Kino Flo's new Tegra® 4Bank redefines the evolution of light by combining the Academy-award winning features of the 4ft 4Bank portable system with onboard control features of the Diva-Lite 401.
The all-in-one Tegra 4Bank features new levels of control with onboard dimming, onboard lamp switching, remote hand-held dimming, and Universal input voltage (100VAC to 240VAC).
The Tegra 4Bank produces as much light as a 1000W tungsten softlight using only one third the amount of power at 2.8A (120VAC) compared to the tungsten softlight at 8.3A. Proprietary solid state electronics operate the lamps at high output, flicker-free, and dead quiet.
The built-in barndoors with newly designed hinges, honeycomb louver and center mount system make the lightweight Tegra ideal for hand-held shots, rigging in tight locations or mounting on a light stand.
The fixture takes 2900K, 3200K and 5500K True Match® lamps that display a full range of high color rendering soft light.
The Tegra 4Bank produces as much light as a 1000W tungsten softlight using only one third the amount of power at 2.8A (120VAC) compared to a tungsten softlight at 8.3A (120VAC). This is especially important when shooting on location and power availability is an issue. The low power draw is also an advantage when operating on battery inverter power sources.
With its built-in ballast design, the Tegra 4Bank includes and manual dimming, and manual lamp switching with universal input voltage from 100VAC to 240VAC. The Tegra 4Bank also comes with a 15ft extension cable with an in-line power switch. If the fixture needs to be hung out of reach, a hand-held remote control dimmer (DIM-5), sold separately, may be used. The Tegra incorporates built-in barndoors with newly designed hinges. The all-in-one, lightweight Tegra makes it ideal for fast and easy set ups.
Long Lamp Life
Lamp life of a fluorescent for the television and motion picture industry is determined more by its lumen maintenance than by its actual burn time. All fluorescent lamps display a lumen depreciation curve. This means that over time the light output gradually drops and lowers in color temperature.
True Match® Color-Correct Lamps
True Match® lamps are formulated to correspond to the spectral distribution curves of film and video cameras as well as look correct to the eye. They are designed to match the colors from quartz units or daylight sources such as HMIs. This gives the camera operator the option of mixing quartz hard light sources with fluorescent soft sources. Most lighting designers want the ability to use both qualities of light to enhance the set.
Architectural lamps are designed to optimize government-mandated standards for lumens per watt efficiencies (energy savings targets).
In order to achieve these standards, the lamps contain high levels of light in the green spectrum, which our eyes don’t perceive as inaccurate. Film and television cameras do record this added green. For example, green renders Caucasian skin tone as grayish and unattractive. The architectural lamps do not match with other studio lamps. They render colors inaccurately and make correction in post almost impossible.
In 1995 Kino Flo received a technical achievement award from the Academy of Motion Picture Arts and Sciences for the development of the first color-correct lamps for film. Kino Flo continues to be a leader in the industry introducing new developments and constantly improving the efficiencies and formulations of its lamp technology.
Heat Management Design
For Kino Flo, heat management is a critical design element of fixture design. The physical heat of the lamp or buildup of heat within the fixture will directly influence the color temperature, lumen performance and lamp life.
The Tegra 4Bank fixture design addresses these requirements:
- The reflector is vented in the back to increase airflow.
- The ends are open to minimize heat buildup.
- The lamps are properly spaced apart to maximize light output from the reflector and minimize heat buildup.
A well maintained lamp temperature extends the lumen maintenance, color temperature and life of a lamp.
The Center Mount is more flexible than a conventional yoke. A yoke limits orientation on two axes, tilt and pan. The ball center mount design enables the fixture to be oriented at any angle. An optional offset arm with baby receiver (MTP-B41F) may be used to center the weight of the fixture on a stand or can be under slung and used as an “up” light.
Cost savings attributed to fluorescents cover a broad range of concerns:
- Lower energy costs
- Less heat so lower air conditioning expenses
- No gel replacements because of low heat
- Fewer lamp replacements due to longer lamp life
- Lamp replacement labor reduced by a factor of 10
Energy Savings Calculations
With the push of reducing fossil fuel consumption, TV studios are looking at cooler, more efficient lighting systems to reduce costs and save energy. One of the most important values is Btu/kWh.
British Thermal Units per Kilowatt Hour
Any light generates a percentage of usable light and the rest in heat.
For example, a standard incandescent light bulb converts only 11 percent of its electrical input into visible light, while the rest is dissipated directly as heat. There are energy costs involved in cooling the studio environment. The measure of Btu/kWh is a means of calculating the thermal loads related to operating lighting.
Use the following information to calculate Btu/kWh:
Watts to Btu
1 kWh = 3413 Btu/hr
1 Watt = 3.413 Btu/hr
3.413 = Btu per Watt-hour
