5.0 LM-79 Measurement and Test Results Model No. FLS50U50B/N/G2 Sample ID. Opreate time (Min.) 90 Stabilization time (Min.) 1604001 45 Test Method 1.The sample was tested according to the IES LM-79-2008. 2.Photometric paramters were measured using a type C goniophotometer and software. 3.The ambient temperature shall be maintained at 25 C ± 1 C, measured at a point not more than 1 m from the sample and at the same height as the sample.the reference standard lamp is rated current 3.865A omni-directional Incandescent lamp and was calibrated by china seprei laboratory. 4.The samples were operated at rated voltage and was stabilized before measurement. Luminous flux, luminaire efficacy, zonal lumen were calculated from the software taken at 1 vertical intervals and 22.5 horizontal intervals..photometric distance was more than five times of the largest dimension of the test SSL product.
