How do you change the brightness values for the keyboard function keys?

I'm running Ubuntu 18.04 on an HP Spectre x360 13". My brightness keys work great, however I'd like to be able to change the minimum brightness displayed. For instance, at the lowest possible setting before going black, I have this:

$ cat /sys/class/backlight/intel_backlight/brightness

However this is extremely bright in a dark room. A value of 200 would be more appropriate. Is there a way to adjust this?
