Evaluation Procedure
Evaluation of NGL entries will take place in following stages:
Initial screening
NGL organizers will screen entries by reviewing each submittal to verify that all required documents are included (see required documents section). The product will also be evaluated to make sure all parts necessary to mount the luminaire in its intended application are included and that the luminaire functions properly.
In-person judging
The judging panel will meet in-person to evaluate the entries (see evaluation criteria). Luminaires will be installed and illuminated.
Performance Verification of Finalists
If necessary, photometric performance of entries selected as finalists will be verified through independent testing (according to IESNA LM-79-08) will be conducted to verify results.
Photometric information for finalists will be used to evaluate luminaire efficacy, to verify color characteristics, and to identify potential problems such as unexpectedly high luminaire losses, excessive operating temperatures, low light output, and noticeable color shifts. Test results will be provided to the manufacturer.
Product submission information will be kept confidential until the publication of the NGL results.
