A good underwater strobe is the key to getting proper lighting and color in underwater images. When you try taking photos underwater without a strobe, they look washed out and blue. Light and color loss start just a few feet underwater due to a natural phenomenon called light attenuation. Underwater strobe lights add white light back into your image and bring out the true colors of your subjects, allowing your photos to pop. In fact, almost every underwater photographer shoots with a strobe to illuminate the astounding rainbow of subjects beneath the seas.

Pick an underwater strobe based on your style of photography, looking at important features such as power (listed as Guide Number), beam angle, and recycle speed. If you typically shoot wide angle underwater photography, then you might want to look at more powerful strobes with wider beams. Macro photographers can get by with less powerful strobes. If you shoot quick subjects that move fast, then look for a strobe with a fast recycle time, like the Sea & Sea YS-D3II/YS-D3 Duo or the Ikelite DS 160 II. Remember to think about other options and accessories such as diffiusers, strobe size/weight and the type of batteries required. Some strobes are compatible with TTL or TTL converters and some are not. TTL allows you to shoot "automatically" with your strobes, and allows your strobes to "choose" the correct power output for your scene. Some TTL works better than others, so it's important to know your option. To learn more about strobe triggering options, read this guide on how to fire your strobes underwater.

This guide will help you pick the best underwater strobe light the first time so you can avoid the headache and cost of outgrowing a strobe or needing to upgrade when you buy a new camera!

The Sea & Sea YS-D3 "Lightning" is one of the world's best strobes for underwater photography. The "Lightning" in its name is well deserved. The YS-D3 is one of the fastest strobes on the market. At half power, it has a recylce time of a mere 0.6 seconds and below a quarter power, there is virtually no recycle time! It has lots on improvements from its predecessor, the YS-D2J. This strobe has a high power, professional-grade beam with a max guide number of 33 (on land). The flash tube features an aspherical troidal lens which produces even light dispersion. The strobe is slightly cooler than the YS-D2J, with a nice color temp of 5800K. The YS-D3 has a wide variety of native accessories from snoots to slave prisms. We recommend the YS-D3 as a future proof strobe that is especially effective for photographers shooting quick subjects.

The Sea & Sea YS-D3 Duo delivers a very similar performance to the YS-D3 II, but has the optional RC-Mode which is not found in the YS-D3 II.

There are two options available:

1. Ikelite DS 232 with Video Light - $1495 (See below under "Best "All-in-One" Combo options)
2. Ikelite DS 230 with Modeling Light - $1295

As the latest addition to Ikelite's DS Strobe line, the Ikelite DS230 is 33% (213W) more powerful than its siblings. The controls are larger and taller for easier control, even while wearing thick gloves. Click-stops at each power setting and a limited sweep allow you to quickly jump between TTL, full power and the lowest manual power setting without taking your eyes off your subject. The DS230 also uses new circuitry which makes the recycle time ultra fast! A new circular xenon flashtube produces a perfectly gradated beam pattern and warm color temperature. Another awesome feature of the strobe is that it has an integrated 2500-lumen video light. It also has a sensor which automatically shuts off when taking a photo. You can also use older batteries (for the DS 160 and 161) with the new DS 230 strobe.

Both the Ikelite DS230 and the Ikelite DS232 have the same strobe capabilities, with the only difference being with the video light vs modelling lights options. The Ikelite DS230 has a 205 Lumen LED Spot light, while the Ikelite DS232 has a 2500 lumen video light in the center of the ring flash.

We recommend the Ikelite DS 230 and DS 232 to photographers who need the highest quality beam for wide ange photography, compatable with some the best TTL converts (automatic strobe power) from Ikelite on the market.

There are two options available:

1. Ikelite DS 162 with Video Light - $1295
2. Ikelite DS160 II with Modeling Light - $995

The Ikelite DS160 II combines power with wide angle coverage to give you the most bang for your buck. It has been upgraded from the original DS 160 with a quicker recycle time of .1 to 1 seconds, better ergonomics, and 300 flashes per charge at full power. The quality of light is exceptional due to a round flash tube and a custom powder-coated reflector designed specifically to deliver the softest, most even coverage possible. Strobes with a straight flashtube may be capable of high powers, but require the addition of a diffuser to spread out their sharp, rectangular beam pattern and reduce harsh hot spots. The DS160 II beam is designed to be perfectly soft thanks to its reflector design, and is capable of providing you the coverage and power you want and avoiding the one f/stop loss caused by adding a diffuser.

Both the Ikelite DS160 II and the Ikelite DS162 have the same strobe capabilities, with the only difference being with the video light vs modelling lights options. The Ikelite DS160 II has a 205 Lumen LED Spot light, while the Ikelite DS162 has a 2500 lumen video light in the center of the ring flash.

As one of the more highly featured strobes, we at Bluewater Photo recommend the Seacam Seaflash 160 Underwater Strobe, a component of our Seacam underwater lighting solutions, but it does come at a high price due to it's high end finishes and impressive specifications.

This is a strobe with ergonomic controls and settings that are easy to read and use. A superb product that is incredibly durable and dependable. The strobe does unfortunately suffer from a low GN of 20, which is why it does not rank higher in our recommendations for a wide angle strobe. Also it's higher price than it competitors, which may also count against it.

There are a lot of great strobe options out there for photographers on a budget. However, this is a quick word of warning. Underwater lighting is the most important aspect of underwater photography. We recommend spending as much of your investment as possible in underwater lighting systems. It is better to budget a housing, lens, or camera rather than underwater lighting. If you purchase any of the "professional" grade strobes above, then you will be able to keep your kit "future-proof" and bring your strobes along to any upgrade. Budget strobes tend to be great for compact and macro shooters, but they can be more difficult to move to your next system if you choose to upgrade.
