That applies to the bog standard halogen type as well, ours is almost
horizontal to keep the "hot spot" out of the eyes of approaching
drivers.

I know this because I am on the receiving end of one.

There are a couple of flood lights at a farm the other side and a
further down the valley. We are 3/4 of a mile and 300' *higher* than
that farm but those floods give enough light to read by up here...

I do try:-)

The 125 Watt halogen reflectors can't be tilted down to keep the light
on your own land because the sensor gets in the way:-(

I suppose this could be overcome by changing the mounting bracket but
for a *use off the shelf* item, this is poor design.
