The lamp feel like erasers. Because they do not but are warm and energy efficient radiate a pleasant bright light, I can only recommend. Since some 12V-transformers are not suitable for LED, I currently have combined old and new bulbs to prevent flickering or turning off the lights. With a ßgeeigneten for LED power supply (costs about 9) is likely the flicker-operation be possible. Note: LED is slightly larger than Halogenbirnchen, therefore not necessarily fit into any light socket. In some cases, the glass cover can not be completely set up.
