Have ordered 7 pieces as a substitute for 12V 20W 100 ° halo. Brightness of the lamps is considerably better The light color is cold-setting - low contrast to halogen. (Me gefällts) Beam angle is very large 120 ° - for a very good room lighting The temperature development of LED lights is slightly lower than the 20 watt halogen lamps.
As in the evaluation of Reinhard G. I also encounter a disagreeable 100Hz hum. My solution: man must be at least 1 of 7 LED lights by the old halogen bulb replacing and 100Hz hum is gone. 7 lights are pretty bright. (This I had with LEDs from other manufacturers).
