With the advent of outdoor adventure sports as well as game hunting, the market for High power led flashlight has opened its doors wide. In addition, High power led flashlights are increasingly being used for security and other tactical requirements. There is a widening of gizmo aficionados flaunting their high-end High power led flashlights. Apart from them, most backpackers, first responders, as well as home owners now keep a reliable high power flashlights. Game hunters use High power led flashlights that can be affixed over the rifle telescope to locate targets at long distances through the telescope after sunset. Weapon mounted flashlights have become a specialized section that caters to the light needs for pistols as well as long-range rifles. Additionally, LED market stands to become a $25 billion market by the year 2025. Many small and big companies have taken the plunge into this sector and made investments to reap the benefits of what will become the most promising lighting system of the future. As of now, LED lights have replaced incandescent as well as, fluorescent lights in most of the happening places across the world.
The power of LED lights is described in lumens. One of the highest LED flashlights available claims to shine with 16.000 lumens in turbo mode. Whereas, new keychain flashlight produces 300 lumens, the highest light mode. X-LED, custom-built the most powerful portable lights in the world, up to 100000 lumens. There are numerous companies that manufacture High power led flashlights between these two range and come at prices as low as $30 and above. These flashlights are made of ultra-tough components such as polycarbonate/ABS, which makes these flashlights extremely durable, and it can withstand drops of up to 3 meters onto concrete.
Many factors judge the capacity of a High power LED flashlights.
- Material of the Body
- Lumens or millicandela
- Angle of Viewing
- Run time
- Distance of the Beam
- Resistance to Water
- Type of the Battery
- LEDs life
Unlike conventional flashlights, LED technology is still evolving. Hence, newer technological advances and ideas are being incorporated into LED flashlight technology, so much so that the current illumination capacity, as well as, beam distance are being challenged by the day. High power LED flashlights provide greater intensity, brightness, and longevity as compared to conventional flashlights with incandescent bulbs. An LED bulb lasts almost a lifetime. Whereas, the battery life of LEDs are almost 20 times longer, which saves your money on both bulbs and batteries.
The capacity of High power LED flashlights are enhanced by coating the lens with special materials that reduce reflective loss. In addition to that, precision reflectors ensures that the beam is focused accurately. The reflector ensures that there is hardly any scatter. Every light ray emitted is effectively focused on the intended target without scattering. The same flashlight can deploy multiple LEDs intended for different uses. Thus, increasing run time by reducing the wastage.
Moreover, these flashlights have electronic circuits and are regulated by microprocessors, which provide consistent light beam and longer run time.
These flashlights are meant to be sturdy and are made by machining from aerospace-grade aluminum alloy. Then, it undergoes the hard coat anodized for durability. The LED holder or headlamp, as well as, battery cap are sealed tightly using special O-rings to provide water resistance, as well as, protection to the circuitry from the moisture. The quality and technological advancement of these rings determine the pressure, the flashlights can withstand underwater. Hence, determining its efficiency and resistance capacity to the water.
Since, these flashlights are used for adventure sports along with that for security and rescue operations; there is a need for extra strong grip. The surface of the most High power LED flashlights are fully knurled to aid in getting a good grip and prevent accidental falling or dropping of the flashlights from the hand.
R&D to increase efficacy
On the other hand, more and more investment is being conducted for R&D of making energy-efficient circuit drivers. Innovative ideas have helped reduce power consumption as well as delivering more lumens per watt. Serious research is still being conducted and we are witnessing the upper limits breaching new heights every now and then. Drivers are computer chips that regulate the power from the battery to the LED. These drivers can be pre-programmed as well as user-programmed to suit the requirements of the user along with the self-control thermal levels. Having higher thermal levels for a long time, affects the performance and stability of the driver along with the LED. Having higher temperatures, therefore, influences the longevity of the LEDs. In addition to that, technology incorporated in drivers have thermal controls. Therefore, prevent any chance of over heating and burning.
Reflectors and optics
Another most important component of the flashlight is the technology of reflectors. Reflectors and optics are components that throw out flood, the light coming from the LED to the focused spot. LED is ineffective without a good reflector. Optic technology projects the light further in distance than reflectors, but has a beam that has tunnel vision with no flood light. Optics are easy and cheap compared to reflectors. Reflectors involve a lot of engineering and manufacturing ability. Reflectors are made up of precision machining aluminum and polished. Further, which is coated with a silver PVD. A final reflective coat is given to protect the silver coat.
Power utilization can be managed by using appropriate mode of lighting. Some flashlights while switching on, deliver 100% with one push of the button. Switches off with the next push of the button. However, in some models it is possible to control the output. Further, by holding the push on the button for 1 second to deliver at 50% and holding of the push on the button for 1 second to deliver at 10%. These options prove very advantageous, especially when the flashlight is being used for search and rescue or first responder type of uses.
Hence, High power LED Flashlights are taking over other power sources, due to its efficiency and longevity.
