Hi

I have a security in my drive way, an LED one and mains powered. It will come on, but the light rather than flood lighting the drive is bearly a flicker. The light, when it comes on when the sensor is triggered, is brightish, and then will dim very quickly as though all the power has been taken away. There are no mains issue, and the power that powers the light also feeds the garage. I have checked the power in the garage and everything is fine.

Is this a problem with the sensor or the light? Is it fixable, bearing in mind this is an LED? If fixable, how can I fix it? Or is it a case of getting a new light?
