Long Description

Professional COB Lighting with Remote Control Flexibility

The Bigblue CB11000PB-RC 11,000-Lumen Underwater Video Light is designed for underwater photographers and videographers who need powerful continuous illumination, versatile lighting modes, and greater control over their camera lighting systems.

As part of Bigblue's CB series, the CB11000PB-RC features advanced Chip-on-Board (COB) LED technology, delivering up to 11,000 lumens through an extra-wide 120° beam. Its 5000K warm-white color temperature provides balanced illumination that helps reveal the colors and details of underwater subjects.

With dedicated red and blue LEDs and fiber-optic remote control capability, this light is particularly well suited for photographers building advanced underwater video rigs or exploring creative techniques such as fluorescence photography.

Designed for Underwater Photography and Video

Underwater lighting plays an essential role in restoring color, contrast, and subject detail.

As sunlight travels through water, colors are progressively absorbed, leaving underwater footage looking increasingly blue or green. A powerful continuous video light helps illuminate nearby subjects and reveal colors that ambient light alone may not capture.

The CB11000PB-RC supports several underwater shooting applications:

• Wide-angle underwater video: Illuminate reefs, divers, and larger marine subjects using the broad 120° beam.

• Professional video production: Build a powerful dual-light system for more balanced illumination and reduced shadows.

• Macro photography and video: Adjust brightness and positioning to illuminate smaller subjects with greater control.

• Underwater fluorescence: Use the blue LED mode with suitable yellow barrier filtration to reveal fluorescent details in certain marine organisms.

• Night diving: Switch between white and red illumination according to the subject and diving conditions.

• Marine-life documentation: Adapt lighting output and color to suit different underwater environments.

11,000 Lumens with an Extra-Wide 120° Beam

The CB11000PB-RC delivers a maximum output of 11,000 lumens, providing substantial continuous lighting power for demanding underwater video applications.

Its 120° beam angle spreads illumination across a wide area, helping minimize harsh beam edges and obvious hotspots.

This broad coverage is especially useful when filming nearby marine subjects or scenes that occupy a large portion of the frame.

For wider compositions, using two CB11000PB-RC lights mounted on separate camera arms can help reduce shadows and provide more even illumination.

Advanced COB LED Technology

The CB11000PB-RC uses Chip-on-Board LED technology, which integrates multiple LED elements into a compact lighting assembly.

This design supports high-output illumination while maintaining a relatively compact housing.

For underwater videographers, broad and consistent light distribution can make it easier to illuminate subjects without constantly adjusting the position of a narrow beam.

Combined with its powerful output and 120° coverage, the COB light source makes the CB11000PB-RC a capable option for professional-quality underwater video lighting.

Warm-White 5000K Color Temperature

The CB11000PB-RC produces white light at a color temperature of 5000K.

Compared with cooler 6500K video lights, 5000K illumination generally has a warmer appearance that can help create a natural-looking underwater video style.

This is particularly useful when filming colorful reef environments, coral formations, and marine subjects where the appearance of illuminated colors contributes to the final image.

Actual recorded color will also depend on camera white balance, water conditions, shooting distance, and ambient light.

Four Adjustable Brightness Levels

The CB11000PB-RC provides four white-light power settings, allowing photographers to adjust illumination according to subject distance, shooting conditions, and battery requirements.

Higher settings provide stronger illumination for demanding video conditions, while lower settings can help control highlights when filming close subjects and extend battery endurance.

Manufacturer-Stated Runtime

Important: The manufacturer's description states approximately 1.5 hours at maximum brightness, while the supplied technical specifications associate 1.5 hours with Level III. The exact runtime for Level IV should be confirmed before presenting a definitive maximum-output runtime claim.

Actual operating time may also vary with battery condition, water temperature, and usage.

Fiber-Optic Remote Control Ready

One of the most valuable features of the CB11000PB-RC is its compatibility with Bigblue's optional fiber-optic remote control system.

When connected to the appropriate controller and fiber-optic cable, the light can be operated from a more convenient position on the underwater camera rig.

This is especially useful when lights are mounted on extended arms, where reaching the light head can interrupt shooting.

