First impression: the LED could only fiddly to install brackets, they were not quite as fit as the Halo's.
After the first start I thought Woooow. Hell, the parts are now really. Feels even slightly lighter than the original built-in 50W halogen lamps. Perhaps due to 'whiter' by some impression of light. That's what I'm going to, of course, also in the light, instead of 150W to wasted, only 15W safely used to 'verleuchten'.
Only, and now I do not know - I really am the first person to notice this ?! - Somehow I had the impression that something is wrong with the lights not ... yesterday after installation I thought maybe it was just my imagination. Today I have found the reason: Unlike the 12V LED's in my office, the lamps show here a noticeable strobing for me. If that's at all 240V LED's so, I have to revise my plans further exchange well.
Since this, however, was never otherwise noted, and I find the light yield truly remarkable, there 4 stars.
