This is not just people on the forum. Many TFP employees would like it darker, myself included.
Ambient light and moon light brightness reduction only happens at a Brightness setting below 50% and 50% is the default, so it is not changing the defaults.
Helmet lamp was a sensible balance adjustment, because the range was way too long and longer ranges lead to worse performance and I actually increased the brightness a bit to compensate for the reduced range as brightness decreases with distance.
