Scores are our editorial opinion of these models, based on features, suitability and ownership trade-offs—not hands-on test results. How we chose →
We’d pick the Sea Dragon 3000F Auto.
We’d start with SeaLife Sea Dragon 3000F Auto. We would choose the 3000F Auto for photographers who want automatic brightness and flash-detection options alongside manual control. Choose Heinrichs Weikamp hw Video instead if its strengths are a better match: we like hw Video for broad scene coverage and a protected rotary control, especially when a narrow beam would frustrate the shot.
Which one suits you?
SeaLife Sea Dragon 3000F Auto

We would choose the 3000F Auto for photographers who want automatic brightness and flash-detection options alongside manual control. Use manual settings when consistent lighting between clips matters; this is the Auto model, not Color Boost.

We like hw Video for broad scene coverage and a protected rotary control, especially when a narrow beam would frustrate the shot. Its 1.1 kg weight and dedicated charging connection are real packing compromises.

What the differences mean when you buy
Continuous output and coverage
SeaLife Sea Dragon 3000F Auto
Ask the brand about this detail before ordering.
Heinrichs Weikamp hw Video
- Beam
- 170°
Start with the mode used while recording. Burst and time-limited boost values are not continuous output. Compare coverage on the same underwater or in-air basis and consider the lens you use. More total lumens do not automatically mean better subject illumination or a more even beam across a wide-angle frame.
Colour and control choices
SeaLife Sea Dragon 3000F Auto
Ask the brand about this detail before ordering.
Heinrichs Weikamp hw Video
- Colour temperature
- 4900 K
Colour temperature, colour-rendering claims and red or spot modes serve different purposes. Compare the mode you actually plan to shoot, including how it changes runtime. Where a source has conflicting CRI or output figures, resolve the discrepancy before using it to justify the purchase. Test the camera’s white-balance workflow rather than assuming one setting fixes every scene.
Battery, runtime and rig balance
SeaLife Sea Dragon 3000F Auto
Ask the brand about this detail before ordering.
Heinrichs Weikamp hw Video
- Battery
- 85 Wh Li-ion
Budget output over an actual shooting session, including repeat dives and access to charging. Compare head-only and complete kits separately, checking trays, grips, adapters and battery contents. Land weight and in-water weight answer different questions; conflicting entries should remain unresolved until the manufacturer clarifies the assembled configuration.
A closer look at both
Sea Dragon 3000F Auto
The 3000F Auto adds automatic brightness control to a broad camera light. Its sensor adjusts output between 300 and 3000 lumens, while manual operation offers full, half and quarter power. Flash detection can briefly switch the light off when an external flash fires; that function can also be disabled.
What we like
We would choose the 3000F Auto for photographers who want automatic brightness and flash-detection options alongside manual control.
What would make us think twice
Use manual settings when consistent lighting between clips matters; this is the Auto model, not Color Boost.
More about the Sea Dragon 3000F Auto →hw Video
The hw Video is a wide-angle underwater video light built around a POM and aluminium housing. Its 170° beam and protected rotary control suit broad scene illumination rather than a tight signalling spot. The manufacturer distinguishes the LED’s nominal 8500 lumens from at least 5500 lumens measured from the light in an integrating sphere.
What we like
We like hw Video for broad scene coverage and a protected rotary control, especially when a narrow beam would frustrate the shot.
What would make us think twice
Its 1.1 kg weight and dedicated charging connection are real packing compromises.
More about the hw Video →Four checks before you place an order
- Match the light’s documented continuous beam and output mode to the camera and intended shooting role.
- Confirm the runtime at that exact mode, keeping burst and reduced-power claims separate.
- Build a complete parts list for trays, arms, clamps, adapters, batteries and chargers.
- Check colour settings and controls on the actual camera rig, and resolve any source conflicts before buying.
Ask for a quote for the complete kit, including the accessories you need. That makes the price comparison much more useful.
Price, accessories and owning the equipment
A head-only price cannot be compared fairly with a kit that includes a tray, grip or mounting components. Include the cost and availability of a spare battery and compatible charger, and check the practical charging time between sessions. Existing accessories should be confirmed compatible by part number.
If upgrading, identify whether the limitation is coverage, usable continuous output, colour control or battery logistics. Buying a larger light can change handling and rig balance. Follow the manufacturer sealing, charging and battery-transport guidance; published output does not establish that a light is suitable as your primary dive-safety light.
How we scored these models & further reading
These are our subjective buying scores out of 100. We weigh the usefulness of the features, the intended diving or carrying job, and the compromises involved in owning the gear. They are not laboratory measurements, safety grades or customer averages. The verdict applies to the two named models, not everything either brand makes.
90–100: one of our first choices for the stated job. 80–89: a strong option with trade-offs. 70–79: a more specific fit. A different fit, camera, valve or dive plan can change which one you should buy.

Product details and further reading →Questions worth settling
Can I compare the number in the model name?
Only after checking what it represents. Some models use a normal continuous output while others advertise a Turbo, burst or short boost value. Compare the documented recording mode, coverage and runtime rather than assuming the name is a standard measurement.
Which is the better buy for this particular comparison?
SeaLife Sea Dragon 3000F Auto: Use manual settings when consistent lighting between clips matters; this is the Auto model, not Color Boost. Heinrichs Weikamp hw Video: Its 1.1 kg weight and dedicated charging connection are real packing compromises.
Our pick is where we would start. Choose the other model if its fit or features better match your setup—especially where a camera, valve, boot or exposure suit needs an exact match.
