LED-lamps are nothing new anymore — they are available in a wide variety of types and sizes. Most of these try to imitate the shape of ordinary incandescent lamps. But unfortunately the illumination pattern from many cheap LED lamps is not all that good. The manufacturers try to solve this with the aid of elaborate LED arrangements and reflectors inside the lamp. Also, while the shape may approach that of an incandescent lamp, it nevertheless doesn't look all that attractive when screwed into an open light fitting, because of the alternative construction.
