It seems that aluminum foil has the best reflecting ability, but I sure see a lot of white painted walls. Then there’s panda film, and a vast amount of reflecting materials. Why doesn’t everyone use aluminum foil, spray adhesive’d to styrofoam insulation board to keep from having hot-spots ? It seems the most useful of light capabilities ?

I saw a meter test that proved very, very different, so I was wondering why the gurus don’t use aluminum foil ? People do use it. The readings were off the charts better than white paint.

Sounds like the route many took according to all the videos I’ve been watching. See, now that’s what I was looking for. I was wondering if the tents reflective surface was textured as to prevent burns and hot spots. Maybe the foil works when you’re very under powered ? Amplifying what little you do have. See, still a plan in the works, lol ! Thanks.
