Kraken Hydra 1800: Best Entry-Level Dive Light
Who It’s For
- Entry-level divers and underwater photographers
- Macro focus/side lighting specialists
- Budget-conscious shooters
- Divers wanting a reliable backup light
Key Features
- 1,800-lumen flood / 1,500-lumen spot: Dual-beam versatility
- Auto flash-off feature: Prevents overexposure when strobe fires (can be toggled)
- Ultra-compact: Only 205g on land, 105g underwater
- 80-minute burn time: Longest runtime in the Hydra lineup
- USB-C charging: No cradle needed, direct charging
- 21700 battery: Modern, high-capacity cell
What We Like
The Hydra 1800 is the baby of the family and an excellent entry point into the Hydra series. At just 205g, it’s incredibly portable and perfect for macro shooters who need focus/side lighting without the bulk.
The auto flash-off feature is unique—when your strobe fires, the light automatically turns off to prevent overexposure. Great for macro photographers who want to use continuous light for focusing but strobe light for the actual shot.
The dual flood/spot design gives you versatility: wide flood for general illumination or tight spot for signaling and focusing.
Limitations
Lower output than other Hydra models. No WRGBU color modes (just wide, red, spot, burst). Not snoot-compatible. Best suited for macro and close-range work rather than wide-angle video.
Bottom Line
Best entry-level dive light and macro focus tool. Affordable, lightweight, and practical.

Kraken Hydra 3000 V2: Best Compact Video Light for Travel & Macro
Who It’s For
- Macro photographers and videographers
- Travel divers who prioritize light weight
- Beginners stepping up from dive lights
- Budget-conscious video shooters
Key Features
- 3,000-lumen output: Bright flood beam for macro and close-up work
- WRGBU color modes: White, red, green, blue, UV for creative lighting
- Ultra-compact: Only 350g on land, 140g underwater—fits easily in carry-on
- Upgraded V2 controls: Power dial + button for precise adjustment
- 50-minute burn time: Enough for most recreational dives at full power
- Snoot compatible: Add a snoot for focused macro lighting effects
What We Like
The Hydra 3000 V2 is the most travel-friendly video light in the lineup. At just 350g, it won’t eat into your baggage allowance. The upgraded V2 adds a power dial for fine-tuning output underwater—a major improvement over the original single-button design.
For macro work, 3,000 lumens is plenty. The WRGBU modes are surprisingly useful: red light doesn’t spook shy critters, blue creates moody effects, and UV reveals fluorescent marine life.
Snoot compatibility makes this ideal for creative macro lighting—use a snoot to create dramatic spotlighting effects on small subjects.
Limitations
No remote control compatibility. No float option. If you’re shooting wide-angle, you’ll want more power.
Bottom Line
Best value for macro and travel video. Compact, affordable, and capable.

Kraken Hydra 5000: Best Compact Light with Pro Features
Who It’s For
- Divers who want serious power in a compact package
- Compact camera rig users
- Shooters who value ergonomics and travel-friendliness
- Divers who want remote control in a smaller light
Key Features
- 5,000 lumens constant / 6,000 burst: Serious output for the size
- 90 CRI: Professional-grade color accuracy
- Redesigned compact body: Smaller and lighter than previous Hydra 5000S+
- WRGBU + UV modes: Full creative control
- RC V2 remote compatible: Control with the RC02 remote (unique for this size)
- USB-C fast charging: Modern, convenient
- 11 power levels: Precise dial control
- Snoot compatible: Add a snoot for creative lighting
What We Like
The Hydra 5000 is Kraken’s answer to divers who want pro-level performance without the bulk. At 520g on land, it’s significantly lighter than the 10K or 12K, but still delivers 5,000 lumens of CRI 90 light.
The big news: the 5000 is remote compatible—unique for a light this compact. Most compact lights skip remote control to save size, but Kraken includes it here. Perfect for dual-light compact rigs.
The redesigned compact form makes it perfect for travel and smaller camera rigs. The 120° beam angle provides wide, even coverage—great for both macro and wide-angle work.
Limitations
Burn time is shorter than larger models (~35 minutes at 100%). No float option.
Bottom Line
Best compact light with pro features including remote control. Perfect balance of size and performance.

Kraken Hydra 10K: Best All-Around Underwater Video Light
Who It’s For
- Recreational to advanced underwater videographers
- Shooters who want flexibility for macro AND wide-angle
- Anyone looking for the “Goldilocks” light—not too big, not too small
Key Features
- 10,000 lumens constant / 12,000 burst: Serious power in a mid-sized package
- 90 CRI + 5600K: Exceptional color accuracy
- 120° beam angle: Wide, even coverage
- RC V2 remote compatible: Control two lights via the RC02 remote
- Push-button + dial control: Fast, intuitive adjustments
- USB-C fast charging: ~3 hours to full
- ~60 min runtime @ 8K / ~35 min @ 10K: Solid battery life
- Float available: Optional float block for neutral buoyancy
- Snoot compatible: Add a snoot for creative lighting
What We Like
This is the light we recommend most often. The Hydra 10K strikes the perfect balance between power, size, and features. At 740g on land (350g underwater), it’s portable enough for travel but powerful enough for wide-angle work.
The 90 CRI is a noticeable upgrade—colors look richer and more accurate, especially reds and oranges that get lost at depth. The dial control gives you precise output adjustment, so you can match ambient light perfectly.
Remote compatibility is a game-changer for dual-light setups. Optional float blocks are available for neutral buoyancy underwater—makes handling easier and prevents drops.
Limitations
Heavier than the 3000 V2 or 5000, so weight-conscious travelers may prefer those. At full 10K output, battery drains in ~35 minutes (though most shooters run at 60-80% to extend runtime).
Bottom Line
Best all-around choice for most divers. Power, features, and portability in one package.

