Of course, do the bulbs and thus fulfill their purpose. But that can indeed identical products from other manufacturers. What made a positive impression on the pin base lamps from Osram: the packaging.
The lamps have not thrown in the cardboard box, but packaged separately dustproof. I already had to experience different with chinaware with a very short lifespan. Who buys cheap ... Well, you learn from.
Therefore: rather spend a few extra cents and buy the Halostar. At my closet in the bathroom, only one light source of three was broken. The 20 Watt Halostar is optically in brightness with the other two identical bulbs (also 20 watts). Therefore, in this regard full 5 stars.
