Brightest Flashlight In The World 2017

Ultimate Guide to Select the Best and the Brightest Flashlights

So you are looking for one of the best and brightest flashlight right? You have come to the right place and in this guide, we look at some of the most popular flashlights and tried to organize them based on the type of batteries included and the quantity. But before going over these categories, we also need to determine the best light output measurement a flashlight can have and also need to look for a flashlight with all these criteria and also be in a price range that is affordable. When you are planning for camping, trekking or hunting, a flashlight should be a must have item on your travel list and only if the flashlight is bright, it will be of any use to you during your outing. So please read on to zero in on the best and the brightest flashlight.

How Is Brightness Measured?

The ANSI FL1 standards are the guidelines used by the flashlight industry to standardize the measurement of flashlights. The FL1 standards state that the light output can be measured in three different ways namely:

  • Measuring the light output by lumens

  • Measuring the beam distance in meters

  • And measuring the peak beam intensity in candela

The candela helps us know the brightest point of the beam easily and the beam distance makes us understand how far a beam can travel before it reaches 0.25 lux.

But the best and standard measurement is lumens as both the measurements made through beam distance and peak beam density can be altered easily based on the angles and the reflector size etc. having said that, it doesn’t mean that the flashlight carrying the highest lumens will be flashlight that can provide you the brightest light and a flashlight that can throw light to a greater distance. So you need to understand your requirements before buying a flashlight, whether you need a flashlight that provides you a bright light at a shorter distance or flashlights that throw light to a long distance but with some less brightness.

One more thing that needs to be considered before buying a flashlight is the lumens number. It should be the number based on the FL1 standards, the measurement of light coming from the front of the flashlight and not the prescribed lumen number of the LED emitter. This maximum output of lumens from the LED emitter is just a theoretical measurement and not the actual one. No one knows that is prescribed in the flashlight by the manufacturer, so it is better to believe the lumens measurements made from the front of the flashlight.

Types of Flashlights Considered

When it comes to flashlights, there are various light sources used and the most common light source are the LED emitters. Flashlights that were produced in the earlier years used a metal filament that gets heated up to produce light, but when it comes to brightness, they are not so bright like the present day LED emitters. Apart from LED emitters and incandescent lights, HID lights were also used as light source for the flashlights. High Density Discharge (HID) lights have a quartz capsule filled with gas and once electricity comes into contact with the gas, it produces light. But the HID flashlights are too costly and the cheapest HID flashlight that you can find is about $300 and the incandescent is not durable like the LED and HID. So in this article, we only consider the LED flashlights and not the HID or the incandescent ones.

Brightest Flashlight by Battery

Brightest AAA/10440 Flashlight

Flashlights that run on AAA batteries are the most preferred one because the AAA batteries can be easily found in any local store and also very compact in size. It is not recommended to use 10440 batteries in AAA flashlights and most of the manufacturers are also don’t recommend that as the use of 10440 can cause severe damage to your lights. The reason it should not be used is that the 10440 runs at 3.6 volts, while an AAA battery runs at 1.5 volts. But check if your flashlight can work with 10440 and if it can, then certainly your flashlights lumen output will be a lot better. It’s always better to check with your friends or look into some forums to see their experience with the flashlight.

One other thing to consider when you looking for the brightest flashlights is the batteries and we have some recommendation of batteries for you. When it comes to batteries, you can have either rechargeable or non-chargeable batteries. As far as our analysis and based on the recommendations from experts and consumers, the Eneloop AAA ni-MH is one of the most preferred and used rechargeable batteries. But you also need to have a good charger for your batteries and the La Crosse BC-700 is the best suited charger for the Ni-MH kind of batteries. And the Energizer L92 Lithium batteries is the one that is recommended in the non-rechargeable category.

Brightest AA/14500 Flashlight

In the category of double AA or 14500 battery powered flashlights, the Ni-MH batteries are recommended against the 14500 Li-on batteries, as most of the flashlights aren’t manufactured with the size to occupy these Li-on batteries as well. But if you still opt to choose the 14500 batteries in these lights, then it is better to get some advice from friends or through research on the internet, whether it is the best solution. The reason AA batteries were recommended is similar to why AAA batteries were recommended in flashlights of different sizes. The Eneloop AA Ni-MH are best recommended rechargeable AA batteries and the la Crosse BC-700 the best charger for these batteries.

Through all of our research and reviews we have decided that the brightest LED flashlight by Lumens currently is the Thrunite TN36 UT with a class dominating 7300 Lumens. Just because the TN36 UT might be the brightest flashlight ever does not mean that it is the right flashlight for you. The first thing to consider is what you are going to be doing with the light and decide the size that you need. From there you should consider the types of batteries you are willing to work with. In most cases you will get a large jump in output from li-ion batteries as opposed to alkaline or Ni-MH. Please take these considerations into account before purchasing a flashlight, we want you to be happy with your purchase.
