I'll never going to use above light setting 10, so is it possible to just darken the overall light settings?
Even at 1 it's still light enough for me (like not too bright, but still I wished I had one more darker setting for reading in the pitch black).
No you can't get any lower light (other than off). This is how the lightlevels of the light slider on screen correspond to the level of the actual device:
level 0 - device 1 level 10 - device 13 level 20 - device 147
level 1 - device 2 level 11 - device 19 level 21 - device 170
level 2 - device 3 level 12 - device 26 level 22 - device 196
level 3 - device 4 level 13 - device 36 level 23 - device 224
level 4 - device 5 level 14 - device 47 level 24 - device 254
level 5 - device 6 level 15 - device 60
level 6 - device 7 level 16 - device 75
level 7 - device 8 level 17 - device 90
level 8 - device 9 level 18 - device 107
level 9 - device 10 level 19 - device 126
As you can see up until level 10 it goes in small steps. No wonder Amazon does not list any battery life time for light higher set than 10 (if the numbers for the intensity are any indicator for powerusage). Plus as you can also see, it gets larger fast - theory of me is the logarithmic scale of light - to make a bright light visibly brighter takes a lot of juice.
I have also worked out a way to turn the light off. It already works on my PW - every time my PW wakes up and the light is set to the lowest level (no bar on screen) it turns the light completely off, but only once on wake up (no messing with the crontab file). If I go to the light setting and turn the light up, it will turn back on, even if the slider is set back to 0 - it will stay on the lowest light. To turn it off again it is necessary to put device back to sleep and wake it up. To make it even more convenient, there is a file that needs to be put on the usb partition to enable the turning off of the light. So it can simply be renamed or deleted if the automatic turning off is not desired. Put it back and it turns back off next time you wake the PW up.
Now I only have to pack it into an update_*_install.bin so that it can be used even on PW's that don't have USB Network installed.
