In our stairwell 6 x 60 watt installed, burn about 1 hour per day. This 360 Watt power consumption has now been reduced to 48 watts, which brings an annual saving of about 25 Euro with it. After 2 years, this 6 LED lamps have therefore been amortized.
Therefore, we ordered the 10-pack and got a truly presentable LED lamp supplied for 8.30 Euro / piece. The transparent frosted glass is not as usual from cheaper plastic instead of "real" glass. Processing acts normal to good and the LED lamp removes about the same place.
The corncob form has been better because we have a uniform light output here in all directions to us. Alternatively, the pear shape order (here: http://amzn.to/1FNXYtz), or the light in the 160 ° angle forward emits upwards.
The old bulbs have now been replaced and the luminous efficiency of LED lamps can be more than excellent! They even give off more light than conventional light bulbs 60Watt. Our 53Watt halogen bulb (this here: http://amzn.to/1xD8t0e) in the bathroom was also also changed the same and also here we have a brighter light. I do not judge whether it is due to the number of lumens or light color, because the LED light is something whiter than the conventional warm yellow / white now. It is for me anyway a pleasing color combination of bright yellow gaaaaanz much light.
The lamps are also more well packaged: Individually in a box, in a specially Kunsttoffhülle before fall well protected.
I can not judge about the durability. If something negative result I'll let them know!
