The light string is processed properly, comes with a sealed box for electronics and batteries, and produces a pleasant, actually warm white light (we have other LED lights that seem to have more blue - these are not). It is operated via a fiddly, difficult appealing button, the first suspicions aroused to be defective - he is not, but you have to search for the pressure point quasi. After activating the light chain for six hours and then 18 remains lit hours of darkness. Unfortunately, that can not be changed. However, the function is apparently reliable and quite practical. Be sure to take care that the delivery includes sealing rings for housing and screws! I had to complain the first delivery, and then I only realized when replacing that the seals actually supplied information can include (the first delivery was faulty, the chain could not be induced to emit light, presumably because of the mentioned fiddly stylus that there simply do did not do). Without gaskets moisture is pre-programmed in the housing for outdoor use.
