The LED's top people. The size is acceptable because my lamp sockets not offer a lot of space. The brightness is comparable with 33W halogen lamps. Now comes the big BUT: the longevity is not reasonable. After about 3-4 weeks the first LED lamp broke. Well, can happen even once. But 1-2 weeks later already followed the next. So 2 of 5 is clearly excessive. So far, I relied on the LED lights of sebson. Unfortunately, this led people are too bulky for my lamps. So I have to look around further.
