but it's true if you replaced all that Tin foil or reflective sheeting and put a solid Flat White surface, or painted with a Flat/satin White 8 Layers! White will reflect light way more effectivly cause with that foil/or reflective sheeting you will get hot spots and light is not being dispersed right. Remember the more light to all your babys the better all white walls would light that bitch up hella more.
