Price / performance and luminous efficiency are top. I can not complain about the color myself. Here glows times no wire, so there will be always small differences from the color of light bulbs. But these LED are already very close. I am LED fan and have a long time ago LED lamps (GU10) bought from other manufacturers at a price of about 16. Most of it has landed already in the trash. For life same make (for me the most important buying decision that can hardly answer) I will update this review in a few months. The LEDs are used with me in the hallway, bathroom and kitchen. So many switching cycles and humidity are commonplace. I hope they keep. So far, I give a strong buy recommendation for this product.
