HELIODONS   are used to simulate the lighting conditions at a specific latitude, time of year and time of day.   In this fixed sun style the model is adjusted in relation to a mounted light source - a narrow beam flood lamp 30 to 40 feet distant with an output of 600  to  1000 watts, representing the sun.

The most recent device H04 was constructed for the American University in Cairo, Egypt. This device was fabricrated as per the heliodon at Ball State University in Muncie, Indiana. Improvements included on these two instruments are machine engraved scales and a spring loaded split worm gear arrangement.

The original device is at the Pacific Gas and Electric Co.'s  Pacific Energy Center in San Francisco, CA. ( built in 1991 and in still in daily use with several thousand studies completed ) and the second instrument is at the University of Hawaii at Hilo.
