Check to see if the fixture has a sensitivity setting or switch. Perhaps it needs to be adjusted or set correctly?
I'm looking for the proper settings for mine now.
Here is THE ANSWER:

At dawn and dusk, the sun is close to the horizon. This means that it passes through more atmosphere. As a result, the sunlight is scattered to the red end of the visible spectrum, and the dust that naturally occurs in the atmosphere closer to the surface intensifies the effect.

Dusk is the period of time at the end of the day when the sun sets.
The time of dusk in the summer, or in the winter, depends on your location on the earth. Within time zones, it also depends on whether you are nearer to the eastern or western edge of your time zone. Dusk begins when the orb of the sun drops below the horizon. According to Wikipedia: "Twilight is technically defined as the period before sunrise and after sunset during which there is natural light provided by the upper atmosphere, which receives direct sunlight and scatters part of it towards the earth's surface."
At noon in Summer, the Sun is high in the sky, so the shadows are shorter. At noon in Winter, the Sun is low in the sky, so the shadows are longer. A winter sun is more likely to dazzle you, as it is lower in the sky throughout its travel between dawn to dusk.

Dawn and dusk skies are red because of the position of the sun, relative to the viewers eye and the Earth's atmosphere. At dawn and dusk, the light of the sun has to travel rather to reach the viewer's eye and has all of its higher energy blue light scattered away by the atmospheric particles.
