The tubes V-TAC 6140 I have not bought on Amazon, but considerably less at another mail order company. Since I use the basement as a replacement for fluorescent tubes, the natural white version is just right. The tube packaging V-TAC in cardboard case is very stable and therefore to be mentioned positively. In the box housing is additionally wrapped with bubble wrap. The often criticized fact that the starters are hard to come out of the package is not comprehensible, since it after removal of the tube can break open the carton. The installation, if you want to call the insertion of the starter and the tube as an installation, without tools very easy and extremely awkward people (I myself am little craft sent) be expected. The experience since the purchase in August 2014 very positively. Should there be any changes, I will tell the tale. The glass tube avoids the bending of plastic tubes. The matt glass does not recognize the individual LEDs. The built-in rotary device ensures that you can rotate the tube so that the dark and non-radiative part is not visible. The brightness corresponds to about that of the equally long fluorescent tube. At present, the (very inexpensive purchased) tube appears to be a highly recommended product.
