Worklights are not designed to light the stage in an aesthetically pleasing way, but rather to be efficient in terms of space and heat; however, they may occasionally be used to emphasize plot elements during a show. They are generally near-white.
While worklights aren't designed for visually appealing stage illumination, their primary function is to be energy-efficient in terms of both space and heat. However, they can sometimes be employed to accentuate specific scenes or plot points within a show.  They tend to emit light that is close to white.
