These lights give a more even spread of light than the halogen bulbs, and are very bright although not quite as bright or focused as the halogens. I have 8 of these now in the kitchen and they are doing a very good job of lighting it, and they cost about the same to run as just one of the old bulbs. I'm impressed with them so far and intend to replace all of the halogens i have with them, as for their expected working life - only time will tell if they last as long as expected!
