For LED lamps with the consideration of the wattage of approximately 1 Watt, the best LED lamps I have ever had. The brightness of 140 LM is very well suited for LED 1 Watt lamps and much brighter compared to Andren LED lamps with the same wattage. The light color is super, unlike other LED lamps. I always pay attention to a very high color temperature, in this case 3600 K was in the description given, so it should already be a very high warm tone. (With many LED information always 2700 K to 3200 K are given and are designated as already warm hue) These LED lamps in fact the color is much warmer than others. This affects the lighting of the room very positive. Beautiful pleasant warm and cozy shade and not this cool white. (Although is always a color temperature specified with the other LED's as warm white) so watch here on the color temperature, the higher the warmer the light. Here again clearly the comparison to halogen lamps with 20 watts it is still something else (light intensity and color temperature significantly higher in halogen), but it has in halogen also a lot more electricity costs, who's bars can be should therefore at Halogen stay. ;-) But these LED lamps are compared to other LED's the best I've ever had, even though the first impression does not promise much. (Packaging with Chinese lettering, shipping from the UK, delivery time 2 weeks) ohje I just thought, but when I had installed these LED lamps (basement office with 20 LED recessed ceiling spots) I just ordered again. It really is a hammer price 1.40 per LED bulb. One small gripe I would have but still a pity that the LED lamps have no glass cover on your lighting side, when inserting one comes so with his fingers on the SMD LEDs and with the locking ring should consider when running a little care. However, I would think for a production with glass of cheap price of 1.40 can not be held therefore just a little care when inserting!
