The Kino Flo PAR-400S-120 is a professional flicker-free fluorescent PAR-style light fixture designed for film, television, and photography applications where high-output, soft, and color-accurate illumination is required. Operating on standard 120VAC power, this fixture houses four high-CRI (Color Rendering Index) compact fluorescent lamps within a parabolic aluminized reflector (PAR) housing, producing a broad, even beam of light with minimal heat output compared to traditional tungsten PAR lights. It is engineered to deliver consistent, daylight-balanced (typically 5500K) or tungsten-balanced (3200K) light without the color shift common in other fluorescent technologies, making it a reliable tool for matching ambient light or creating a specific color temperature environment on set. The integrated electronic ballast provides full-range, flicker-free dimming from 100% down to 0.5%, allowing cinematographers and gaffers to precisely control light levels for exposure and mood without sacrificing color fidelity or creating strobing artifacts when shooting at any camera frame rate.

The fixture's design emphasizes versatility and durability in production environments. The PAR-style housing includes a glass UV filter to protect the lamps and a durable wire guard, while the integrated yoke allows for quick mounting to standard light stands, ceiling grids, or wall plates. The fixture can be used as a broad floodlight with its included diffusion lens or can be paired with optional accessory lenses (such as spot or wide-flood lenses) and barndoors to shape and control the light beam for more specific applications. Its relatively lightweight and cool operation make it ideal for use in confined spaces, on location where power may be limited, or in situations where talent comfort is a priority during long shooting sessions.

As part of Kino Flo's established lighting ecosystem, the PAR-400S-120 is valued for its plug-and-play simplicity, reliable performance, and the quality of light characteristic of the brand. It provides a powerful, energy-efficient alternative to HMI or tungsten fixtures for fill light, key light in interviews, and general set illumination. The combination of high output, excellent color rendering, smooth dimming, and low power consumption makes it a staple in rental houses and production companies, supporting a wide range of lighting scenarios from studio soundstages to documentary field work.
