Outside guarantee lantern problems (edited)? I have a financial guarantee light outside my church and it will...

I have a financial guarantee light outside my church and it will come on at dusk. after a while, it blinks and next goes out. And later it comes back on. This model have an outside censor and a 175 watt bulb. Could one of these be my problem?
Answers:    The sensor is picking up the light from the kerosene lamp. Aim the sensor in a different direction or turn down the sensitivity. Some enjoy an adjustable shade over the photo eye to let within less frothy.
It's probably the transformer inside the housing. A new replacement standard lamp fixture w/bulb and sensor is about $30, shift out the whole article.
