Disclaimers: NVLAP Lab Code 577- This report must not be used by the customer to claim product certification, approval or endorsement by NVLAP, NIST or any agency of the federal government. The results contained in this report pertain only to the tested sample. This report shall not be reproduced, except in full, without written approval of the CESTL. * Items marked with a single asterisk are not covered by the NVLAP accreditation. In the event that the recorded temperature is outside of 25 ± 1 C, this is considered a non-standard condition. ** In the event that testing is subcontracted, test results in this report marked with the symbol **, or noted as Goniophotometer, were performed by the subcontracted laboratory identified in the footer on the first page of this report. Subcontracted testing is strictly goniophotometer based. All other tests are performed using an integrating sphere. The goniophotometer information in the equipment list, report items marked with **, or results specifically identified as Goniophotometer, are the actual equipment used, and test results produced, by the subcontracted laboratory. Additional Comments: This luminaire was tested in the base up orientation.
