ZSYB BK-300Bi 300W Bi-Color COB LED Video Light – Bowens Mount

ZSYB BK-300Bi 300W Bi-Color COB LED Video Light

The ZSYB BK-300Bi is a professional 300W bi-color COB LED video light designed for photographers, filmmakers, production studios and content creators who require powerful continuous illumination with flexible color-temperature control.

Its adjustable 2800K–6500K output moves from warm tungsten-style light to cool daylight, while stepless 0–100% dimming provides precise control over exposure. A standard Bowens mount supports a wide selection of professional lighting modifiers, making the BK-300Bi suitable for portraits, interviews, commercial productions, product photography and filmmaking.

Powerful 300W COB LED Output

The 300W COB light source delivers concentrated continuous illumination for demanding photography and video applications. Its high output makes the fixture suitable for use as a key light, fill light or controlled background source in larger studios and professional production environments.

The supplied information does not include a lux measurement or beam angle. Actual illumination on the subject will depend on working distance, brightness, color-temperature setting and the selected light modifier.

Adjustable 2800K–6500K Bi-Color Lighting

The wide color-temperature range allows the BK-300Bi to transition between:

• Warm 2800K illumination

• Neutral white light

• Cool 6500K daylight-style output

This enables creators to coordinate the fixture with indoor practical lights, daylight and other bi-color production lights without relying on separate color-correction filters.

Smooth 0–100% Dimming

Stepless brightness adjustment from 0% to 100% allows the light level to be balanced with camera exposure, ambient illumination and other fixtures in a multi-light setup.

The smooth dimming system supports controlled adjustments without repeatedly changing the position of the light.

Professional Color Reproduction

The BK-300Bi features high CRI and TLCI performance designed to support accurate colors, realistic products and natural-looking skin tones across photography and video workflows.

Exact CRI and TLCI values have not been supplied and should be confirmed before publishing numerical color-accuracy claims.

Flicker-Free Video Lighting

Stable, flicker-free output supports professional video recording, interviews, livestreams and commercial productions. This helps maintain consistent illumination when capturing motion or working with common video frame rates.

Flicker performance may still depend on brightness level, camera frame rate, shutter speed and local power conditions.

LCD Display and Onboard Controls

The integrated LCD screen provides visible lighting information while the onboard controls allow users to adjust color temperature and brightness directly from the fixture.

No wireless, app, DMX or remote-control capability has been specified.

Low-Noise Active Cooling

An active cooling system helps manage heat and maintain stable performance during extended shoots. Its low-noise design makes the fixture more practical for video production and interview environments.

Because the light uses active cooling, microphone distance and placement should still be considered during noise-sensitive recordings.

Standard Bowens Mount

The standard Bowens mount supports a broad range of compatible light modifiers, including:

• Reflectors

• Softboxes

• Octagonal softboxes

• Lantern softboxes

• Beauty dishes

• Snoots

• Projection attachments

This compatibility allows the concentrated COB output to be softened, spread or precisely shaped for different creative setups. Modifiers are not confirmed as included.

Durable Metal Housing

The metal construction is designed for regular use in production studios and properly supported location setups. The fixture should be installed on a stable light stand rated for the combined weight of the light and selected modifier.
