Note 1. The average Luminous Intensity is obtained by summing the Luminous Intensity of each seg-
ment and dividing by the total number of segments. The standard of measurement is the
Photo Research Corp. “Spectra” Microcandela Meter (Model IV–D) corrected for wave-
length. Intensity will not vary more than ±33.3% between all segments within a unit.
Note 2. Leads immersed to 1/16” (1.6mm) from the body of the device. Maximum unit surface tem-
perature is +140°C. For flux removal, Freon TF, Freon TE, isoproponal or water may be used
up to their boiling points.
