The difference between Holophane and other lighting equipment is that Holophane engineers have made a study in detail of all the various lighting applications an instead of offering standardized reflectors or enclosing globes to spray total areas with light, have developed a series of specific units delivering the most suitable light pattern for the area or process involved. The result is greater intensities of illumination for reasonable current expenditure and equipment mechanically suited for the use to which it is put. The reflecting efficiency of an optical prism is the greatest of any known medium being 99.4% plus. This is the secret of Holophane’s High Initial Efficiency. Holophane offers unique additional advantages in the utilization of light. The application of the natural laws of total reflection and refraction makes possible the design of units with light patterns tat are scientifically fitted to the particular surfaces to be illuminated more light where it is needed High Utilization Efficiency. Glass is the most permanent substance that can be worked into useful shapes. Articles made of glass have been found in a state of perfect preservation in excavations of ancient ruins. Crystal glass units alone suffer no permanent depreciation when subjected to heat, fumes, acids, gases, moisture, and time. Of all the materials from which reflectors and enclosing globes can be made, crystal glass alone reflects light in its true color. All other substances permit selective absorption thereby coloring the light to a more or less degree. It is important to have light of good color value.
