Overview
The LSG-1950 is a CIE A-α Goniophotometer specifically designed to test automotive lighting, traffic signals, bus, train, ship and aircraft lighting. The photometer head remains static facing the test sample while the sample rotates around both horizontal and vertical axes, enabling measurement of luminous intensity and illuminance.
Designed to EN, IEC, GB, ECE, SAE and FMVSS108 standards, the LSG-1950 provides angle accuracy of 0.01° and angle resolution of 0.001°, with Class A photometry accuracy. Testing accuracy is 2% under standard lamp, with stray light less than 0.1%. The instrument can test lamps weighing up to 35kg.
English software runs on Windows 7, 8, 10 and 11.
