Kinoflo

Kinoflo

noun | Lighting

A brand of lightweight, low-heat fluorescent lighting fixture developed specifically for film and television production by Kino Flo Inc. in the late 1980s. Kinoflo fixtures use fluorescent tubes with high colour rendering index (CRI) ratings calibrated to either daylight (5500K) or tungsten (3200K) colour temperatures, producing a soft, even, flattering light with minimal heat output and very low power consumption compared to traditional tungsten or HMI fixtures. The brand name has become genericised in professional usage — crew members frequently refer to any fluorescent lighting fixture used on set as a "kino" or "kinoflo" regardless of manufacturer.

Quick Reference

The Explanation: How & Why

Kinoflo fixtures were invented to solve specific practical problems in film and television lighting that existing tungsten and HMI fixtures could not address effectively.

The problems Kinoflo solved:

Heat: Tungsten fixtures produce enormous quantities of heat. A 2000W tungsten light on a small interior set raises the ambient temperature rapidly, making conditions uncomfortable for performers and crew and requiring air conditioning that creates noise problems for sound recording. Kinoflo tubes are fluorescent — they convert electrical energy into light much more efficiently, producing a fraction of the heat of an equivalent tungsten fixture.

Weight and rigging: Tungsten fixtures are heavy and require robust mounting hardware. Kinoflo fixtures are lightweight and can be rigged in spaces that cannot support heavy equipment — mounted directly to ceilings with minimal hardware, taped to walls, or held by a single crew member.

Power consumption: Fluorescent tubes use a fraction of the power of equivalent tungsten lights. On location, where available power is limited, Kinoflos allow cinematographers to achieve adequate light levels without overloading circuits or requiring generator support that tungsten setups would demand.

Colour accuracy: Early fluorescent lights had poor colour rendering — they produced a greenish cast that required correction and made skin tones look unpleasant. Kino Flo developed tubes specifically calibrated for film and television production, with high CRI ratings that produce accurate colour rendition without the green spike of commercial fluorescent lighting.

The quality of Kinoflo light:

Kinoflo light is intrinsically soft. A fluorescent tube is an extended light source — rather than a point source like a tungsten bulb, it is a long, luminous element that produces diffuse, soft-edged shadows. A four-tube 4Bank fixture (the most commonly used Kinoflo format) produces a soft, even light that wraps gently around subjects and produces very soft shadow transitions. This quality makes Kinoflos particularly valuable for:

• Close-up lighting where hard shadows would be unflattering
• Interview lighting where a naturalistic, soft look is required
• Practical lamp effects in interior scenes
• Filling shadow areas without introducing harsh secondary shadows

LED transition:

Kino Flo has progressively transitioned from fluorescent tube technology to LED, producing their FreeStyle and Celeb LED series fixtures. LED Kinoflos offer the same soft, low-heat characteristics with even lower power consumption, a wider colour temperature range (tunable from tungsten through daylight in a single fixture), and RGBW colour mixing capability that allows creative colour effects beyond the two fixed colour temperatures of fluorescent tubes.

Historical Context & Origin

Kino Flo was founded in 1987 by gaffer Frieder Hochheim and production designer Dana Rösler after they encountered the practical limitations of available lighting for the production of the television series Murphy Brown. They needed a soft, low-heat light source that could work in practical interior locations without overwhelming the space with heat and power demands. The first Kinoflo fixtures were hand-built and used on that production; their success led to commercial manufacture. The product rapidly became standard equipment across film and television production. The Kinoflo name became so associated with the category of production fluorescent lighting that it entered general use as a common noun — a significant commercial achievement that also reflects the product's genuine dominance of its market.

How It's Used in Practice

Scenario 1 -- Interview Lighting (DP): A documentary DP is lighting an interview in a practical domestic interior. Available power is limited to standard household circuits. The DP uses two Kinoflo Diva-Lites — one as a key light slightly off-axis, one bounced off a white card for fill — alongside a small LED backlight. The entire setup draws less than 500W, produces a flattering soft light on the subject, and generates no heat that would make the interview subject uncomfortable. The same setup with tungsten lights would require 4000W and make the room uncomfortably hot within minutes.

Scenario 2 -- Hospital Set (Gaffer / DP): A scene set in a hospital corridor requires the feeling of fluorescent ceiling lighting. The gaffer rigs multiple 4Bank Kinoflos above a diffusion grid stretched across the ceiling, creating the effect of practical fluorescent ceiling fixtures while maintaining controlled, colour-accurate light at a manageable power level. The result reads as practical overhead fluorescent lighting while actually being fully controlled studio light.

Scenario 3 -- Small Set With Actors (DP): A long dialogue scene in a practical apartment requires several hours of shooting with two actors in close proximity to the lights. The DP uses Kinoflo fixtures as the primary sources because their minimal heat output means the actors remain comfortable throughout the day without the temperature rises that tungsten-heavy setups would produce. The sound recordist is also able to work without competing with air conditioning noise.

Usage Examples in Sentences

"Put a 4Bank on a low stand camera left. I want soft fill across the whole face."

"The Kinoflo is the documentary DP's best friend. It runs on almost nothing, produces no heat, and makes skin look good."

"We only have one 20-amp circuit in this location. Kinoflos can run the whole setup on that."

"The new FreeStyle LEDs are tuneable — you can dial in any colour temperature from 2700K to 6500K in the same fixture."

Common Confusions & Misuse

Kinoflo (brand) vs. Fluorescent Fixture (category): "Kinoflo" is a brand name that has become genericised in professional use. Not all fluorescent or LED soft lights used on set are manufactured by Kino Flo Inc. — competing products from Litepanels, ARRI, Aputure, and others are also used. When a crew member says "get me a kino," they typically mean any fluorescent or LED soft fixture of this type, not necessarily a Kino Flo branded product.

Kinoflo vs. Softbox: A softbox is a rigid or collapsible box with a diffusion front panel placed over a hard light source — typically a tungsten or LED point source — to soften and diffuse its output. A Kinoflo is a self-contained fluorescent or LED fixture that produces soft light inherently from its extended light source design. Both produce soft light; they achieve it through different physical mechanisms.

Related Terms

• Key Light -- Kinoflos are frequently used as key lights in interview, documentary, and naturalistic narrative setups
• Soft Focus -- The quality of soft light that Kinoflos produce is related to the soft focus aesthetic in close-up photography
• Diffusion -- Kinoflo fixtures can be further softened with diffusion materials; their inherent softness makes them useful in combination with diffusion frameworks
• Three-Point Lighting -- Kinoflos are commonly used within three-point lighting setups, particularly for key and fill in television and documentary contexts
• CTB/CTO/CTS -- Gels applied to fluorescent tubes or fixtures to adjust colour temperature where the available tube colour does not match the production's target balance
