This is just a generalization of some of the different kinds, styles and colors of flashlights and lanterns. Be careful when choosing a flashlight or a lantern. You want the best one for the job. For example, if it is going to be used for underwater use, make sure it is actually made for that reason. If the need is for emergencies, and you want it ready to go if there is an emergency, then probably the one you will want is a rechargeable flashlight. There is literally hundreds of many flashlights and different uses for them. Just make sure you get the right one that suits your needs.
The LED light is a great replacement for the old incandescent light bulb. Led flashlights are much easier on batteries, and are much brighter than the incandescent flashlights. Manufacturers are making more universal flashlights and lanterns. They have two or three different lights in one, or a flashlight and a lantern in one. They tend to be a little more large and not as user friendly because of the extra parts needed, but they still are very efficient and get the light you need.
There is also a great selection of colors available. Colors that are made for construction so they are reflective and more noticeable. The last flashlights that I wanted to mention are the ones that are heavy duty and made specifically for rough and tough use. These would be the ones that get used at construction sites, mining and recreational use.
Now, on to the lanterns, the really nice thing about the lanterns that are manufactured these days are all the ways that they are powered. They even make rechargeable, fluorescent and LED. The lanterns are much more safe than they were a number of years ago, because of there gas free so they are not so flammable. The fluorescent lantern is really an improvement for lanterns and in some cases trouble light lanterns for the simple reason they are much better that they do not draw so much power from your power source. The bulbs outlast any other form of light bulbs. That is the one thing that makes the lanterns much better now.
So, as you can see, there is almost no limit to purchasing the best flashlights and lanterns available.
