Power supply (LED driver) specs: "setup", "rise time" meaning?
according to the manual


  Setup time is the time taken for the electronic control to become functional, i.e it's input, control loop are ready to be functional, so that it can start output
  
  Rise time is the time to get a steady state output from the time the device  setup time is completed and started outputting the power.


The manual had stated this time at normal load and full load

You had to sum this timing which is the total delay between when you switch it on and the device start outputting the power
