Red LED Flashlight Buying Guide: What to Look for in a Red Lens Flashlight for Night Vision, Hunting and Tactical Uses

We all know flashlights are useful – truth be told, there are times our survival depends on them. It is often assumed that the brighter a flashlight is, the better. That’s not always true, at least in certain situations. There are times when a red flashlight is more suitable than the regular white ones. Regular flashlights are brighter and cover much more ground, but there are cases in which the white light is brighter than needed. For night vision in an enclosed area, a red flashlight is ideal, as it does not cause our pupils to shrink like the white one does. That way, we can take in more light and see clearly.

Some red flashlights are designed for applications in astronomy, to read charts, for example. So, you often find astronomers carrying them along with their telescopes. Red light flashlights are also useful to hunters who camp out all night. A red light is less likely to startle that deer you’ve been patiently waiting for in your hunting blind.

The best red light flashlights use energy-efficient LEDs and have tough and durable shells that can endure rigorous use. They are lightweight and well equipped for mobility. Red flashlights have varying brightness, just as they come in varying shapes and sizes. They are usually designed so that you can easily switch between the red, white, or other color lights as the case may be. You will get the best out of a red flashlight if you choose the appropriate one, which you will with our help as you read on.

One more quick thing, when we are talking about red light for night vision, we are not talking about infrared flashlights for night vision. Those don't use red light, but rather emit infrared light which is not seen by bare eyes.

Anyone who has been disappointed by their flashlight when they needed it the most knows how important it is to get a dependable one. As such, you want to entirely do away with the cheap red light flashlights and their empty promises.

Fortunately, with as little as $10, you can get a good red light flashlight that will help you achieve what you need it for.

If you want a variant with great features, or perhaps one that is multifunctional, you have to be willing to pay close to $60. The number of features, the materials used, and the technology involved are usually the factors that determine the pricing of a red light flashlight. There are also military grade tactical red LED flashlights that can cost hundreds of dollars.

Another thing that will impact the price of a red lens flashlight or red LED flashlight is whether it comes with other color options as well, such as blue and green. If you only need the red and regular light, you can save money by shopping for a flashlight with fewer color functions.

You’re here reading; this means you want a red light flashlight for reasons best known to you. Since you know why you want it, you know what to expect from it. In that case, pay attention to the following features:
  • Type
  • Beam Distance
  • Lumens
  • Battery Type
  • Runtime
  • Material
  • Dimensions
Further explanation below will help you understand how these features affect the performance of red light flashlights.
Construction and Design
The red flashlights covered in this review are all LED because its rating is unparalleled in energy, efficiency, brightness, and duration, among other things. Less expensive, dare we say cheap red light flashlights, will often have a regular flashlight bulb with a colored red lens that can be added. This is different from LED lights with interchangeable colored lens because the LED light is much brighter. So be careful, just because the light comes out right, doesn't mean it will be effective for night vision.

Multipurpose products are cost effective and highly sought after, and it makes a lot of sense if one thing can serve many purposes. It is with this mindset that manufacturers design red flashlights. It is rare to find a full-fledged flashlight just in red. Most are regular flashlights that can be switched to red light; the way this happens is where brand creativity comes in. Some flashlights are dual color with both white and red LEDs and separate buttons to turn them on. Others are designed such that the flashlight has white LEDs, but you can convert the white light to red when you need it with a filter cap. It is not uncommon to find flashlights with blue, red, green, and white, all in one.

The battery types a red flashlight uses is totally at the discretion of the manufacturer. The common types, though, are the AA and AAA types. Some flashlights even use built-in rechargeable batteries; those are often the multifunctional types. We have seen red flashlights that use 18650 batteries. One awesome type we came across is one that can use either a single 18650 battery or three AAA batteries. How cool is that!? Whether you use rechargeable or disposable batteries is up to you. Since we all know the advantages of using rechargeable batteries, we’ll leave that decision to you.

Flashlights these days use LED bulbs and we all know how long lasting and energy efficient those things are. This singular factor has tremendously changed the runtime of flashlights. How long a flashlight will beam bright now mostly rests on the capacity of the battery used. An average red flashlight will stay on for hours on end, running on fresh batteries, usually outlasting what you need them for. Of course, there are some flashlights that have found a way of making their flashlights run several hours without needing a battery change.

You will often see flashlights being described as tactical – that’s another way of saying it is cool and useful. Flashlights are supposed to be tough, rugged, and ready to rumble. They are one of the most important items in a survival toolbox, so they should at least be able to survive. To ensure that, they are often made with tough materials that won’t easily succumb to hardship. A lot of them have aerospace-grade, anodized aluminum shells, which are rugged, yet lightweight. You don’t want a flashlight that should help you survive adding to the weight you have to carry. They are often compact, making them easy to carry around. In most cases, you won’t even notice their weight.

Performance and Ease of Use
Red flashlights are not usually as bright as the white ones, for obvious reasons, but they still have to be bright enough. Red flashlights are uniquely useful in the sense that they don’t make our pupils contract like the white ones do. This causes less stress on our eyes and we get to take in more light, hence, see more clearly. The brightness of of a red flashlight is a function of the LED used and is measured in lumens. The higher the lumen rating, the brighter the flashlight. Red lights often have lumen ratings between 100 to 200, but you might find some with more or less. So, just be on the lookout for what suits you most.

Beam distance is another thing to consider. Ideally, the brighter a flashlight, the more distance it will cover. Some red flashlights cover close to 100 meters. What is important here is your need. So, what you should go for is what will fulfill that need. The best way to go about your decision is to clarify what you need first and let that guide the choice you will make.

Do keep in mind that no matter how bright your red LED flashlight is, your ability to see in a distance is still limited by your own eyesight. If you need to be able to things that are far away clearly, you will probably need to pick up a pair of night vision goggles or binoculars.
