Closed off the 3 holes in the bottom that I was using for intakes. Cut a 12"x6" hole for the new light trap intake that I constructed last night. It works like a charm, way better air flow than the floor intakes and 100% light proof.
Constructed from .5x.5 angle aluminum
Double sided tape (doubled up) for spacers
Flat black spray paint
I get way better air flow now, temps dropped 5 degrees.
Again 100% light proof! To light proof the holes would have been touch trouble.
Box will be 100% plight proof after I beef up the door insulation.
Then I'll add finishing touches like knobs and fresh paint on the outside
