Light intensity: very well. equivalent to a 50W halogen. Quality: very well. finishes look ok, the bulb is smaller than her sisters "classic". on 4 bulbs ordered all work. Light color: warm white is announced but felt much colder than what I expected. for buying other spots and LED bulbs, and comparing with halogens I had before, it's still frankly colder. probably the only negative of the product. intestable: longevity.
