First, the product description does not match the product sold. THERE IS NO RED LIGHT !!!!!! One reads the reviews was already mentioned in some places. Why Atikelbeschreibung is not adjusted? This is misleading! Also of flashing is to be read in the article description. Even that does not exist. The head lamp has two light modes and not blinking. When purchasing products I go from where what is described in the article description, because legally counts only, and since the issue of red and flashing light is (!). THE LAMP HAS These functions do not. So, dear Amazon please adapt or no longer sell as described !!! IP X4? I'm no expert, but "Protected against solid foreign objects with diameters from 1.0 mm" I can understand, but maybe protection against splashing water. That can not be! The lamp is flooded after a minute light fine rain. Fortunately, the board is not got wet. The lamp has been resumed. Petzl writes on its packaging but "water resistant" !!! Never in my life, because then would the lamp splashing endure as described in the standard, but what they do not do real. There is neither a seal nor is the board so protected that water can not penetrate unhindered. Since I am very disappointed by the company. Petzl. I have several bulbs of Petzl in use and am very satisfied with the other products. I use Petz-Headlights for hiking, while Survival Training and fishing. Otherwise always very good quality and workmanship. With this product, I am so not happy, I'll keep it but, as I have it are just as an emergency lamp in the car. Bottom down ... description does not fit, no red light, no flashing, no IP X4 or "water resistant". The product does not deliver what is promised in the item description. The head lamp can be used only for dry weather! Läuchtkraft okay.
