. I am wrapping up the lamp air intakes for my two-room setup, and used a couple cans of flat black inside the plenum and duct connectors to kill any errant light. I also installed a couple pieces of 2x6 within to act as baffles.

Maybe also a louvered 'dryer vent' piece to terminate the elbow? Paint the inside of it flat black too...

I'd get no sleep knowing light was escaping like that LOL!

Came across this DIY on this site a while ago. Just another option. https://www.rollitup.org/do-yourself/484398-diy-light-trap.html
