    It's a suitable LED bulb, but the luminance is not 850 lumen!!! I measured 25 lux maximum at distance 1 m, it's equivalent to 35 W incandescent lamp, so to say approximately 350 lumens. The consumed power is not 4,5W, but really 7W at 230V voltage). The error is flagrant, because 850 lumens for a power of 4.5W is equivalent to a efficiency of 188 lm/W !!! It would be amazing for such a small light bulb.
