There are two places to find the serial number on a Source Four LED Series 1 or Series 2 fixture. One is found through the UI on the rear of the fixture, and the other is found on a physical label. See the instructions below for finding both options.

If you look through the grate on the underside of the fixture, you'll find a while label affixed to the light engine on inside. This label will have a P/N (part number), S/N (serial number), and barcode.
