Undoubtedly, one of the most important features about the 900 lumen led flashlight is the 900 lumens themselves. Most of the people, surprisingly, have no idea of what the lumens are used for, and what the 900 lumens actually give information about. In short, lumens is another way for saying what the runtime of a flashlight is i.e. how much time will pass until the flashlight needs to be charged again. Obviously, that means that lumens are used only when a flashlight comes with a charger, but not with 1.5V batteries.
But what is the runtime of a 900 lumen led flashlight? That is a fair question, which can be answered very easily. Basically, 100 lumens are considered as equivalent of 10 minutes of runtime. Thus, a 900 lumen led flashlight has got a runtime of around 90-100 minutes. The same calculation can be made for 1000 lumen flashlights, 500 lumen flashlights etc.
Of course it should be mentioned that the lumen is not the only important technical characteristic though it is the only which is present in the product's name - a 900 lumen led flashlight. Yes, it could be claimed that it is the most important one since people are mainly interested in how much they will be able to use such lasers before another charging is needed. But specifications such as operating temperature (still known as working temperature) and storing temperature are not less important at all. A good and reliable should be able to work at temperatures between -25 degrees (in Celsius) and +55 degrees (again, Celsius). Of course, the wider that range is the more reliable the particular will be.
Obviously, reliability is an important factor when talking about flashlights, no matter if it is a, a 1500 lumen flashlight or a battery-powered flashlight. But reliability is determined by another very important factor: material that has been used for the flashlight's body. One of the most preferred and strongest materials for flashlights, including the , is aluminum. It is extremely strong and light at the same time. That makes flashlights strong, light, portable and compact all at the same time. It sounds pretty good, doesn't it? So in conclusion, there are just a few specifications to be taken into consideration when choosing the 900 lumen led flashlight. But they are really not to be ignored!
Those, however, are just general facts which are interesting but do not give any particular information to a customer. So let's give some more info about the 900 lumen led flashlights.
