LED lanterns for outdoor use
If there's an invention that has truly revolutionized the field of outdoor lighting, it has to be the LED lamp. The invention of light-emitting diodes has made it possible to build headlamps, flashlights, and camping lanterns that save a lot of energy. Saved energy means fewer rechargeable batteries, which means less weight in your backpack and fewer disposable batteries to toss. This makes the LED lamp a clear asset when it comes to environmental sustainability. This point is particularly important to outdoor athletes. That includes mountaineers, trekkers, climbers, and hikers. Environmental sustainability is an issue that always comes up in outdoor circles.
What is an LED lamp?
An LED lamp doesn't use conventional incandescent bulbs, but rather LEDs, hence the name. Incandescent bulbs require a lot of electricity, making them very inefficient. A large fraction of energy is wasted in the form of heat. Until a few years ago, headlamps with various types of bulbs (halogen lamps) were still used in outdoor sports. These systems had high energy requirements. Most of them were bulky, especially the brighter models. These classic headlamps were heavy and distracting during almost all activities.
The advent of LED lamps made it possible to build compact, energy-efficient headlamps with high luminosity. Since the end of the 1990s, LEDs have improved greatly in terms of luminosity. LED is an abbreviation for "light-emitting diode".
Advantages of LED lanterns
LED headlamps have a wide range of practical advantages over their predecessors. LED technology saves energy, making it more environmentally friendly. As mentioned above, this reduces the weight of your needed tour supplies. You'll use fewer rechargeable batteries and polluting disposable batteries. Most LED lanterns can also be dimmed. This is easier to implement with LED technology than with conventional technologies. LED lamps have a long operational lifespan. In other words, you don't have to carry any replacement bulbs with you. Furthermore, old LEDs don't burn out completely. They gradually dim as they age.
LED lanterns can be made in all sorts of colors using various semiconductor materials. So it's very easy to make LED headlamps with red light (for improved night vision). LEDs aren't very sensitive to frequent switching. This makes it easy to implement flashing modes without damaging the bulbs.
The everyday uses of LED lanterns
Here's an example that best illustrates the potential luminosity of LED lanterns. Since 2011, Innsbruck Airport has used LED technology to light its airport ramp. Modern traffic lights are a testament to the long product life and high energy efficiency of LEDs. The benefits shown in their everyday uses are perfect for the backcountry, too. LED headlamps have a variety of designs. There are simple lamps for nighttime hikes and camping. Then there are extremely bright headlights for trail running and mountain biking. Finally, there are indestructible LED lamps for mountaineers. Lamps vary in size, weight, and lighting modes. They also differ in power sources, which include rechargeable batteries at the front or back of the head, in a backpack pocket, or on your hip belt. The price obviously varies, too. As always, you should consider the intended purpose in order to find the perfect lamp model.
