If I buy an LED from an established German manufacturers like OSRAM and pay a few euros more, then I expect quality. This LED is indeed also made in China, but convinced both in terms of brightness, as well as light color fully. That behind the milky plastic cover LEDs instead of a filament can be seen really only at low power consumption (nearly 6 watts) and low heat. The viewing angle is quite large, so that the lamp is not exaggerated stands out clearly also in a rice paper lamp and emits in all directions fairly evenly without spot effect light, albeit towards version understandably weaker. A stroboscopic effect as with some other LEDs I have not found.
The loss of brightness through frosted glass (or -plastik) is actually minimal, but it is the absence of glare anywhere. One also sees no single LED light strip or by the glass.
I have the LED even compared with an older, unfortunately unmarked frosted light bulb that draws in words eighty Watt loud instrument almost 80W. In direct comparison, the light bulb is actually minimal and quite a bit less bright yellowish so cool. But you have to look very closely to notice which of the lamps in the paper lamp LED. This has something puzzled me because the light bulb would theoretically be at least twice as bright.
