Bought me these lamps wei but even some break. Many operators have already switched to LED, I am of the opinion If you operate lamps with dimming system they are better again they are cheaper several times and secondly keep this well in 2500 burning hours. These bulbs cost 10 euros and 10 dimming lamps cost 80 Euro schauhen them, come to the same operating hours as an LED lamp. Because you can buy 8 packages for this.
