Now that the last conventional light bulbs burn out also with us in the lamps, was forced to change for us. Relieved, I was already in advance that it except the poisonous mercury bulbs and bright halogen and LED lights are now also halogen bulbs and LED light bulbs. Due to the energy efficient efficiency of LEDs compared to halogen bulbs we opted for this. I am pleasantly surprised at how hot the yellow light is still, I feared for the yellow hot traditional bulbs often criticized white. The light but pleasant. However, it lights up the room not as good as the previous bulbs, because the corners remain dark and down no longer drops enough light. We have a lamp with gerichtetenn upward pears. First, I will but first buy the same bulbs in 9 watts or more, then we can say only if the light is bright enough to advance. We just need only to the expensive prices "used", but hope that it (over?) Is saved by the longer burning time and especially the much lower energy consumption eventually. But all in all I am very satisfied, the living room is still lit cozy and pears neither too hot, nor flickering or buzzing you! That's very important to me in pears! A clear advantage for us that after the ban of mercury-containing fever thermometers not now have to collect the mercury-containing light bulbs energy saving lamps with us!
