The 'warm white' is a bit less 'hot' than halogen spots that these bulbs replace but still very enjoyable. The cone of light is 38 °, such as halogens, but gives the impression of a light a little less diffuse - but the area covered is very acceptable. I had originally bought a spot at Ikea which I was very disappointed, I'm very happy contrast of it. I was in my room 4 x 50W, I now have 4 x 4W. I will equip the rest of the apartment with this product, I recommend.
