The screen printing of the product is different. Can we verify the same product?

We are in need of LED Driver with specification, So Kindly suggest suitable product as soon as possible. Watts = 200W - 275W Output DC Current = 5A (Max) Output DC Voltage = 45V to 55V Dimming option : Analog (or) Digital (preferred)

I wanted to know stwlc68 receiver coil.Is it possible to configure it just by GUI provided for permanent configuration

I suspected that I bought a fake Viper22A, can I tell it from the silk screen? One is obviously silk screen, and the other is suspected of laser carving.
