April 12, 1943

A new fluorescent material which produces a warm yellow color when exposed to ultra-violet rays instead of the glaring white or bluish-white color characteristics of present-day fluorescent lighting has been discovered by Dr. W.A. Weyl, American Optical Company research scientist and professor of glass technology at Pennsylvania State College.

Above, the scientist's face is illuminated by the new fluorescent which has been made to emit light by invisible ultra-violet rays generated by the lamp at the right.

A laboratory development, it is not yet available to the public.
