Works flawlessly, even with dimmer, but too dark

I want to use the part instead of a 150 W-rod in an uplight. That goes without problems, because the space is not critical here. Advantages are the low temperature (less dead insects) and low power consumption.

The light is very focused compared to the halogen tube, so that the ceiling is illuminated only to a significantly lesser extent, and therefore it is much darker than before. In addition, the light color is not so nice (which is of course subjective); it changes (as opposed to halogen bulb) not even when dimming down (which anyway hardly comes into question because of the darkness).

With the lamps you are on the right track, but the last word is not yet. I hope for further developments, the 118 mm R7S socket but probably not as fast as in the standard versions in.
