Photometric Testing
At LIGMAN’s photometric laboratory we have an integrated sphere and
the latest full-scale goniophotometer made in Germany by LMT to strengthen LIGMAN’s photometric test and measurement capacities. This demonstrates our commitment to continual development with our in-house capacities for providing global markets with products of the highest proven quality.
Our photometric laboratory can generate photometric files such as IES and Eulumdat LDT. Measurements are executed in accordance with a number
of international guidelines, most notably IES LM 79-08 2007, CIE publication 121-1996, EN 13032-1:2004 and IES TM-30-15.
