2023 Best Underwater Strobes

SeaLife Sea Dragon Universal Flash

The SeaLife Universal Flash is sold as a single unit or paired with the Flex-Connect tray and handle, making it a great flash for compact camera and housing systems. Manual and TTL (automatic) control, plus the quick assembly/disassembly of the arm system make it very simple to use. SeaLife also sells combo kits with dual flashes, a flash and light combo and more.

The Universal Flash is compatible with any camera using fiber optic cables.

Sea & Sea YS-03 Solis

This is a nice strobe if you’re on a lean budget or looking for a simple lighting solution. The YS-03 Solis doesn’t offer manual strobe power control, but it did receive a complete redesign for last year. My opinion is that strobes grow with you and if you really think you’ll get into underwater photography, try to spend the cash on the YS-01 Solis or even the YS-D3 Lightning, as both offer manual control.

Backscatter Mini Flash MF-2

Backscatter Mini Flash 1 with Optical Snoot

I use the MF-1 and Optical Snoot (the earlier version of this great little strobe) – check out my Camera Gear!

Backscatter has many years experience working with underwater photographers and it shows in every detail of the Mini Flash. This compact, lightweight flash is a great choice for small camera systems and all macro photographers, including creative shooters interested in pairing it with the Backscatter Optical Snoot OS-1. The Mini Flash boasts power comparable to others in its class, simple ergonomics for those with bare hands or thick gloves, replaceable batteries to keep you shooting all day, and a powerful LED focus beam that makes using the Optical Snoot very user friendly.

The MF-2 is an updated version of the original flash that includes a much faster recycle time, wireless remote control, high speed sync, lager 21700 battery for more life, and more.

Batteries and charger not included, but you’ll want Backscatter’s high quality batteries for best results.

Sea & Sea YS-01 Solis

This redesigned version of the popular YS-01 strobe features a wide, even 110 degree beam, ability to shoot in manual or automatic (DS TTL II), a modeling light, and refreshed reliable circuitry. This is a fantastic first strobe option.

$490 | Backscatter | Mozaik | Amazon

Ikelite DS51 II

This is a great strobe for Ikelite shooters who want quality, light weight, compact size and the versatility to shoot in TTL or manual modes. There are six manual power settings adjusted with a large dial that is easy to read and adjust.

$495 | Backscatter | Mozaik

Inon D200

Another great Inon strobe, the D200 boasts a much faster recycle time than the lower S2000 model. The strobe is slightly buoyant underwater, which means less float is needed to make your rig neutral. A rotating light shade helps control light and flare, while the phosphorescent back control panel is easy to operate during day or night.

$540 | Backscatter | Mozaik

Kraken KR-S05

The Kraken KR-S05 strobe is small and compact with a guide number of 24, color temp of 5000K and 90-degree beam angle. The strobe uses a rechargeable 14.8V Li-ion battery pack (4x 18650 batteries wrapped to single cell). A digital read out screen on the back shows the current strobe power level and estimated number of flashes remaining.

Kraken products always have a great value to price ratio, and combined with the integrated video light, will be an interesting option for photo and video shooters.

$599 | Backscatter | Mozaik

Sea & Sea YS-D3 Lightning

Sea&Sea’s latest strobe, the YS-D3 Lighting features a redesigned flash tube lens for wide-more even light distribution, lighting-fast recycle time at half power, improved control ergonomics and a complete internal overhaul designed to be more modular (easy to fix in case the user floods the battery compartment). This strobe is sure to find its way into the camera bag of many underwater photographers.

Ikelite DS160 II Strobe

A solid strobe with a lightning-fast recycle time – just 1.0s at full power – Wow! These strobes have a guide number of 24, so if you’re a dedicated wide-angle shooter you might want to look at the new DS230. The extremely accurate TTL (automatic) mode also ensures you bring home the perfect exposure. The strobes are designed for use with sync cords instead of fiber optic cables.

$995 | Backscatter | Mozaik

Retra Flash Prime X

The Retra Flash Prime X is an elegant strobe. A circular flash tube produces high-quality light and very fast recycle times. The flash features a built-in leak detector, intuitive and easy to use control ergonomics, and a bayonet mount compatible with a range of fun accessories. The X model is a newer version of the original Prime, featuring several improvements to the internal circuitry.

For maximum flash power and stronger modeling light, consider the Retra Flash Pro X below.

Retra Flash Pro X

The Ferrari of underwater flash. This flash uses a circular flash tube, creating unparalleled light output and very fast recycle times. Retra works closely with the top underwater photographers to fine-tune every product, and it shows in the elegant design, control ergonomics, and features.

The Retra UWT App allows you to set advanced features and customize the flash for the way you shoot. Add the Supercharger to achieve lightning-fast recycle times (great for fast action sequential shooting). The font bayonet mount is compatible with the LSD Snoot, several different round diffusers, macro reduction ring kits, and reflectors. The X model is a newer version of the original PRO, featuring several improvements to the internal circuitry.

Important Strobe Battery Info

Underwater strobes today are designed for high performance, creating bright light and firing rapid bursts in succession. You’ll get the most from your strobes by using high performance rechargeable batteries – so much in fact that most manufacturers specifically recommend the batteries below.

Note that if you shoot an Ikelite, Kraken or Backscatter strobe you’ll use their proprietary batteries, so this doesn’t really apply to you. It’s important to mention, however, that the Backscatter strobe requires a specific high-quality 21700 (MF-2) or 18650 battery (MF-1), so be sure to follow their recommendations.

Best Underwater Strobe Batteries

Panasonic Eneloop batteries are widely regarded as the best rechargeable AA batteries for your underwater strobes. The regular Eneloop batteries are the most popular, however you’ll get the fastest recycle times and most flash fires with the high-capacity Pro version.

Note also that the batteries do wear out over time, so it’s a good idea to recycle them and replace with new ones every couple years or couple hundred photo dives.

I’ve listed a great 3rd party battery charger below, which I use for all my rechargeable AA and AAA batteries. It soft charges 8 batteries at a time (all independently) and is very affordable compared to alternatives.
