Comment(by AlbertCahalan):

 Agreed, the minimum is too bright for use in darkness.

 Humans have non-linear perception of light. The current step size is too
 small at high brightness, and too big at low brightness. Output would
 ideally be proportional to the input raised to the 1.8 power. Quadratic is
 close.
