LED flashlight is a new type of flashlight. Because the LED with high brightness, low power consumption, long life, small size and other characteristics, it is ideal for portable lighting. LED Flashlight has many advantages.
LED has a long life, generally up to 50,000 hours or more life than conventional incandescent light 5 to 10 times higher. It features cold light, low heat, and high safety without damaging the lamp. There is fast response, high impact resistance, and small size, easy compact and lightweight so on. Saving, energy saving, new environmental light bulbs. Fast response if 1us, no warm lights can improve safety.
Household generally not more than 12 use the LED flashlight battery in the 2 to 3 as well, and then a little big waves, can be used for other special needs identified according to their needs. Of course, high power LED flashlights generally can not reach the number 12. Each diode is connected to the circuit board by soldering, and if there is a bad contact Weld, it may cause bulb does not light or affecting the overall usefulness. Ordinary batteries and lithium batteries have two kinds, although a rechargeable lithium LED flashlight battery, but life is low, about 2 years, LED life span of about 10 years, according to the actual situation to choose. Good LED flashlight, high brightness, slow decay. Lamp out of the situation, it is difficult to visually distinguish it from the bad, and can look at the case of light bulbs consistency.
Good LED flashlight with waterproof function, good seismic performance, the ruggedness. Since it is electronic, the front of the flashlight has a circuit board, once the water prone to short circuit, causing damage. Good LED flashlight aperture uniform a circle, and poor LED flashlight beam is divided into uneven distribution of yellow and blue. Condensing surfaces bulb try to focus on that. This flashlight unlike ordinary flashlight can adjust the focus, purchase should be careful not to have astigmatism.
