However, 10klux seems a bit too much, given the energy needed to drive the lamps and overall lamp brightness. Too much light can also have negative effects on the eye and moreover, you would just be unable to read your screen well at 10klux.
Nice overview. One small nitpick: `right of=<label>` is deprecated, instead you should use `right=0cm of <label>` (after loading the `positioning` library), which is more flexible. If you don't want to specify the distance, there is also `right=of <label>`. See 17.5.3 in the manual.
