I am satisfied with the product of price or more. Since there is a danger of damage etc., I have never purchased a fluorescent lamp, but I was interested in stunning packaging. I understand that corporate value is evaluated.
Since it was used in the living room, the lighting time was long and it was obviously darker than the room next to the one purchased at the same time, so I exchanged it. It is brighter than the fluorescent light of the room which is rarely used. There are things that are cheaper if you do not consider brightness and life expectancy, but I think that it is sufficiently affordable considering the trouble of replacement and the brightness. Because it was difficult to attach a little because of elliptical cross section, I removed the main body from the ceiling and installed it. I do not use the effect of UV cutting yet to the extent that I can feel it, so I expect it in the future.
