Question about Radion lights

[fido19]

yeah man i really want a bracket like yours
well pat him on the back for a job well done
oh and regarding your question
your height for the light is good you can go a little higher for more spread but you will loose intesity, mine sit at about 9 inches from the tank and it does the job well
regarding the profiles there isnt a way you can switch them without using a computer(as far as i know)
regarding to see which profile is running it will be the profile that you loaded into the software you can check from the project menu
