Query: Burned out in one month.

When I first received 2 of these sensor lights I was most pleased. They have many features, each of which worked well. If I had rated this product initially, I would have given it a 5 star rating. One month has past, with both sensors being used at night only. One sensor still works, but the other already has one LED light completely burned out and the other half as bright as it was just one month ago. In order to replace the LED lights a specialized screw driver is required, for screws that I have not seen anywhere before. Most disappointing.
