I had already tried a lot of LED lighting by but this one is by far the best. An enormously bright clear clean light, despite very small size, just that is very rare. With the 4 bulbs Our living room is finally out will glow really good, did not think that you get such a good light for this course. Also at the processing there is nothing to complain about, very stable and even provided with decent ventilation holes, so that the electronics from overheating during prolonged use. All in all, there is nothing to put out and you get for little money very good bulbs. Now only the question how long they hold but it will come.
