... I have paid attention to the color temperature of max. 2700K (about 3000K is "never" warm white). Due to the spectral color distribution is the max. Color temperature it is just as valuable as the statement "my hi-fi speaker has 300W". Whether the box therefore sounds really good? The color temperature provides no more than a first, albeit important information. Today I received the National Electronics LEDs GU10 3.5W 320lm with good light output. And? What can I say ... my Osram halogen lamps with 35W replace easily! The emitted light is "felt" a little colder - but subjectively as bright as 50W Osram halogen lamps! ... Cool!
