I don't have to tell you why flashlights are important. Pretty sure you already understand what they do. However, there are a lot of different features they can have, so I'm going to explain all the features for one brand: LED Lenser. Here goes. Advanced focus system Most flashlights have either a lens or a reflector. A lens gives a homogenous light pattern, but it dissipates substantially when focusing at a distance. Reflectors are good for distances but create rings and holes in the light pattern up close. To get the best focus up-close and at a distance, LED Lenser has created the patented Advanced Focus System. It combines a lens and a reflector so it does both jobs. And since it's patented, LED Lenser flashlights are the only ones on the market that have this feature. Modular system The modular system lets you repair or replace individual parts of your flashlight so you don't have to throw away the whole device. There are also fewer electrical contact points, meaning fewer opportunities for electrical failure. Smart light technology With Smart Light Technology, you can switch between constant power and energy saving modes easily and can even set three different programs: everyday, professional, and defense. Some options are a defense strobe, morse code, and an SOS signal. This one is pretty involved, so you may just want to check out LED Lenser's explanation to see all its characteristics.
