CHIPS LED S4 LUSTR V2 / version ?

Hello

I would like to have details on the different evolutions of the lustr s4 v2 cutouts, in relation to the serial number.

I notice differences in the LED and power supply locations. (photos attached)

version 500.xxx                                         version 388.xxx                                version 500.xxx                            version 388.xxx

power supply

Are there color differences between versions ?
