💡💡 lights

A command line tool for circadian lighting at my desk.

Note: This code is meant for my own use, written as a lab day project, do not expect much.

    	the address of the Key Light's HTTP API (default "http://keylight:9123")
  -bf value
    	set Fill Light brightness to an absolute (between 0 and 100) or relative (-N or +N) percentage
  -bk value
    	set Key Light brightness to an absolute (between 0 and 100) or relative (-N or +N) percentage
  -c	calculate and set the appropriate circadian lighting values
  -i	display the current status of the lights without changing their state
  -tf value
    	set Fill Light temperature to an absolute (between 2900 and 7000) or relative (-N or +N) degrees
  -tk value
