The average Luminous Intensity is obtained by summing the Luminous Intensity of each segment 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 wavelength. 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 temperature is +140°C. For flux removal, Freon TF, Freon TE, isoproponal or water may be used up to their boiling points.
