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.
