I first bought a LED to check the color and brightness. The brightness corresponds to a 20 W halogen flood something G9 lamp (comparison possible), G9 LED, however, a stronger angle has thus helping to bring up a small spot results (only when compared to a normal G9). The light color can also be still pass as "hot", it is a little colder than halogen flood. Have after the first test "retrofitted" and hallway and living room partially equipped. Am absolutely satisfied. On the packaging are two values durability: even 1000 hours (on the Energy Performance Certificate) and even 15,000 hours as a description. I hope it will be of higher value! By the way, Made in PRC = China. From the dimensions, light values can I use the lamp (s) currently recommend. Will buy myself even more ...
