Kinoflo

Kinoflo

noun | Lighting

A brand of lightweight, low-heat soft lighting fixtures for film and television, developed by Kino Flo Inc. in 1987. The fixtures use fluorescent tubes or LED emitters calibrated to film-grade color accuracy, producing soft, even light with minimal heat and low power draw. The name has become genericized on set.

Quick Reference

The Explanation: How & Why

A fluorescent tube is an extended light source, not a point source. Instead of a single filament, the entire length of the tube emits light, producing diffuse, soft-edged shadows that wrap gently around subjects. A four-tube 4Bank fixture produces an even, soft quality that a single tungsten bulb cannot match without heavy diffusion. This physical characteristic is what made Kino Flo fixtures valuable from the start: the softness is intrinsic to the source, not added through modifiers.

The second mechanism is heat. A 2000W tungsten fixture on a small interior set raises ambient temperature rapidly, making performers uncomfortable and forcing air conditioning that creates noise for sound recording. Fluorescent tubes convert electrical energy to light far more efficiently. A Kino Flo 4Bank drawing 85W produces a usable soft key that would require a 1000W tungsten fixture diffused through a large softbox. The power savings matter on location: a household circuit rated at 20 amps can run an entire Kino Flo interview setup where a tungsten equivalent would trip the breaker.

Color accuracy was the engineering problem Hochheim and Swink solved with help from a Kodak scientist. Standard commercial fluorescent tubes produce a green spike that makes skin tones look sickly on film. Kino Flo developed custom phosphor formulations that eliminated the magenta-green tints present in domestic fluorescent tubes, producing color-corrected light that matched film stock response curves without gel correction. The tubes were manufactured in both daylight (5600K) and tungsten (3200K) variants.

The LED transition brought tunable color temperature, RGBW color mixing, and wireless DMX control. The current Celeb IKON series uses a five-emitter RGB-cW-wW LED engine that drives full power to every color point, with two full-spectrum white sources for near-perfect white light across the entire CCT range. The Celeb IKON 12, launched in May 2026, delivers 1200W of output with a TLCI of 99 and TM-30 Rf of 96.3, enough to compete with direct sunlight on location.

Historical Context & Origin

Kino Flo was incorporated in 1987 by gaffer Frieder Hochheim and best boy Gary Swink. The two met on the 1985 TV film Finnegan Begin Again and first collaborated on prototype fluorescent fixtures for the 1986 film No Mercy. The breakthrough came on Barfly (1987), directed by Barbet Schroeder and shot by Dutch cinematographer Robby Muller. Muller wanted natural, real light in challenging bar locations with tight camera angles. Hochheim rigged custom fluorescent fixtures using high-frequency ballasts borrowed from an engineering group developing them for copy machines. The 28kHz ballasts eliminated the flicker that had plagued standard magnetic-ballast fluorescents on film.

Production sound mixer Peter Hliddal, impressed that the fluorescents ran silently, told Hochheim he should commercialize the design. Hochheim and Swink set up Kino Flo that same year. The company name combines German "kino" (cinema) and "flo" (fluorescent). For five years, Kino Flo operated rental-only, pouring revenue back into product development. Hochheim continued working as a gaffer and took no salary. The US patent for the portable fluorescent lighting system was granted in 1992. In 1995, Hochheim received an Academy Award for technical achievement.

How It's Used in Practice

Scenario 1 - Interview Lighting (DP): A documentary DP lights an interview in a small apartment with one 15-amp household circuit. They use two Diva Lux 4 fixtures: one as a key at 3200K slightly off-axis, one bounced off a white card for fill. The total draw is under 1000W. The same setup with tungsten would require 4000W, trip the circuit, and raise the room temperature 15 degrees within 20 minutes. The subject remains comfortable for a two-hour interview session.

Scenario 2 - Hospital Set (Gaffer): A scene set in a hospital corridor requires the look of overhead fluorescent ceiling lighting. The gaffer rigs four 4Bank fixtures above a 12x12 diffusion grid stretched across the ceiling frame. Each 4Bank draws 85W. The combined 340W load produces an even, flat top-light that reads as practical hospital fluorescent on camera, while remaining fully dimmable and color-controlled. Tungsten equivalents would generate enough heat to warp the diffusion grid.

