// NOTE 1: Setting the initial value of the Brightness Characteristic to 50% does not by itself cause HomeKit to turn the light on to 50% upon start-up.
// Rather, this is governed by the initial value of the On Characteristic, which in this case happens to be set to true. If it were set to false,
// or left unspecified (default is false) then the LightBulb will be off at start-up. However, it will jump to 50% brightness as soon as turned on
// for the first time. This same logic applies to the Active and RotationSpeed Characteristics for a Fan.
// NOTE 2: The default range for Characteristics that support a range of values is specified in the HAP Section 9. For Brightness, the range defaults
// to min=0%, max=100%, step=1%. SpanRange(min,max,step) can be used to over-ride this default. SpanRange is generic and can be used wih other Characteristics
// that support a range of values, such as RotationSpeed. Whenever a new SpanRange is defined it is applied to the most recently defined Characteristic.
// It only has an effect if that Characteristic utilizes ranges.
// RECOMMENDATION: Using SpanRange to change the minimum Brightness from 0% (the default) to 20% (or any non-zero value) provides for a better
// HomeKit experience. This is because the LightBulb power is controlled by the On Characteristic, and allowing Brightness to be as low as 0%
// sometimes results in HomeKit turning on the LightBulb but with Brightness=0%, which is not very intuitive. This can occur when asking Siri
// to lower the Brightness all the way, and turnign on the LightBulb. By setting a minumum value of 20%, HomeKit always ensures that there is
// some Brightness value whenever the LightBulb is turned on. The same logic applies to other range-enabled Characteristics (such as RotationSpeed).
