With 400 lumens, this LED light source brings a comparatively high luminous efficacy. Four of these lights are our 10sqm kitchen incredibly well. The color temperature does not quite halogen and is slightly whiter, as you would expect from LED. For our taste however, it is not too bright. "Replaces 25W" in my opinion is reaching for something low. I bet more on replacing 35W halogen or 50W bulb.
Now they have to keep only a very long time! I'm optimistic but voted for experiences with other sebson bulbs!
