LIGHTWEIGHT AND COMFORTABLE – you won't even notice wearing it. Weighing only 3.2 ounces (with batteries) with easily adjustable, ergonomically designed elastic headband makes this light perfect for long distance runners looking for a comfortable fit.
SUPER LONG BATTERY LIFE – by using leading CREE – 3W technology MX20 provides more light with less power used, resulting in up to 45 hours of run-time. 3 AAA ENERGIZER batteries included. Each head torch has been tested for quality.
At present, the recycled materials produced in China are difficult to distinguish because the waste of many factories is either impure (ie, containing impurities, such as ABS, etc.), or the PE content is very heavy (because PE is added to PP to reduce costs). Recycled plastics produced abroad can basically be assured, because they don't want to be fake, but when they decide to do it, they can die, and of course they are all ordinary experiences. Personal opinion: Whether it is good or bad, you must pass the machine identification, because this is the most insurance.
In fact, the simplest way to distinguish between new materials and recycled materials is to see if there is a star point on the plastic film against the sun. Usually there is regeneration, and basically there is no new material. Because the color of the recycled material is not the same, the hand feel is different, and there are many impurities, the color is not good, and the original color is relatively small. From the appearance, the recycled plastic has poor gloss, the surface of the particles is dull, the size is not uniform, and the impurities are generally colored or grayish; the new material has good gloss, the surface of the particles is smooth, the size is uniform, and no impurities, most of them Colorless or milky white. The color of the new material is bright and the color of the old material is dim. In addition, if we want to carefully identify, we can distinguish from the following seven aspects:
1, color: Anything that is more transparent than the one that is not transparent, no matter what color.
2, gloss: good gloss is better than no gloss, is the color of the surface of the material.
From the point of view of physical and mechanical properties, the recycled materials are made of waste products. After the wind and sun, the plastic surface has been aged and degraded, and it has been melted and plasticized by many high-temperature processes. Under the action of light, oxygen and high temperature, some polymers When oxidized, the macromolecular chain undergoes chain scission degradation, and the physical and mechanical properties are degraded. The more the number of regenerations, the more the performance is degraded.
3, drawing: (CaC03 more wire drawing is definitely not good, the reinforcement can not pull the wire) After blowing the fire, use the iron object to quickly contact the melt, and then quickly open to see if the wire is formed evenly, It is a good material. After a few times of pulling, the silk is overlapped and pulled apart again to see if it has elasticity. Can it be pulled again and continuously, and it is good to break after breaking or opening a distance. .
4, igniting (view whether the flame color smokes, whether it contains burning from the fire or not burning at all);
5, smell smell (various plastic flavors are different, including flame retardants, etc.);
6, the above can not be confirmed, please use the fire again, in the process of burning quickly black smoke or melt quickly dripping, not good;
7, floating water: As long as there is submerged water, if the above is not sure, or can not decide, then only the test machine.
