You really need a photo of the dimmer module itself. For example, Varilight do adapters to fit their dimmer modules into various makes of grid system - so recognising the make of the grid system doesn't definitely identify the dimmer behind it.
Plus, there may be different models of dimmer from the same manufacturer, and you'd only identify the model from the module itself.

If it's Click it will be the MD150WH, but this is just the mounting kit.

Like @Simon47 stated. You need to look at the actual dimmer module; examples > Dimmer Modules
