Man's effort for thousands of years to get more and sharper light culminated i n electricity. He overshot his mark in produc ing a direct glare of an intensity dangerous to the eye, yet an imperfect luminant because of its uneven distribution. Glare in one spot means gloom in another. The same science of optics which revealed the destructive effect of the modern lighting evil has also supplied the corrective and the cure in Brascolites. Following optical principles, the makers of Bras colites have adjusted and adapted electric light to the service and the protection of the eye. By In the specialized field of industrial illumination scientific study and in ventive genius have produced In dustrolite. This fixture combines wide distributive service with per fect eye-protection-low cost and low depreciation. It is an even effi ciency fixture, sanitary and easy to clean; calculated both to increase safety, production, and quality of workmanship, and to decrease mis- I Accurate calculation and uniform distribution of proper light ing units means not only economy of eye-health, but economy of cur rent. The ut most and widest use made of light units without waste cuts down cost. Brascolite saving is measured in the meter. Brascolites are built in a wide range of design, adapted for special uses in the home, in offices, stores, hotels, theaters, railway stations, restau rants, libraries, clubs, schools, and everywhere else that good light is necessary. On request we will send you a portfolio of photographs showing the variety and character of installations now in general use. takes, accidents, and costs. Spread ing a uniform light over a broad working area, Industrolite is the ultimate solution of the factory lighting problem. The services of our engineering department are at your call for con sultation and expert calculation of your lighting requirements. There is a Brascolite dealer in every city to make demonstrations.
