The specified number of lumens is not reached in a direct comparison with corresponding energy-saving lamps. But since I use the lamps only as additional lighting for other LED, the brightness is sufficient. 2 out of 15 lamps were broken. Mir were announced respectively 3 Euros per lamp as a replacement. A subsequent delivery was not impossible. Since the lamps are only available in 5-packs, I had to re-order beyond my needs.
