Hey guys
At home depot you can get air condition flex duct.It's insulated and has a outer cover over the insulation.No light will get in at all.Or you can take 4" duct and run it inside a 6" duct.Like a duct in a duct.That should stop light too.Well thats all I can think of right now.Please keep us posted on how you deal with the light. Peace
