Batteries used in the A1
The lithium-ion batteries used in A1 are the 21700 Wuben ABD4800. They have a capacity of 4800 mAh each and a combined capacity of 33600 mAh! They also have three key safety features:
A PCB (Printed Circuit Board) which protects over charge and over discharge, short/over current and high temperatures.
A PTC (Positive Temperature Switch) which is a small round disc at the top of the battery, inside the casing and protects against overheating. They have low resistance, but if there is a surge in current, the battery will heat up and the PTC will increase its resistance to prevent burning.
A CID (Current Interrupt Device): This will disable the cell permanently if the pressure is too high in the cell which can happen from overcharging. If the battery becomes overcharged, its pressure increases, but the CID will interrupt the connection with the positive terminal by venting gas through the hole in the top of the battery.
The LEDs used in the A1
These are 4 Luminus SBT-90 White Big Chip LEDs and offer maximum light output and efficacy which allows them to replace arrays of lower powered LEDs.
SBT-90 LEDs are 'Chip Scale Package' (CSP) chips made with the 'photonic lattice' technology of Luminus. This enables large area LED chips with uniform brightness over the entire LED chip surface. The optical power and brightness produced by these large monolithic chips enable replacement of arc and halogen lamps where arrays of traditional high powered LEDs cannot.
The SBT-90 series has the lowest thermal resistance of any LED on the market. This means that the LEDs can be driven at higher current densities whilst maintaining a low junction temperature and results in increased brightness solutions and longer lifetimes. The reduction of thermal resistance results in fewer failure points from heat along with increased reliability
How does the A1's reflector help it achieve so much throw?
By itself, an LED or light bulb emits light in all directions - this is useful in some cases (for example, if you want to create ambient lighting in a small area), but to make a well defined light beam in a single direction, the light source needs to be 'collimated'.
Collimating is the scientific term which means making light beams parallel. In the Wuben A1, the light from the powerful SBT-90 LEDs are reflected around the surface of the reflector and collimated in such a way that the rays of light run parallel to each other in the middle of the reflector.
These are three main factors that influence the A1 reflector’s ability to achieve 2000m throw:
Reflector shape: Long throw flashlights have the same general shape. This is because they use the 'parabolic' effect. The parabolic effect also enhances recording equipment, telescopes and satellites. The A1 uses an elongated, parabola-shaped reflector, which collimates the LED light in an effective way. This creates a focused beam spot which is an important feature of a long range flashlight.
Reflector diameter: Large throw distance flashlights need large size, depth and diameter reflectors like the one of the A1.
Reflector texture: The A1 has achieves its large throw distances by using a smooth, highly polished reflector.
Advantages of using the A1
Having a throw of 2km, the A1 has a serious 'cool factor' but can it really be useful? Well there are some specific situations where the A1 is a necessity.
Search and rescue: The A1 will be very helpful for search and rescue situations and allows you to light up long distances and cover ground more effectively and at the same time, the beam may serve as a beacon to the person you’re searching for.
Law enforcement: The A1's ability to inspect a situation while keeping your distance cannot be overstated. The hot spot of the A1 is what you need to quickly identify potential threats, investigate unfamiliar sounds or commanding a suspect’s attention.
Emergency signalling: If you’re ever in a position where you need to use your A1 as an emergency beacon, you’ll appreciate the longer throw distance which will increase your likelihood of being found. In an emergency such as being rescued from a flooded building or having an injury deep in a forest, the A1 makes an incredibly effective signalling tool especially with its SOS mode.
Land management: The A1 will let you search and inspect over greater distances, so you don’t have to get up close to investigate intruders, missing livestock, and other issues that arise in the dark. Ranchers, farmers, and those who live out in the country are likely understand the importance of having a long throw flashlight that covers larger distances.
Increased battery life: The 8 21700 A1 batteries have a capacity of 33600 mAh! This large battery source also increases runtimes so you have to replace and charge batteries less often.
Mobility: The A1 delivers more than most vehicle-mounted spotlights can will put this power in the palm of your hand and go where no vehicle can go. It is an invaluable tool for security, search and rescue and law enforcement.
How does the A1 prevent overheating?
Materials: The A1 is mainly made from aluminium alloy which is a superior heat conductor and allows the heat to freely escape more than other metals with the same hardness. Aluminium also has low weight density which reduces the overall weight of the flashlight making it easier to hold and carry over long distance.
Fins: The A1 has ridges on the head of the light which increase the surface area of the aluminium alloy. As this material very good at dissipating heat, increasing the surface area of it will help dissipate even more heat. Extended ridges on the A1 transfers heat away from the circuitry making it more reliable.
Step-down setting: The A1 stays on turbo mode for 2 minutes at 20,000 lumens, then reduces to 6,000 lumens for 2 hours. The reason for this is to prevent overheating which could potentially start a fire.
Head size: The A1's large diameter head not only helps focus the beam, but acts as a heat-sink to prevent over-heating!
