An LED flashlight is one that uses an LED bulb rather than a traditional incandescent bulb. The reasons for choosing an LED flashlight over a standard flashlight are numerous and include the fact that the bulb is likely to outlive you, that it produces a much higher quality beam than any incandescent bulb can hope to, that it can project that light effectively for hundreds of feet and that it uses only a fraction of the energy required by an incandescent bulb. In 2019 there is really no excuse for not having a rechargeable LED light.\r
