The Kino Flo BAL-210-S120 Ve is a sophisticated, flicker-free electronic ballast designed to operate Kino Flo's renowned Diva-Lite and other compatible 120-volt fluorescent lighting fixtures. This "Double Select" ballast is a cornerstone of Kino Flo's technology, enabling the precise dimming and control that has made their fixtures a staple in film, television, and photography for creating soft, natural-looking illumination. The ballast provides power and control for two independent fluorescent lamp channels, allowing a single fixture like the Diva-Lite 400 to operate as either a powerful, full-output source or a softly dimmed light with stable color temperature. Its advanced high-frequency electronics completely eliminate the perceptible flicker that plagues standard magnetic ballasts, ensuring clean, consistent light output that is safe for high-speed camera shooting under any frame rate.

A defining feature of this ballast is its dual-channel "Double Select" functionality, which offers independent control over two sets of lamps within a fixture. This allows cinematographers and gaffers to achieve a wide range of output levels and subtle lighting effects by switching between two-lamp, four-lamp, or selectively dimmed configurations via the ballast's rear panel switches. The ballast also provides full-range, flicker-free dimming from 100% down to 0.5% without shifting the lamp's calibrated color temperature—a critical requirement for maintaining consistent skin tones and scene continuity. The "Ve" designation indicates a quiet, fan-cooled design suitable for environments where microphone placement is critical, as the ballast generates minimal operational noise that could interfere with audio recording.

Housed in a durable, compact metal casing, the BAL-210-S120 Ve is built for the rigors of location and studio use. It features standard industry connectors for secure cabling to the fixture head and integrates seamlessly into Kino Flo's ecosystem of accessories and controls. The ballast can be operated manually via its onboard controls or interfaced with external DMX512 controllers for integration into larger, digitally managed lighting setups. By delivering exceptional dimming performance, flicker-free operation, and versatile control in a reliable package, this ballast is an essential component that unlocks the full creative potential of Kino Flo's fluorescent lighting systems, providing lighting professionals with a trusted tool for crafting precise and beautiful illumination.
