Lamps are very well made, clean-fitting pins. But you should keep in mind the space, I had to use with pointed fingers in a table lamp from the outside. The removable lampshade does not go beyond the lights. The light is a bit weaker than the previously mounted Halos with 20 W. I would estimate that the light output closer to 10 - 15 W halogen light .The is pleasant, has a very slight green cast. In my view, but perfectly OK.
