They work by sensing motion and thermal changes, so during storms they can
act erratic

Is it normal for falling snow to make a motion sensor turn the light
on, or do I just have a crappy sensor? It stayed on almost all night
from the falling snow until I finally shut it off completely. I just
bought and installed this unit a few weeks ago, so it's going back to
the store if it's just this particular brand or model. I bought this
thing to save electricity, not waste more.
