Have taken them as a replacement for 35Watt halogen. Are not quite as bright, but at 6 Units in 12 sqm for me really sufficient. Have now installed 17 pieces. The light color is not as uniform as with halo, ie the outer cone of light, the light is more yellow than in the center. However, the LEDs are 1000 times better than the 3000K cheap parts !!! Priced at 5.99 I can really recommend it !!!
