The delivery via Amazon came two days! too early. This is only positive. The lamps were well wrapped.
Now to the matrimonial product:
Warm White: The warm white LED has a very beautiful light that is neither too hot nor too cold, and is very suitable for living rooms and the like. It is very bright and replaced quite mind. 50 Watt lamps. Especially in smaller rooms just have a single lamps to illuminate the whole room well. A watt consumption of 7 is the culmination. I already own a 10.5 Watt LED and with this the ordered LED bulb can keep well in brightness and warm temperature, yet consumes 3.5 watts less. A strong buy recommendation. Something better is found to be unsafe in mom.
Cool White: I have ordered 2 pieces of it. The light is me frankly a little too blauhaltig. I can not set correctly, if I can find the light is good or not. For a living room this LED is nothing defenitiv. For the work at the desk, I can imagine the LED are more likely. I will probably return a LED and order 2 warm white. Before, I would try but the LEDs even further and if possible make known again here my feedback.
General: Noise: Hardly. The LEDs are not loud and you can hear only noise when you stand about 30 cm below the LED. Since there are much worse.
The heat development is for a bit more. That was me before not so aware but after a few minutes is the part already more than lukewarm. So you should isolate the LEDs not possible.
The stated life here on Amazon is 30000h. On the packaging there are 18 years with 3h / per day. Now what is true no one can say but I hope there are 30k h :)
Conclusion: Warm White defenitiv worthwhile! Super LED.
In cold white rather first order one and look at the light. The light with 6000k color temperature will not please everyone. There is, yes, but not in vain, the 3000K version.
Full 5 points from me for that E27 LEDs.
