Not so this LED lamp. Everything is just right. The brightness is subjective even a little higher than that of a 40-watt bulb, the viewing angle is directly comparable, though the light field in the bulb is usually not as homogeneous as as is the case with the LED lamp. A uniform illumination of large areas is thus excellently possible. And the last common gripe with LED bulbs can also be completely dispelled from me: the light color is so natural, as I have never seen non-incandescent. Warm white is just not the same warm white. Because of the completely different nature of light generation you will never actually achieve a 100% agreement and it remains even in very critical viewing only a loss of atmosphere compared to the continuous spectrum of an incandescent lamp. I personally am, however, prepared to accept for 80% energy savings in purchasing.
I like it very much, for example, my 4-ring corridor lamp now 20 instead of earlier to fire with 160 watts and about without sacrificing light quality, or even up times. The limitation of the scope (not dimmable, not waterproof protection class IP20) has to be clarified in advance, but plays well in practice often not matter.
The high rated life must still prove the lamp as long as there is no corresponding addendum to this review I stay with a 100% buy recommendation.
