They light (few: invisible before dark but after all, "that's becoming less" for the environment). The supplied adapter may actually be connected to the wire garlands, with one blade for deburring molded thread (very dubious quality at that level).
Comes the first rain: the water flows along the wire, and infiltrates each (each (Am I clear enough (each))?) Bulbs garland, the passage of the wire in the base of the bulb is not protected. The water then fills the bulb (admittedly removable) to the rhythm of the rain. Oh, do you care occupation, mind you. If he liked it, so put on a slicker and going to empty the bulbs: light bulb on a one minute (you are under water, slide your fingers), time and your two garlands are like new. Oh no, am I stupid: we must already start.
The allocation of IP44 this product clearly holds the exploitation of a flaw of the standard: obviously, a water spray will not create a short circuit, but can we consider that with garland the bulbs are filled with water has withstood the bad weather? And what about the mass of the garland, when completed?
At this rate (albeit modest), one would have expected of a 31st Supplier bulb filled with petroleum jelly. To seal the thread passages in the pellets, obviously. Evil be to him who thinks otherwise. We could also imagine paying ten euros more and see, why not, a point of complete silicone waterproofing product which is a pure fad in the state.
I highly recommend the purchase of this product, and will trust me for my part never to this supplier.
