The Osram Preva HV LED Coin 111 AC 15.5W 3000K 24degrees is a replaceable high voltage LED lamp with a compact design. It is suitable for use in private households as well as in business or public premises. This illuminant is not dimmable, but only switchable. The high-voltage LED has a beam angle of 24 degrees. The beam angle determines the angle at which the light is emitted from an LED spotlight. The larger the beam angle, the larger the illuminated area, but it also becomes less bright, because more area is illuminated.
