Hi

I am after a dimmer to control the intensity of a floor lamp.  

I cant seem to find any in NZ and wonder if this type of dimmer is not for sale due to safety reasons etc. 

One that I can wire in-line would be preferred.  (the other option is a standard wall dimmer in a conduit box but that is going to look messy and ugly)

Below is one from AliExpress that I like, as it is foot operated rather than a dial knob that you need to reach with your hand.
