HP880D Miniature Luminaire Distribution PhotometerUsed for measuring the photometric performance of LED mini-lights and single high-power LEDs, the instrument is designed with an optical dark box and a diaphragm, without the need for a dark room. Test distance is selectable, and the testing method meets the requirements of the CIE 127 and IEC 61341 standards.

Luminance levels, IESNA (95, 2002) file format (*.ies), CIE file format (*.cie), European Eulumdat (*.ldt), light intensity distribution, light intensity distribution curves on any cross-section (displayable in either rectangular or polar coordinates), spatial equal light intensity curves, flat equal illuminance distribution curves, brightness limitation curves, annular luminous flux, glare rating, lamp efficiency, effective beam angle, uplight factor, downlight factor, total lamp luminous flux, effective luminous flux, utilization factor.
