Actually Recommended ..

First things first: It's the best G4 base LEDs that I had previously. I've already tested quite a lot of alternatives to 20W Hallogenlampen, but are now no adequate replacement.
Until now, the LEDs are good this actually as Hallogenersatz.
Both color temperature and brightness come pretty close in the direction of a 20W Hallogenlampe.

Nevertheless, there are of me 1 star deduction:
-The Lichabstrahlwinkel could be wider. Backward they emit nothing. When used in hanging lamps, the upper half of the room and the ceiling is barely illuminated. (This behavior would be a plus point for table lamps!)
- The light box is not homogeneous color.
I put the LEDs in clear lamps one (ie glass with frosted / getrahlter surface). The light caused on the glass surface by the inhomogeneity brown spots.

Conclusion: I'll definitely keep because of the energy saving effect significantly covers the two (small) blemish.
