I mainly worked on the light boxes today, which began with cementing them up and adding the light tape. The adhesive that comes on the tape isn’t very good, so I usually put 3M VHB tape on first, and put the LED tape on that.
Like Korm predicted, the glow from the white box was too much. The electrical tape seemed to seal the edges of the removable back just fine (the other edges are sealed with the cement, but I’ll probably run some silicone RTV around the interior just to be sure). So I cleaned the box exteriors, painter’s-taped off where the electrical tape would go, and shot them with a couple coats of flat black.
Here’s one of them taped back up with electrical tape and propped against its flat. There’s some shine-through, but it’s minimal, and this is only seen from the ‘backstage’ area. The edge bleed will be better once the box if secured to the foam board.
The box’s interior is around 5/8" deep, so should be enough to put curtains & stuff in there.
Thanks for viewing,
