Action Camera Flashlights FAQ

Few Final Words 

Intro To Action Camera Flashlights

Action cameras have relatively small lenses, and their light collection ability is questionable until the first low-light and especially night video capture. After that, their light collection ability is not questionable anymore - it is poor, producing videos of low quality.

Most photo cameras come with a flash, allowing them to create images of good quality even in low-light conditions and even at night.

However, action cameras require continuous light sources - the simplest solutions are portable LED flashlights optimized for use as action camera flashlights.

When looking for a good action camera flashlight, there are a few important things to look for:

Compatibility/Type of Mounts

Flashlights are mounted either directly on the action camera or on the mount connected with the action camera.

There are several typical mounts in use today, some are used by a single type of action camera, while others are a general type of mounts.

Also, some flashlights feature several mounts, for example, one on the top, and two on the sides, allowing the users to mount more than one flashlight or to mount one flashlight in the most preferred way.

Dimensions and Weight

Action camera flashlights are relatively lightweight devices, but they often feature larger front surfaces, potentially causing larger drag when diving and during strong winds (or driving fast on a bike, for example).

Action camera flashlights are compact enough to be easily carried around in backpacks, for example. However, some flashlights may include additional equipment, including additional batteries, battery chargers, mini tripods, stabilizer trays, telescopic poles, and similar.

So, while action camera flashlights are relatively small and lightweight, additional gear can be quite large.

Color Temperature/Color Filters

Light temperature is very important for capturing videos with bright, vivid colors.

Underwater photography and video footage depend very much on the proper light color - the greater the distance, the more red and yellow are absorbed, for example.

LED flashlights with very high CRI (Color Rendering Index), for example,≥95%, help the user take night and low-light videos with colors very similar to those from videos taken during the natural sunlight.

Variable color temperature allows the user to emphasize certain colors in different situations - this can be achieved when the flashlight features variable light color temperature or by using various light color filters.

Most action camera flashlights have many LEDs to avoid having just one strong light source - such a light source would cause sharp shadows combined with video depth and other issues.

Many LEDs and various light diffusers make the light as natural as possible.

Lumens/Light Modes

The more lumens the flashlight has, the more light it can produce.

Most action camera flashlights feature either several light modes with different beam strengths, or the light can be adjusted continuously within a certain range.

Dimming the light also prolongs the flashlight's runtime on a single battery charge and reduces generated heat.

Since some models are not designed only as action camera flashlights, they also come with other light modes, such as SOS light mode and similar ones.

Charging/Power Input

Some flashlights feature USB charging ports, while some come with removable batteries, allowing the user to charge one battery while the second one is in the action camera.

Removable batteries may be custom designed for each flashlight model, or they can be "classic" high-power rechargeable 18650, 21700, 26650, CR123A, and similar batteries.

Battery Life

Battery runtime on a single charge depends on the low-light conditions - the more lumens the flashlight provides, the shorter the runtime. On the other hand, the more light lenses capture, the better quality of the taken video.

In order to prolong the battery runtime, decrease the light strength, but be careful about the video quality - too weak light and the video will be very grainy, to say the least.

IPX Protection Level

IPX protection tells how waterproof the flashlight is. Some flashlights are very sensitive to water, while some are designed for underwater use, down to 50-100 meters, some even more.

However, while having a fully waterproof flashlight is great, some diving flashlights have cooling issues when used outside of the water at full power for a prolonged period.
