I changed in my office two conventional E14 bulbs with an output of 40 watts and a light output of about 415 lumens (lm) to the two new LED spotlights. Thus I consume today only 8 watts compared to 80 watts of power. This is thus great!
Since the LED lamps have only ever 60 LEDs the luminous efficiency is unfortunately only half as large as that of the two old bulbs. This is also clearly visible.
What means in the LED lamps but still me most disturbs the color temperature of light. Although to the LED lamps emit light with 2900K Warm wise and would thus come very close to an incandescent lamp, but this is not the case. The light still seems a bit colder than the old spotlights lamps.
I will not buy me this product again. But certain other LED lamps test until I've found the right.
