I bought this bulb to replace a fluorescent bulb low consumption .... however although the cold white light was chosen in comparison with others which are white-cold in my apartment I find that the light is less strong, less natural that the amount of lumens developed are equivalent ... I sent the bulb in its box after the test ... by cons I already has led E14 in my dining room and am quite happy .. . probably because the lighting angle is 140 ° ...
