In the meantime, the third GEV Staircase lighting in operation, which for me the concept staircase lighting function width of the article completely restricted. In reality, this light can be used at all places - at mid-height shelf lying (horizontal), mounted vertically on the wall and now the third of our loft. The batteries last up to 5 months (depending on use) and are operated by award-efficient batteries. This was also the reason now to buy the third "candlestick" for the loft, which acts as a store room with us. Upon entering the light turns on and gives me easy access to the somewhat remote light switch safely. Once light falls on the unit, it turns off immediately - which in turn helps the longevity of the batteries!
An ideal helper as a night light, orientation and much more - it will not be the last LED light! 100% Recommended!
