I have now ordered nine pieces of pears and against the old incandescent bulbs, some with halogen interior, replaced. The 15W LED light comes in brightness to really manage to connect a 150 W incandescent bulb. The light is really bright, but affects an idea colder than conventional bulbs. To protect the LEDs a clear plastic sheath is present. Each purchaser should however pay attention to the size, especially the height of the LED light, because it is much higher than a conventional bulb. The LED lights are now only about 3 months in operation, so I can not say anything because of its durability / useful life. The savings potential is enormous but (15 W: 150 W). Oh, unfortunately, the LED bulbs are NOT Dimmable.
