HP880D Mini 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 light shutter, eliminating the need for a darkroom. Test distance is selectable, and the testing method meets the requirements of 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 luminance distribution curves, brightness limitation curves, ring flux, glare rating, lamp efficiency, effective beam angle, uplight flux ratio, downlight flux ratio, total lamp flux, effective flux, utilization factor.

HP880D Mini Distribution PhotometerThe EEI energy efficiency index can be tested, with the tested lighting fixture capable of rotating around both the vertical and horizontal axes, with a rotation range of ±180°.

Test methods meet the requirements of CIE and national standards.

Photometric Detector V () has a high correction level, meeting the national level 1 illuminance meter requirements.

Automatically plot the intensity spatial distribution curve (polar and rectangular coordinates) and automatically determine the light beam angle

Measurement data meets international and domestic standards; output in IESNA file format, directly callable by other lighting and fixture design software.
