Very astute observation. For power consumption purposes, capping the values of the NeoPixels to 127 is a really good idea. I'm not sure if it quite cuts power consumption in half... but it gets close. There may be some color shifting, though, because our eyes are more sensitive to some colors (greens and yellows, in particular). At some point if we REALLY want to get anal about this, we should do some sort of perception/calibration on only using half of the range... and we may want to cap reds and blues at a higher number than the greens, since our eyes are more sensitive to the green hues.
