The spots should serve as a replacement for 35W halogen. In principle, the illuminated areas are at least approximately the same brightness or rather even a little more brightly lit by the Lichbündelung to 33 ° as with halogen, which emit the light cone wesentich wider. But overall, the room seem darker and not as bright as halogen. These LED spots are therefore certainly not a replacement for 35W spotlights. What strikes me, the LED spots are quite hot during operation. I am therefore not quite sure if this is actually only need the indicated value of 4.5 watts. Light color: this is OK and really warm white. One of the 4 ordered Spots contacts when assembling the pressed despite careful treatment in the housing, which causes the spot just does not make contact with more power and thus falls well out of the socket. This is fall out then yes even matter, is indeed no longer be used ... so back to the defective spot on Amazon!
