I can only agree with the positive reviews, this bulbs are an effective replacement for halogen. They are much brighter than the old 35W halogen that I replaced it and focus the light felt a little less, so that the room is now lit more evenly, but something whiter than halogen lamps, the light color is but pleasant and warm, for me not disturbing. In a direct comparison (I could see well because I changed only one half of the room), the halogen lamps look more uncomfortable / exaggerated hot / yellow.
