Hybrid Underwater Strobe + Video Light
Backscatter Hybrid Flash (HF-1)
A powerful ƒ40 underwater strobe and 5,000-lumen video light in one housing, built for photographers who want to shoot serious stills and video without carrying two separate lighting systems.
When diving with a hybrid setup, having equipment that can transition seamlessly between still photography and video is essential. For underwater photographers looking for the best underwater strobe, the Backscatter Hybrid Flash Underwater Strobe & Video Light HF-1 bridges the gap between high-powered flash performance and continuous video lighting. Rather than forcing a compromise between two separate systems, this unit combines a dedicated underwater strobe with a high-lumen video light into a single, travel-friendly housing.
Built with a maximum guide number of ƒ40, the backscatter hybrid flash delivers ample power to cut through high ambient light, brightly lit shallow reefs, and expansive open-water sunballs. To complement its flash capabilities, the Backscatter hf-1 integrates a 5,000-lumen wide-angle video light, alongside spot and red light modes for focus assistance and discreet night diving. This dual setup allows shooters to capture high-definition video clips between still frames without swapping gear on the dive deck.
For modern mirrorless shooters, the Backscatter hf1 incorporates Smart Control Automatic TTL compatibility for Sony, Olympus, and OM System cameras, ensuring accurate exposures when subject distances change rapidly. It is also fully High-Speed Sync (HSS) compatible and engineered for rapid-fire shooting, maintaining recycle speeds capable of keeping pace with continuous high-frame-rate bursts. To tailor the beam for different environments, the system supports a selectable angle of coverage—ranging from 120° bare to 140° with the included flat diffuser and 160° with optional dome diffusers—as well as adjustable color temperature filters to match ambient water color.
In real underwater use, that means you can light a reef or large animal with flash, switch to continuous video illumination, use red light around sensitive subjects, and return to still photography without adding another major light to the rig.
- Best for: serious hybrid photo/video shooters, wide-angle photographers, advanced mirrorless users and divers who want one versatile lighting platform.
- Main advantage: combines a powerful ƒ40 flash with a true 5,000-lumen continuous video light plus spot and red-light modes.
- Compatibility: fiber-optic triggering only; Smart Control TTL is designed for supported Sony, Olympus and OM System configurations.
- Major differentiator: selectable 120°, 140° and 160° coverage plus accessory-controlled 6500K, 5500K and 4500K flash options.
- Tradeoff: its 1.6-second full-power recycle is slower than some dedicated flagship strobes, including the Marelux Apollo III 3.0 and Sea & Sea YS-D130R.
- Important: batteries are not included; two approved high-output 21700 lithium-ion batteries are required.
At a Glance
Backscatter HF-1 Quick Specs
*TTL operation depends on the camera, housing and trigger configuration. Published weight specifications include batteries.
120° to 160° Coverage for Wide-Angle Control
Wide-angle underwater lighting is as much about beam shape as raw power. The HF-1 starts with broad coverage and can be configured for 140° with a flat diffuser or 160° with an optional dome diffuser, helping you cover fisheye scenes without forcing the strobes too close to the lens.
- 120° standard coverage
- 140° coverage with flat diffuser
- 160° coverage with optional dome diffuser
- Useful for reef scenes, wrecks, large animals and close-focus wide angle
A 5,000-Lumen Video Light You Can Actually Use
The video function is what separates the HF-1 from most underwater strobes. Instead of mounting a separate video light beside your strobes, you can switch the same unit between flash, wide continuous light, spot light and red light during the dive.
- 5,000-lumen maximum wide-video output
- 1,500-lumen spot-light mode
- Red-light mode for night diving and sensitive subjects
- Useful for divers moving between photography and video clips
TTL, HSS and Remote Lighting for Advanced Setups
With the right camera and trigger, the HF-1 goes well beyond ordinary manual optical firing. Smart Control TTL can automate flash power on supported Sony, Olympus and OM System setups, while HSS and remote-light options open up creative workflows for macro, backlighting and off-camera lighting.
- Smart Control TTL on supported systems
- High-Speed Sync capability with compatible triggering
- Wireless off-camera control for creative remote lighting
- Large tactile controls are practical with gloves
Compare Flagship Strobes
Backscatter HF-1 vs Sea & Sea YS-D130R vs Marelux Apollo III 3.0
These are all serious underwater strobes, but they prioritize different things. Published output numbers are not directly interchangeable between guide number and watt-seconds, so the table below focuses on practical buying differences rather than pretending the measurements are identical.
| Product | Published Output | Beam | Full Recycle | Continuous Light | Best Use | System Compatibility |
|---|---|---|---|---|---|---|
| Backscatter HF-1 | ƒ40 GN | 120° / 140° / 160° | 1.6 sec | 5,000 lumens | Hybrid stills + video, wide angle, remote lighting | Fiber optic; advanced TTL/HSS varies by camera and trigger |
| Sea & Sea YS-D130R | 130 Ws | 80° × 82°; 102° × 102° with diffuser | 0.8 sec with Li-ion | Target light | Fast still shooting, cold water, traditional strobe workflows | DS-TTL II / RC / HSS options; configuration dependent |
| Marelux Apollo III 3.0 | GN44 | 120° | 0.6 sec | 3,000 lumens | Fast wildlife, burst shooting, wide-angle stills | Manual / TTL / HSS / RC / PRE-M / MTL; trigger dependent |
Buying tip: choose the HF-1 when hybrid photo/video versatility matters most; look closely at the YS-D130R or Apollo III 3.0 when maximum still-photo recycle speed is the higher priority.

Frequently Asked Questions
Backscatter HF-1 FAQ
Will the Backscatter HF-1 work with my underwater housing?
The HF-1 requires a compatible fiber-optic triggering pathway. Manual operation works with many optical systems, while TTL and HSS depend on the specific camera, housing and trigger; contact Bluewater Photo if you want us to verify your complete setup.
Does the HF-1 support TTL?
Yes. Smart Control Automatic TTL is available for supported Sony, Olympus and OM System configurations, but the correct camera and flash-trigger combination is required.
Can I use the HF-1 for underwater video?
Yes. The HF-1 includes a 5,000-lumen wide video light plus spot and red-light modes, making it much more useful for video than a conventional strobe with only a small focus light.
Are batteries included with the Backscatter HF-1?
No. Each HF-1 requires two approved high-current 21700 lithium-ion batteries, so batteries and a compatible charger should be added to your setup if you do not already own them.
Can I use any 21700 battery?
No. The HF-1 requires high-output 21700 cells that meet Backscatter's current requirements; approved examples include compatible Nitecore NL2153HP and XTAR high-output batteries.
Is the HF-1 good for macro photography?
Yes. Its adjustable manual output works for normal macro shooting, and the optional Backscatter OS-3 Optical Snoot turns the HF-1 into a much more precise creative-lighting tool.
How should I maintain the HF-1 after diving?
Rinse the exterior thoroughly in fresh water after saltwater use and keep the controls clean. Before opening the battery compartment, dry the strobe completely and inspect the dual O-rings and sand gasket for contamination or damage.
Is the HF-1 the best underwater strobe for everyone?
No single underwater strobe is best for every photographer. The HF-1 is especially strong for hybrid still/video shooters, while photographers focused purely on maximum flash recycle speed may prefer alternatives such as the Marelux Apollo III 3.0 or Sea & Sea YS-D130R.
