I have purchased this tube - light from mall and I am not satisfied with its performance when I on the light it takes much time to get on. After that the fuse had gone so I complain about it and I want money back, but they don’t give my money back but they get it replaced it after a month. When I turn on the new one it work correctly but I observed it catches the eye focus and it create eye irritation. It also take much energy than an ordinary tube -light. I was greatly disappointed with this tube -light.
