As the E-switches can work without interrupting the light being on, it allows for fancier UI than physical switches. It seems many people prefer the good e-switch UI. For example, Click on; Click off; Hold the switch to change modes, normally cycle from lowest to highest, then back round again to low; Shortcut to turbo with double click; Shortcut to moonlight with holding the switch from off; 3 or 4 clicks to lock/unlock the light… And there are also other users telling they like tail switches for turning on/off with modes controlled by either rotary ring or separate switch. A good UI is easy to use. How about your preference, what the user interface and controls do you like? We appreciate your kind comments and suggestions on this!
