What are the benefits of self-contained exposure units?

Self-contained exposure units prevent the light leakage that can ruin coated screens by prematurely exposing them. Because exposure cannot take place unless the lid is closed, self-contained exposure units can be placed in darkroom with coated screens. Putting the exposure unit adjacent to the coated screens protects emulsion and increases productivity. Self-contained exposure units also take up less space than a separate vacuum frame and light source.
