Lightpro StudioLine 300B - 300W Bi-Color COB Bowens Mount LED Light / App control

Lightpro StudioLine 300B Shark - Studio-Grade Power with Ballast-Free Efficiency

The Lightpro StudioLine 300B Shark is a high-powered, 315-watt bi-color COB LED fixture engineered to deliver exceptional color accuracy and consistent full-spectrum output across dedicated commercial studio, television, and cinema environments.

Built for the Demands of Modern Production

Traditional high-output lighting setups in commercial studios often compromise on cable management, floor space, and operational workflow due to heavy external ballasts and complex power blocks. This fixture completely redefines that workflow by integrating its robust power supply directly into the lamp head, utilizing a single standard IEC mains cable. This internal design streamlines rigging on overhead grid systems or compact C-stands, eliminating cable strain and clutter while ensuring stable, continuous power during demanding, multi-hour filming schedules.

A frequent limitation of bi-color fixtures is the significant drop in intensity when shifting between warm tungsten and cool daylight settings. The internal architecture of this light maintains a full 315W of pure power throughout its entire 2700K to 6500K color temperature range, producing up to 33,000 lumens at 5600K and 28,500 lumens at 3200K. Color rendition is critical for high-end commercial television campaigns (TVC) and narrative work; here, the fixture achieves a verified CRI of Ra97.2, a TLCI of Qa98.3, and a nearly perfect skin tone accuracy metric with an $R_{13}$ score of 99.2. This eliminates the flat, greyish undertones common in inferior LED chips, maintaining a neutral Duv value of +0.0013 to blend smoothly with ambient natural light or secondary studio panels.

Operating a digital cinema camera at high frame rates for slow-motion capture places massive demands on light stability. Driven by a 20kHz internal operating frequency, this unit guarantees entirely flicker-free performance across high-speed capture configurations, preventing shutter artifacts or banding. Its universal Bowens S-mount opens an extensive ecosystem of professional light-shaping tools, from deep parabolic octabanks to heavy fresnel lenses and spotlight attachments, allowing gaffers and cinematographers to sculpt, diffuse, or throw light across large green screens, talking-head interviews, or complex product setups.

Production FAQ

How does the fixture handle color temperature shifts without dropping total illumination intensity?

The Lightpro StudioLine 300B Shark utilizes a dynamic power distribution array that continuously draws a full 315W across the entire 2700K to 6500K spectrum, avoiding the output drops common in multi-diode systems.

Can this light be integrated into automated broadcast grids or centralized control desks?

The Lightpro StudioLine 300B Shark features full digital DMX control interfaces and a synchronized Leader/Follower mode, allowing seamless remote intensity and temperature mapping alongside standard lighting desk layouts.

Is the operating frequency high enough to prevent shutter artifacts during slow-motion capture?

The Lightpro StudioLine 300B Shark operates with a high-speed internal frequency of 20kHz, ensuring completely flicker-free performance and clean imagery even when shooting at extreme frame rates or narrow shutter angles.

Does this unit require heavy external ballasts or dedicated mounting headers?

The Lightpro StudioLine 300B Shark features an internal power supply completely self-contained within the compact 1.85 kg chassis, requiring only a simple, lightweight IEC cable connected directly to standard AC outlets.
