If you’re looking for a reliable underwater strobe that delivers solid power, fast recycle times, and excellent coverage, the Ikelite DS165 is definitely worth checking out. This strobe replaces the older DS160 and brings some impressive upgrades, taking the best features from Ikelite’s higher-end models and putting them in a versatile, mid-range option.
Power and Performance
The DS165 packs 160 W·s of power, making it a strong performer without being overkill for most dives. It’s slightly less powerful than Ikelite’s top-of-the-line DS230, but still more than enough for everything from wide reef shots to macro subjects. One of the standout features is the 120° beam angle without a diffuser, which gives soft, even coverage while reducing backscatter, a real bonus when you’re aiming for clean, crisp underwater shots.

What’s New Compared to the DS160
Ikelite has upgraded several key elements:
- Updated flash tube for smoother lighting
- Improved glass and beam angle for even coverage
- Slightly cooler color temperature at 5,000K, giving brighter, more natural colors
The combination of these upgrades makes the DS165 feel like a professional-grade strobe in a very versatile package. Reds, oranges, and skin tones look natural, and blues in the background really pop, especially if you shoot in RAW and make small adjustments in post.
Real-World Use
This strobe is incredibly easy to work with underwater. Wide-angle scenes, reef setups, and even fast-moving marine life are all covered thanks to the generous beam. The light is soft and even, so you rarely have to fuss with angles, and you get less backscatter when shooting without a diffuser. Macro shots also benefit from the smooth, circular flash that highlights details beautifully.
Batteries and Recycle Times
The DS165 uses a nickel-metal hydride battery pack, which is travel-friendly and very robust. These strobes can take a beating waves and currents without issues. Recycle times are fast: about 1 second at full power, and even faster at lower outputs. You can comfortably get hundreds of shots on a single charge, making it easy to dive all day without worrying about running out of power.
Controls and Usability
Ikelite has kept things simple:
- Easy-to-use power dial, updated from the DS160
- Battery life indicator so you always know your status
- Handy aiming light (great for macro or as a backup night dive light)
Triggering is done via an electronic sync cord, which works well with TTL setups. There’s also an RC (fiber optic) version for different triggering preferences. Depth rating is 100 meters, more than sufficient for most recreational dives.
Alternative Options
The RC165 Strobe has all the same features as the DS165, except the electrical is replaced with an integrated fiber optic TTL port.
The DS230 Strobe is 33% brighter with the same form factor for serious wide angle shooters and photographers who need maximum light output.
The DS232 Strobe is 33% and includes a built-in 2500 lumen video light for hybrid shooters.
Bottom Line

The DS165 is a reliable, versatile strobe that balances power, coverage, and usability. It’s great for wide-angle, macro, or high-speed action dives, with consistent output and beautiful color reproduction. If you want a professional-grade strobe that just works and adapts to a wide range of shooting conditions, this one is worth considering.
