The lamp is very compact and can be thus easily install in closed ceiling lights. If the bulb is not vertical (ie with the glass body down) but horizontally (vitreous parallel to the ceiling) must be installed, the viewing angle is merely observed. By design it has no angle of 360 °. Here the effect of a spotlight is comparable, the room is illuminated on one side.
Overall, there are at the LED light bulb but absolutely nothing to complain about. If the promised service life is fulfilled, the price is absolutely reasonable. For me it is a very good replacement for traditional light bulbs, but partly also for energy-saving lamps. Therefore, I have directly ordered more of these lamps and they can, taking into account the Abstrahlwinkles, previously thoroughly recommended.
