Bentham manufactures a range of equipment to facilitate the measurement of LEDs in accordance with CIE127 recommendations. The CIE defines a new quantity 'averaged LED intensity' and is specified for two geometries, CIE Standard Condition A and Condition B. These requirements specify a detector with circular entrance aperture of 100mm2 area and measurement distances of 316mm for Condition A and 100mm for Condition B, which are fulfilled with our LED intensity tube that incorporates a small integrating sphere.