Kraken Hydra 12000: Best for Advanced & Professional Shooters
Who It’s For
- Advanced underwater videographers shooting DSLR/mirrorless
- Pros who need maximum creative control
- Wide-angle shooters in challenging conditions
- Dual-light users
Key Features
- 10,000 lumens constant / 12,000 turbo: Massive output
- 120° beam angle: Ultra-wide coverage

- Float available: Optional float block for neutral buoyancy
- Snoot compatible: Add a snoot for creative lighting
What We Like
The Hydra 12000 is where the series gets serious. 10,000 lumens in constant mode lights up massive subjects—manta rays, whale sharks, entire wreck sections. The 120° beam provides edge-to-edge coverage with no hotspots.
The OLED display is sharper than standard LCDs and easier to read at a glance. Turbo mode (12,000 lumens) is useful for short bursts when you need maximum light.
Limitations
At 1,035g on land (450g underwater), this is a substantial light. Not ideal for long hikes to dive sites. Price jumps significantly from the 10K.
Bottom Line
Best for advanced shooters who need maximum power and control.

Kraken Hydra 18000: Best for Professional Wide-Angle & Broadcast
Who It’s For
- Professional underwater videographers and cinematographers
- Broadcast and documentary shooters
- Wide-angle specialists working in 4K, 6K, 8K
Key Features
- 18,000 lumens: Most powerful light in the lineup
- 120° beam angle: Ultra-wide, even coverage
- 90 CRI + 5600K: Broadcast-grade color accuracy
- WRGBU modes: Full creative control
- RC V2 remote compatible: Dual-light control
- OLED display: Pro-level interface
- 60 min @ 100%: Remarkable runtime for the output
- Float available: Optional float block for neutral buoyancy
- Snoot compatible: Add a snoot for creative lighting
What We Like
The Hydra 18000 is a beast. 18,000 lumens lights up entire reef walls, large pelagics, or deep wreck interiors. At this output level, you can shoot wide-angle in conditions that would leave other lights struggling—murky water, deep dives past 30m, caves and caverns.
Build quality is exceptional. Everything feels overbuilt and designed for hard professional use. The WRGBU modes with independent power control let you dial in exactly the color and intensity you want.
Limitations
Big and heavy: 1,400g on land, 600g underwater. You’ll want a dedicated case and solid ball arm mounts. The price reflects professional specs—if you’re not shooting for clients, the 12K or 10K will serve you well at lower cost.
Bottom Line
Best for pros who need maximum power and broadcast quality.

Accessories: Snoots & Floats
Snoot (Available: Hydra 3000 V2 and up)
A snoot creates focused spotlighting effects for creative macro work. Attach a snoot to your Hydra light (3000 V2, 5000, 10K, 12000, 18000) to control light spill and create dramatic, directional lighting on small subjects.
Use cases: Highlighting specific coral polyps, isolating nudibranchs, creating dark backgrounds in macro shots.
Floats (Available: Hydra 10K, 12000, 18000)
Optional float blocks make your light neutrally buoyant underwater, eliminating arm fatigue on long dives and preventing accidental drops.
- KR-FB04 Float for Hydra 10K – 370g float block ($34.99 USD)
- KR-FB03 Float for Hydra 12K – 450g float block ($34.99 USD)
- KR-FB02 Float for Hydra 18K – 640g float block ($39.99 USD)
Understanding WRGBU Color Modes
Hydra lights (3000 V2 and up) include WRGBU modes: White, Red, Green, Blue, UV. Here’s when to use them:
White (Standard Mode)
- Use for: 99% of underwater video
- Why: Restores natural colors lost at depth
Red
- Use for: Focusing without disturbing wildlife, night dives
- Why: Many marine animals can’t see red light
Green
- Use for: Creative lighting, backlit scenes
- Why: Green penetrates water well and creates dramatic effects
Blue
- Use for: Night dives, moody effects
- Why: Enhances the “blue” underwater feel
UV (Ultraviolet)
- Use for: Fluorescent diving, revealing hidden patterns
- Why: Makes fluorescent corals glow
- Note: Requires yellow filter on camera lens
What Is CRI and Why Does It Matter?
CRI (Color Rendering Index) measures how accurately a light reproduces colors vs natural sunlight. Scale: 0-100.
- CRI 90 (Hydra 5000, 10K, 12000, 18000): Excellent color accuracy—reds, oranges, purples look vibrant and true
Why it matters: At depth, water absorbs red/orange/yellow wavelengths first. High-CRI lights restore these colors more accurately.
When it’s critical: Shooting colorful marine life—coral reefs, tropical fish, nudibranchs.
