Rotating Luminaire Goniophotometers

PSI’s LG-1 series of rotating luminaire goniophotometers are compact goniophotometers for lamps, luminaires, LEDs and LED clusters. They are suitable for manufacturers or institutions that do not have the space, budget or requirement for a large, swinging mirror-type goniophotometer. When measuring lamps who’s luminous flux output changes with burning attitude, such as HID lamps and fluorescent tubes, an auxiliary photocell can be provided to correct for the different burning positions. The LG-1 series have a variety of designs to cater for different luminaire size and shape specifications. They are very user friendly and easy to use.
