Bought for a retro lamp spots. Due to the short neck, unfortunately they could not be installed. However Osram Halostar fit perfectly. Whether this is due to the lamp or the spots to be seen. Now use them in another 4-burner jet. With only one spot could be this good dim. After inserting all four spots in the dimming range is very limited. To less than about half the brightness, the LED spots can no longer turn down now. Otherwise, the brightness is very good (almost comes to 50W halogen zoom) and the light color is also OK.
