Outdoor Night Light Testing

I recently replaced a bulb in an outdoor light which comes on at dusk and goes off at dawn. I tried to test the light during the day by blocking the sensor with black tape. After waiting for over 10 minutes I removed the tape since the light would not come on. The light operates normally during the dawn to dusk period. Can you explain why this happens?

Yea, I get that too. I think it's ambient lighting getting to the sensor from inside the fixture.

Depending on the type of sensor..... I put a rubber glove over it. Those sensor are pretty sensitive.

I do outdoor light maintenance quite a bit and the others are correct. Sometimes you REALLY need to wrap them up to block the light. If it is working fine at night, why are you testing it?

Thanks for all of the replies. Tolyn, I wanted to test the night light during the day to make sure it would work at night. This would have saved me another trip in case it did not work when tested during the day.