Compatible remote-control configurations can also operate two lights using a single controller, making the CB11000PB-RC particularly appealing for dual-light underwater video systems.

Benefits of Remote Lighting Control

• Convenient adjustments: Change compatible light settings without reaching toward the light heads.

• Improved dual-light workflow: Control two compatible lights from one controller.

• Better camera handling: Keep your hands closer to the camera housing while adjusting lighting.

• Flexible video production: Adapt illumination more easily as subjects and shooting conditions change.

Important: The CB11000PB-RC is remote-control ready, but the fiber-optic cable and compatible external controller are sold separately. The included remote-control port does not provide a complete remote-control system on its own.

Dedicated 500-Lumen Red Light Mode

The CB11000PB-RC features six XPE red LEDs with a maximum stated output of 500 lumens.

Red illumination provides an alternative lighting option for night diving, low-light observation, and underwater photography.

It can be useful when preparing compositions or approaching subjects that may respond differently to red illumination than to bright white light.

However, marine animals vary in their sensitivity to red light, so it should not be assumed that this mode is invisible or non-disruptive to all species.

Built-In Blue Light for Underwater Fluorescence

The CB11000PB-RC also incorporates eight blue LEDs with a stated output of 220 lumens.

Blue excitation lighting can reveal fluorescence in certain corals and marine organisms, producing vivid colors and patterns that may not be visible under ordinary white illumination.

This makes the CB11000PB-RC an attractive option for underwater photographers interested in fluorescence photography and video.

The package includes a yellow plate, which can support fluorescence imaging configurations.

For best results, blue excitation light should be paired with a suitable yellow barrier filter on the camera lens or viewing system to reduce reflected blue light and make the fluorescent response easier to capture.

The exact filter arrangement depends on the camera and housing setup.

Rechargeable 21700×4 Battery Pack

The CB11000PB-RC uses a rechargeable lithium-ion 21700×4 battery pack designed to support its high-output lighting system.

The included charger allows the battery to be recharged between dives, making the light suitable for repeated underwater shooting sessions.

An illuminated battery level indicator helps divers monitor remaining power during operation.

Recommended Battery Charging Time

Charging time may vary depending on battery condition and charging conditions. Always use the manufacturer-approved charger and follow the supplied battery-care instructions.

Rugged Aluminum Housing for Demanding Dives

The CB11000PB-RC features an anodized aluminum alloy housing designed for regular underwater use.

Its manufacturer-tested maximum depth rating of 100 meters / approximately 328 feet provides substantial depth capability for recreational and appropriately trained technical divers.

The light measures approximately 63 mm in diameter and 140.6 mm in length.

With the battery installed, its specified weight in air is approximately 679 g.

The supplied specifications list two slightly different underwater buoyancy values, -283 g and -273 g, so the exact figure should be confirmed before publication.

Because the light is negatively buoyant, photographers building a dual-light system may benefit from adding buoyancy arms or floats to improve the overall handling of the camera rig.

Flexible Mounting Options

The CB11000PB-RC includes both a 1-inch ball mount and a Goodman glove.

The ball mount allows the light to connect to compatible underwater camera arms using an appropriate ball clamp.

This provides flexibility when positioning the light away from the camera lens, adjusting beam angles, and controlling how subjects are illuminated.

The Goodman glove provides an alternative handheld configuration for diving applications.

A protective dry bag is also included for transport and storage.

Mozaik Tip — Build a More Efficient Dual-Light System

For wide-angle underwater video, two powerful lights generally provide more balanced illumination than a single centrally mounted light.

Position one CB11000PB-RC on each side of the camera using compatible underwater arms.

Start with the lights angled slightly outward so the edges of their beams illuminate the subject.

This can help reduce harsh shadows and limit backscatter caused by illuminating suspended particles directly in front of the lens.

If you plan to use the remote-control feature, confirm compatibility between the lights, controller, and fiber-optic cables before ordering.

For underwater fluorescence photography, use the blue LED mode with appropriate yellow barrier filtration and minimize unwanted white-light contamination when capturing fluorescent subjects.
