Just be aware you will not be able to use a HUE light with directly connected dimmer.

If you want to be able to ‘dim’ a hue light - rather then adjust voltage - as you would in a normal globe - you instead need keep the voltage constant and to inform the globe to dim itself.

The alternative is to use a dimmer/switch which is not connected directly to the globe, which when adjusted triggers a flow which adjusts the hue globes brightness. (ie. Smart wireless controller : [https://www.fibaro.com/en/products/smart-switches-and-outlets/](https://www.fibaro.com/en/products/smart-switches-and-outlets/)) or [Smart lighting | Philips Hue US](https://www2.meethue.com/en-au/p/hue-dimmer-switch/8718696752029)

But to answer your question, the standard way is to use a device like fibaro/aeotec dimmer hooked up to momentary button switch. - Which by default will adjust the brightness by holding the button down - and double click to go to 100%.
