Items are of high quality and working fine.
Although I left a 5 star feedback, it is good to say the type of LED I received has a lower power than the declared power. According to my measurements, at a voltage of 6.2v the current is about 80mA (0.5W) and not 2W as declared. But compared with another type of 6v leds, this led is one of higher power and therefore I am satisfied with this purchase.
