I have long been looking for a quite a dark locker in about reliable light source from the power supply independently, but this should be sufficient light and reliable. After several, all unsatisfactory attempts I am met with this light strip, which holds for all possible tests at last what it promises. In short, when you enter the locker now, automatically switches the light on and spread sufficient brightness. In addition, the whole system is very energy efficient and designed to operate with a few good battery, which can also be substituted by design relatively easy, almost no additional cost. I want the now no longer miss. Highly recommended!
