I have the lamp used as a substitute for 12V / 35W halogen with 60 ° scattering angle and am absolutely thrilled. This is the first lamp that works with the existing electronic transformer and upstream dimmer without flickering, and this a very pleasant light color (827) similar. the halogen spotlights has. The illumination is almost as good as that of the halogen lamp with 60 ° despite the indication of 36 ° in the data sheet. If the service life still nearly reached the 25.000h indicated, the change would have been worth in any case.
