Unfortunately, the chips do not fit in the spot reflectors, a few millimeters are missing ...
Recommendation: Before remeasure. Visually, the chips could be built slightly smaller. Too bad that was not done.
Have they therefore tried in the bathroom because they fit grade pure. Fortunately, the connector pins are reasonably flexible and stable so that they can bend if necessary, plug it in, and then turn with the chip facing upward when space is tight.
From the light I'm thrilled it appear lighter than my previous 20W spots. And the light color is cream 1a.
For the price of things really okay. How long do they last, I can not say yet.
Currently have a bathroom permanently installed in a mixed mode with a 20W Halo. Works without humming, flickering and bitches. Two go with my transformer not, buzzes and flickers as it. But because the chips can not be sure. Whether I retrofits the transformer to the second bathroom also be replaced, do not know yet. Believe it pays not for a radiator.
Fret does me with the kitchen bar. But could I measure it precisely in advance ....
All in all. Buy recommendation, but first measure it, because they are very large and may not fit into the reflectors.
