The fluorescent frames, for their correct viewing, need blacklight. The idoenas conditions are a space illuminated with blacklight, since the daylight subtracts luminous power and annuls the fluorescent effect. If the exhibition space has a daylight, you can still have optimal viewing conditions, if you use the frame with built-in blacklight that you will see in the photos below, depending on where the daylight comes from, you can put a protector on the side that suits you, to avoid interference with the blacklight.

When the painting is not going to be viewed, for optimal conservation, it is necessary to cover it to protect it from sunlight, as you will see in some of the pictures that appear in the photos.
