best LED flashlight<\/a>, here are a few points, for reference:<\/p>\n1, look at the light source, generally\u00a0LED\u2019s\u00a0life is\u00a0one hundred thousand hours, and beam\u00a0distance is very far. Particularly with slow light decay\u00a0and optimized\u00a0design of the\u00a0circuit.<\/p>\n
2, look at the welding and sealing,\u00a0welding process\u00a0should be excellent.\u00a0Each diode is connected by welding on the circuit board, lack of solder\u00a0or\u00a0cold join\u00a0will caused circuit board broken that is possible to cause flashlight\u00a0does not shine or\u00a0unstable voltage supply.<\/p>\n
3, look at the battery, with the improvement of awareness\u00a0in\u00a0environmental protection, it is\u00a0more and more common with rechargeable\u00a0lithium batteries\u00a0while the ordinary battery easy to leak liquid\u00a0long-term use; rechargeable batteries\u00a0have\u00a0lower\u00a0energy consumption\u00a0and\u00a0longer\u00a0life, more important,it can be recharged\u00a0more than 500 times.<\/p>\n
4, waterproof\u00a0level,\u00a0best\u00a0LED flashlight with excellent waterproof function,in addition with strong impact\u00a0resistant. There is a circuit board in front of the torch, only a little\u00a0water is easy to\u00a0cause\u00a0short circuit, therefore\u00a0good waterproof performance is very important.<\/p>\n
5, light spot. The best\u00a0LED flashlight\u00a0has\u00a0uniform spot.\u00a0Inferior-quality flashlight\u2019s light spot is nonuniform\u00a0and has the astigmatism phenomenon.<\/p>\n
