Underwater Strobes Buying Guide

To capture the best images while underwater, an underwater strobe is a must-have in your diving camera gear. They serve as a source of illumination and help compensate for the decreasing light with depth. Whether you need a strobe to serve as lighting to take nice photos, or just as a light source, it is important that you pick the very best.

We have reviewed the best underwater strobes on the market based on their specified features and customer feedback to help you streamline your choices. Now we will take it a step further and outline the factors you should consider when on the market for an underwater strobe before making a purchase.

Battery Life and Recovery Time

One of the most important factors to consider is the battery life of the underwater strobe you are buying. Also measured as the number of strobes per full charge, you want it to be as high as possible. On average, underwater strobes will come with ratings between 100 to as high as 350 strobes per full charge.

The recovery time, also known as the recycle rate measures how long it takes before the strobe can be fired again after an initial flash. The smaller the recovery time, the better as this will allow you to capture more images per time. The standard is 1 to 1.5 seconds, anything more and it may too slow.

Illumination Power and Coverage

You want the underwater strobe to be as bright as possible. Measured in lumens, a brighter strobe will create brighter images with more defined contrast. Your underwater strobe should also come with adjustable focus so you can vary the illumination between diffuse and focused. Diffuse light is great for capturing wider fields of view, while focused light will work great for macro photography.

Camera Compatibility and Triggering Medium

Another important factor to consider is the compatibility with your camera. While most underwater strobes are designed to work with a variety of selected cameras, it never hurts to check for the company specifications.

The triggering medium of your underwater strobe is another important consideration to make. Underwater strobes are fired either using a physical electrical medium or an optical sensor connected to your camera. Electrical triggering offers the advantage of superior accuracy and quick response but adds the need for proper waterproofing.

Optical sensory triggering uses the flash from your camera to fire the underwater strobe. While it is easier to use, the electronic sensor means more load on your battery and hence, shorter battery life.

Size and Weight

Like with any equipment in your diving gear, your underwater strobe should be as compact and lightweight as possible. This is a great quality if you are a traveling diver or underwater photographer for the most portability and minimal weight while you are underwater.
