For Anglepoise products we tend to just use on and off switches rather than a dimmer or dimming as this allows the most flexibility. As many of our customers will use different specialist bulbs that will allow direct dimming through some form of app. These will either be Bluetooth or Wi-Fi bulbs or dedicated systems such as Philips Hue.
If you are however using such bulbs you will need to be mindful of the weight and the overall size of the bulb as it can affect the balance of our sprung desk lamps, or stick out beyond the edge of the shade.
We do however have a smaller product called the 90 mini mini that is USB powered and has dimming control. You can see more about the product here in the following video.
