We are facing numbers of flashlights in the market, which makes us confused and dizzy. So that we usually don’t know which light is best for us. Maybe after reading this article , we can find an answer.
Before you prepare to buy a lighting tool , you must ask yourself : “I use it to do what? ” Of course I do not expect you to just answer too simple, like” to illuminate the dark “. I mean, you use it to work as like working light or camping light , diving light, rescue, cave exploration , or general household and so on . If your flashlight is just for general household, to choose the D -size alkaline batteries incandescent flashlight is better , because when you don’t use it, you can simply put it aside. So that the weight is not the main factor you have to consider.
Sometimes you must take the material of the barrel into consideration . Generally , there are two materials for flashlight: aluminum mixed plastics and polymers. There are several lamps can be used to manufacture the flashlights on the market. Generally they fall into three categories: the incandescent type , LED ( light emitting diode) and fluorescent type .
If you need a flashlight , which must have a moderate brightness and a long running time, you can consider to use a 5 mm LED as light source. And do not forget LED fell to the ground can not be damaged , it is more durable. The biggest shortcoming of 3 mm and 5 mm LED are that they are not easily to converge the light to a beautiful beam spot , so they are only suitable to use at a close distance , not suitable for illuminating objects in far distance . The flashlights of TANK007 adopt the CREE LED lamp, which under the help of the special optical lens or reflector, the converge can match with the flashlights which adopt the incandescent bulb. Meanwhile they have the advantages of long life and anti-shocking.
