The main advantage of this COB led is that it can be used directly on the wall power source, no needing a power reducer. This one I have bought to replace another one that lasted me only 3 months, despite of using a very good heat radiator and proper dissipation grease. Other 2 of them, are working very well. I guess it is a great lottery. In my opinion there are much things to do in order to create led circuits the lasts more.
