The invention relates to a method and a device for sorting fluorescent lamps in terms of phosphor blends. The lamps have a cylindrical lamp body (1) with a right-hand and left-hand end and with a symbol imprint. The fluorescent lamps are conveyed into an inspection station (10) which has stop means (11, 12) for defining an inspection plane (13) against which the lamp body (1) respectively to be examined bears. A camera (21) is directed onto the symbol imprint of the lamp body (1) respectively to be examined. A rotating device (15, 16) in the inspection station (10) is started up in order to rotate the lamp body (1) respectively to be examined. The camera (21) outputs pixel signals to an image processing system (30), which obtains image data from the pixel signals. The image processing system (30) contains image memories with data for recorded symbols, and an image-comparing device which correlates the image data with the recorded symbol data. The respectively examined fluorescent lamp is conveyed out of the inspection station (10) and directed into one of a plurality of sorting paths via a switching system (25).
