The lamps have been used as a replacement for 20 W halogen spotlights on ceiling rails. The light output is slightly lower mE, I have therefore used an additional radiator. The light is warm white, but the yellow light portion of halogen is more intense. The decisive advantage is the enormous energy savings at a total of seven lights (140 watts versus 28 watts). The lamps are one month in use. I am satisfied and would recommend a purchase.
