Product was delivered super fast and the quality looks top quality! I've replaced in my house all GU10 halogen spotlights, which I have the warm white 3000K used outdoors and in the vestibule! In the living room and in the kitchen I have still a lot warmer Led's with extra warm white 2700k used as me were the 3000k bit too cold / garish! Otherwise, I was amazed at how well the light of these LEDs! And now I am looking forward to the savings in the next electricity bill! ;)