Scenario 3 - Exterior Fill (DP): A DP shooting a night exterior on an ARRI ALEXA 35 needs soft fill for close-ups under streetlight. They use a Celeb IKON 6 at 600W, battery-powered through a 48V DC input. The IP65 rating means rain does not stop the shoot. The fixture's 2700K-9990K range lets the DP dial in 3200K to match the tungsten practicals in the scene without swapping tubes or adding gel.

Usage Examples in Sentences

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

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

"The new IKON 12 is IP65 rated. We can use it in the rain without a rain hat."

"Get me a kino for the background practical. Something soft that reads as window light."

Common Confusions & Misuse

Kinoflo (brand) vs. Fluorescent Fixture (category): "Kinoflo" is a brand name that has become genericized. Not all fluorescent or LED soft lights on set are manufactured by Kino Flo Inc. Competing products from Litepanels, ARRI, Aputure, and Quasar also serve this role. When a crew member says "get me a kino," they typically mean any soft panel of this type, not necessarily a Kino Flo branded product.

Kinoflo vs. Softbox: A softbox is a diffusion modifier placed over a hard light source (tungsten, HMI, or bare LED) to soften its output. A Kino Flo fixture produces soft light inherently from its extended source design. Both produce soft light through different physical mechanisms. A softbox adds softness to a hard source; a Kino Flo is soft by nature.

Fluorescent vs. LED Kino Flos: Older fluorescent 4Bank and Diva-Lite fixtures use replaceable tubes in fixed color temperatures. Current Celeb IKON and Diva Lux fixtures use LED emitters with tunable color temperature and RGBW mixing. The light quality is similar but the LED line offers wider CCT range, lower power draw, and no tube replacement.

Variations by Context

Key People & Films

Frieder Hochheim, a German-Canadian gaffer who studied film at Ryerson Polytechnical in Toronto, founded Kino Flo with best boy Gary Swink after developing the first fixtures on Barfly (1987). Dutch cinematographer Robby Muller took the risk of shooting an entire feature with the prototype fluorescents, giving the fixtures their first high-profile test. Muller's work on Barfly demonstrated that fluorescent light could be color-accurate and cosmetically flattering on film stock. Hochheim received the Academy Award for technical achievement in 1995. The company's fixtures have appeared on productions including Men in Black, Mission: Impossible, and thousands of television series.

The Celeb IKON 6 is the smaller variant at 600W with the same RGB-cW-wW LED engine and IP65 rating. The Diva Lux 4 is a 400W indoor softlight with TLCI 99 and TM-30 Rf of 96, designed for broadcast and film/TV. The classic 4Bank remains in production as a fluorescent fixture with replaceable tubes in daylight and tungsten color temperatures. All current LED fixtures run Kino Flo's True Match operating system for on-board and wireless control.

Standards & Specifications

Kino Flo's current LED fixtures report TLCI (Television Lighting Consistency Index) scores of 99 at both 3200K and 5600K, indicating near-perfect color rendering for broadcast and cinema cameras. The TM-30 Rf (Fidelity Index) values range from 95.7 to 96.3, and TM-30 Rg (Gamut Index) values exceed 100, indicating accurate color rendering with slight oversaturation in reds. The Celeb IKON series carries an IP65 rating under IEC standard 60529, meaning the fixtures are dust-tight and protected against water jets from any direction. Control protocols include LumenRadio CRMX wireless DMX, RDM, sACN, Art-Net, and 5-pin XLR DMX. The IKON 12 operates on 100-240VAC with an integrated power supply and PowerCON TRUE1 connector, daisy-chainable for multi-fixture runs.

Common Questions / FAQ

Q: Are Kino Flo fixtures still fluorescent?

A: The classic 4Bank and Diva-Lite fluorescent fixtures remain in production, but Kino Flo's current development focuses on LED. The Celeb IKON and Diva Lux LED lines offer tunable color temperature, RGBW mixing, and lower power draw than the fluorescent originals. Many rental houses stock both.

Q: Why do crew members call all soft lights "kinos"?

A: Kino Flo dominated the production fluorescent market for so long that the brand name became genericized, similar to "Hoover" for vacuum cleaners. When someone says "get a kino," they mean any soft panel. Aputure Nova, ARRI SkyPanel, and Quasar Rainbow fixtures all get called "kinos" on set.

Q: How much power does a Kino Flo draw compared to tungsten?

A: A 4Bank fluorescent draws approximately 85W and produces light comparable to a 1000W tungsten fixture through a softbox. A Celeb IKON 12 at 1200W produces output comparable to a 5000W tungsten softlight. The power-to-output ratio is roughly 5:1 in favor of Kino Flo.
