My friend has a 100 watt mercury vapor security light on her garage that for the
most part won't turn off. she's replaced the bulb, it needed it anyway, but the
guy doing her handyman stuff says the sensor has to face north. the wall the
light is mounted on faces east, north faces a 12 to 18 inch roof overhang. seems
like it would make more sense to face east or even south east, but she isn't
sure if the sensor is able to be rotated and since she has a new one to put in
with what looks like a weird electrical outlet three prong plug, I doubt that it
can be rotated. Any recommended fixes?

Hi,
Does sensor have a shade like camera shade on it and/or is there an
adjustment for setting the sensor sensitivity. My El Cheapo 9.99
security flood light has two adjustment. sensitivity, turn off delay,
If there is no adjustment try blocking the sensor opening partially with
piece of black tape like a shutter. May have to fiddle with it few times.
