I agree. Superficially, dimming street lights sound "brilliant". But to
do it right would be very complicated. It's easy to detect motion. But
it's difficult to detect if someone is lurking in the bushes. Also, the
light from the lamps illuminates front yards to some degree. Would the
motion detectors detect movement in those areas? What if someone moves
very slowly. Will they outsmart the detector? Finally, how would it feel
on the inside of your house or apartment if the lighting outside was
going from bright to dim to bright... All of these issues may be
solvable. I'm just saying this is complicated.

As Day becomes the new night for cheap electricity and night will

Have the lights dim to 20% when no cars or people are driving by.

ANd if you watch the video they mention one of my concerns about a
failed
radar on any given pole is mitigated because all the lights also talk
to
each other by RF so that they tell the other lights what is coming.
Neat! Saves 80% of light power while still providing full
illumination
when someone needs it.
I am generally upset at night sky pollution due to excessive night
lighting. But this is a step in the right direction.
Remember what our scities look like at night from the air? What a
waste of
energy...
