lithium coin battery What you need to know about LED flashlight
Everyone living in this contemporary society benefits from LED flashlights.LED flashlights are available for camping, hiking and other outdoor activities.On the one hand, LED flashlight brings huge benefits and convenience to consumers.On the other hand, more sellers have successfully profited from the LED flashlight business and are trying to make more money over the next decade.But you still need to know something about the LED flashlight.First of all, you need to pay enough attention to the battery type and battery life of the LED flashlight.It is generally believed that LED flashlights are more efficient than traditional incandescent flashlights.While the LED flashlight is an energy sourceThis does not mean that the LED flashlight has a very long battery life.In fact, the battery life of a specific LED flashlight is affected by many factors, including battery type, number of LEDs, amount of light emitted, rated power, etc.In general, there are two kinds of batteries: alkaline batteries and lithium batteries.Compared with alkaline batteries, lithium batteries are more expensive, but have a longer life and better performance at low temperatures.Of course, in addition to the battery type, other factors have a great impact on the battery life of the LED flashlight.Secondly, you need to know the lumens and pay great attention to the lumens of the LED flashlight.We know that light is usually measured by a special unit of measurement of lumens.But lumens only tell us a small part of the truth, because lumens are measured at the center of the beam.Therefore, it is easy to understand why two different LED flashlights with the same lumen show very different results.You may find that a keychain flashlight with an LED will give a very bright light to the center of the beam, but at the edge of the light will soon disappear the LED flashlight with several LEDs may send the same amount of light to the center of the beam, but it will still send a fairly bright light to the outer ring of the light.In other words, the two LED flashlights have the same lumens, but one may emit more light than the other.Therefore, you don't need to take the lumens of the LED flashlight seriously, because lumens won't tell you how much light it will emit in total.Finally, you need to make enough emphasis on the effective projection distance of the LED flashlight.The LED flashlight is like the coin has two sides and has some disadvantages.One of the biggest drawbacks of the LED flashlight is that it can't throw light like an incandescent flashlight.However, most consumers are not annoyed with this factor because most of them use LED flashlights to see what is relatively close to them.Of course, if you are particularly picky about the effective projection distance, you need to pay attention to it when you are ready to choose an LED flashlight.
