Given that light falls off at an inverse square rate do you plot the lumnes at source of light, centre of the bed or the observed light at the buttcrack?
If the later, how do you account for different distances from the light source durring a given session?
Clearly there is an opportunity for an entrepreneur to fill this market niche with a lidar smart dimmer light that accounts for the distance of said buttcrack.
I imagined a graph of number of missed buttcrack hairs to the amount of light allowed in a session.
