Long Description

Powerful COB Lighting for Underwater Photography and Video

The Bigblue CB7200PB 7200-Lumen Underwater Video Light combines high-output illumination, natural-looking color rendering, and versatile red and blue lighting modes in a compact underwater light.

Part of Bigblue's CB series, the CB7200PB uses advanced Chip-on-Board (COB) LED technology to deliver up to 7,200 lumens through an extra-wide 120° beam. Its 5000K warm-white color temperature and CRI 85 make it especially appealing to underwater videographers who want balanced illumination and accurate-looking subject colors.

Whether you're recording reef scenes, filming marine life, or exploring underwater fluorescence, the CB7200PB provides a flexible lighting solution for both recreational and advanced underwater imaging.

Designed for Underwater Photography and Video

As light travels through water, colors become less visible and subjects can lose contrast and detail. A dedicated underwater video light helps restore illumination to nearby subjects, making colors and textures easier to capture.

The CB7200PB supports several underwater shooting applications:

• Wide-angle underwater video: Illuminate reef scenes, divers, and marine subjects with the broad 120° beam.

• GoPro and action camera video: Add powerful continuous lighting to improve close-range underwater footage.

• Mirrorless and DSLR video: Build a compact, high-output lighting system for more advanced underwater filming.

• Macro photography and video: Adjust light output and positioning to illuminate small marine subjects.

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

• Night diving: Switch between white, red, and blue illumination according to your diving and photography needs.

7200 Lumens with a 120° Extra-Wide Beam

The CB7200PB delivers a maximum output of 7,200 lumens, providing strong continuous illumination for underwater video.

Its 120° beam angle spreads light across a wide area, helping reduce the harsh edges associated with narrow-beam dive lights.

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

For photographers seeking more balanced illumination, two CB7200PB lights mounted on separate camera arms can help reduce shadows and improve lighting coverage across wide-angle compositions.

COB LED Technology with CRI 85

One of the defining features of the CB7200PB is its Chip-on-Board (COB) LED light source.

COB technology places multiple LED elements together in a compact lighting assembly, allowing the light to produce broad, consistent illumination.

The CB7200PB also features a Color Rendering Index (CRI) of 85, helping reproduce colors more naturally compared with light sources that have lower color-rendering performance.

This is especially valuable when filming colorful reef fish, coral formations, and marine subjects where subtle differences in color contribute to the overall image.

Why Color Rendering Matters Underwater

Underwater photographers often focus on brightness, but light quality is equally important.

A high-output light with good color rendering helps reveal the natural appearance of illuminated subjects, while a broad beam provides more consistent lighting across the scene.

The CB7200PB combines 7200-lumen output, 5000K color temperature, and CRI 85 to provide a practical balance of brightness and light quality.

Warm-White 5000K Illumination

The CB7200PB produces white light at a color temperature of 5000K.

Compared with cooler 6500K underwater lights, 5000K illumination generally has a warmer appearance, which may be preferable for photographers seeking a balanced, natural-looking video style.

Actual recorded colors will also depend on camera white balance, shooting distance, water conditions, and the amount of ambient light present.

Adjustable Brightness and Extended Runtime

The CB7200PB offers multiple power settings, allowing you to adapt the light to different shooting distances and battery requirements.

The manufacturer specifies a maximum output of 7,200 lumens and the following operating times:

The supplied specifications identify 7,200, 3,600, and 1,800 lumens among the white-light output settings, but do not consistently identify the lumen output for all four runtime levels.

Higher settings provide stronger illumination, while lower settings can extend battery life and help control exposure when filming close subjects.

Actual runtime may vary depending on battery condition, temperature, and operating conditions.

Dedicated 500-Lumen Red Light Mode

The CB7200PB incorporates six XPE red LEDs, providing a dedicated red light mode with a maximum stated output of 500 lumens.

Red illumination can be useful for low-light observation, night diving, and preparing underwater photography compositions.

It offers an alternative to bright white lighting when photographers want to change how a subject is illuminated.

Marine animals respond differently to red light depending on the species, so it should not be assumed that red illumination is invisible or non-disruptive to all marine life.

Blue Light Mode for Underwater Fluorescence

The CB7200PB also features a blue light mode with a maximum stated output of 220 lumens.

Blue excitation lighting can reveal fluorescent colors and patterns in certain corals and marine organisms.

This makes the CB7200PB a versatile option for photographers interested in exploring underwater fluorescence without carrying a separate dedicated blue light.

Blue Light Output Settings

For fluorescence photography, a suitable yellow barrier filter is generally needed on the camera lens or viewing system to reduce reflected blue excitation light and make the fluorescent response more visible.

Important: A yellow fluorescence plate is mentioned in the manufacturer's product description, but it is not listed in the supplied box-contents inventory. Confirm whether it is included with the specific package before ordering.

Rechargeable Battery for Extended Diving Sessions

The CB7200PB uses a rechargeable lithium-ion 21700×4 battery pack, providing the capacity needed to support its high-output COB lighting system.

The manufacturer specifies approximately 2 hours of runtime at maximum brightness, with longer operating times available at reduced settings.

An illuminated battery level indicator helps divers monitor battery status during use.

Recommended Battery Charging Time

The rechargeable battery and charger are included with the light.

Follow the manufacturer's charging and battery-care instructions. Actual charging time may vary with battery condition and charging conditions.

Rugged Aluminum Construction for Underwater Use

The CB7200PB features an anodized aluminum alloy housing designed for demanding underwater environments.

Its compact design measures approximately 63 mm in diameter and 134.6 mm in length, making it suitable for handheld use or integration into underwater camera lighting systems.

The light has a manufacturer-tested maximum depth rating of 100 meters / approximately 328 feet.

With the battery installed, its specified underwater buoyancy is -272 g, meaning the light contributes negative buoyancy to the overall camera system.

For photographers using two lights, buoyancy arms or floats may help improve the handling and balance of the complete underwater rig.

Flexible Mounting for Camera Systems and Handheld Diving

The CB7200PB 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 clamp.

This gives photographers 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 option for diving applications.

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

Mozaik Tip — Improve Wide-Angle Video with Two Lights

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

Position one CB7200PB on each side of the camera using compatible underwater arms.

Start by angling the lights slightly outward so the edges of the beams illuminate your subject.

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

For macro video, begin with a lower brightness setting and carefully adjust the light angle to control highlights and shadows.

If you're experimenting with fluorescence, use the blue mode together with an appropriate yellow barrier filter and avoid mixing in white light when trying to capture the fluorescent response.

No-Guesswork Compatibility Guidance
