There are many benefits for an LED flashlight and here are two of the biggest: Economical and Longevity.   The biggest benefit of an LED flashlight is that you won’t have to change the batteries and light bulbs as often. Flashlights with incandescent bulbs last for only a few hours, maybe 20 illumination hours total, where an LED flashlight could last hundreds of illumination hours. That means big savings on batteries.  In addition to not having to replace batteries, an LED light bulb last longer than regular incandescent bulbs. I think we’ve all been in a situation where a bulb goes out right when you need light the most, and changing the light bulb in the dark is difficult, if not impossible. In the past, incandescent light bulbs would last about 20 hours  but LED light bulbs will last hundreds maybe thousands of hours. This means even “MORE” savings for you over time.  An LED flashlight is also a great buy because it is more resilient. Most LED lights nowadays come encased in aluminum making it water resistant or waterproof, allowing more usability for the outdoors. I have a small Fenix PD10 and it’s been with me on fishing, camping, and hiking trips. Never once – even with all the dirt, smoke, and rain – did it fail. That little guy has been good to me.  Another thing to mention is the resilience of an LED bulb. If you drop a flashlight with an incandescent bulb you run the risk of breaking it’s filament – the part of an bulb that emits light. The LED bulb has a compact light source which are small reflectors or lenses, and this makes them less apt to break.
