Had one of these on the garage for about a year, recently the light remained on constantly, and once the supply was switched off and on again the light failed to work!
After replacing the light for a new one, everything was fine and it worked for a day, then the new light failed exactly the same way!
The light was on constantly, so we had to turn of the power and once we turned th power back on the light now fails to work??
It seems to me like the sensor has failed, but what would cause this problem??
