Tegra® 455 DMX



Kino Flo's new Tegra® 455 DMX 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 455 DMX features new levels of control with DMX and onboard dimming, DMX and onboard lamp switching, remote hand-held dimming, and Universal input voltage (100VAC to 240VAC). 

The Tegra 455 DMX 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 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 3200K and 5500K True Match® lamps that display a full range of high color rendering soft light.

Tegra 455 DMX Fixture

 

   

The Tegra 455 DMX Fixture houses the lamps and includes a built-in Reflector and Harness, removable Honeycomb Louver and center mount with a baby receiver lollipop.

   
 

The built-in harness is color-coded.  The same color-code must match at each end of the lamp for proper operation.


 
   
 

Light Control

 
   

Honeycomb Louver

 

The Tegra 455 Fixture includes a 90° Honeycomb Louver (LVR-K490-P).  It is attached to the fixture with Velcro fasteners.  The Kino Flo specially designed metal foil Honeycomb Louver controls and focuses the light which narrows the light spread with minimal light loss.  A 60° Louver (LVR-K460-P) is also available as an accessory. 

   
 
   

BatWing Louver

 


BAT-W4

Another light control option is the BatWing®.  The BatWing Louver attaches directly to the lamps and gives direction to the light with minimal light loss.

 
   

Flozier

 

The Tegra 455 DMX produces a broad soft light.  The built-in barndoors can open to broaden the light.  For additional softness, a Flozier may be used.  The Flozier is cloth material that slips over the front of the fixture and provides a large area of white diffusion.  The resulting larger area of diffusion further softens the light. 

This is especially useful when dealing with reflective subject matter as a means of diffusing the reflection of the lamps in the fixture.  The harshness of lamp reflections in glasses is easily avoided.  

The Flozier is attached by stretching the two elastic cords around each end of the fixture. 

Note:  The louver should be removed before applying the Flozier.  The Flozier is available in two densities, full and half (DFS-4804, DFS-4804-H).

 

Mounting

 

The Center Mount includes a ball and socket design with a lock down handle.  It allows unrestricted fixture orientation and keeps the fixture lightweight.  The fixture can operate in either a horizontal or vertical position.  It is easily rigged on the end of a grip arm to allow positioning off camera as a key or back light for interviews. At the other end of the Center Mount is a baby receiver (16mm) that can go directly onto a light stand.

     
 

Example of the Tegra 455 rigged into a Mafer clamp with baby pin.
 

Note:  The eyelet next to the mount is used as a safety point.

 

     
 

Note: Lollipops are interchangeable.

MTP-L           Kino 41 Lollipop w/ 3/8” Pin (10mm)

MTP-LBS       Kino 41 Lollipop w/ Baby Receiver Short (16mm)
     

The Kino Offset w/ Baby Receiver, MTP-B41F (sold separately), can be used to center the weight and balance of the fixture on the stand. 

The offset receiver can also be used to under hang the fixture.

Tegra 455 DMX and Manual Control Panel

A) DMX Channels: Sets the fixture to use 1 DMX channel to dim all 4 lamps or 4 DMX channels to control lamps individually.
B) DMX OK: Lights if valid DMX signal is present.
C) DMX Address: Sets DMX address of fixture.
D) DMX-In & DMX-Out: DMX-In receives signals from Dimmer Board. DMX-Out relays DMX signals through other fixtures or instruments.
     (Note: Each Tegra 455 DMX fixture has an “AUTO TERMINATE” feature.  The last fixture that does not have an XLR cable attached
      to the DMX “Out” port will automatically terminate.)
E) Fuse: Provides circuit protection.  Note:  If fuse is “blown” or “open”, replace with same type of fuse rating as marked.

DMX Operation

The Tegra 455 features DMX control of dim levels as well as individual lamp operation.  The Tegra 455 uses 1 DMX channel to dim all
4 lamps or 4 DMX channels to control lamps individually. 

For more detailed DMX information, see the Operation Manual.

 
 
   
Manual Operation

 

F) Dimmer Knob: Manual dimming control
G) Remote Dim: Input jack for Remote Dimmer (DIM-5), sold separately.
H) Lamp Switches: Turns individual lamps on manually.

     
 

The onboard dimmer dial can manually dim lamps from 100% down to 5%.  However, it is recommended that the dimmer be used to adjust exposure levels within one f-stop.  If dimmed beyond one f-stop, the color may drift towards the magenta spectrum.

To adjust for lower light levels, the Tegra 455 DMX has four lamp switches which allow for individual lamp operation.  The combination of dimming and lamp switching gives you maximum light control without color shift.

 
   

DIM-5

 

The Remote Dimmer (DIM-5) is a useful accessory for controlling the light output when you can’t reach the onboard dimmer knob.  When the remote dimmer is plugged into the fixture, the onboard dimmer is automatically disabled.  The dimmer comes with a 15ft extension cable.

     
 
   

Cases


 

The clamshell travel case (KAS-T4-C) is recommended for travel in small vehicles and production trucks.  It has room for one fixture and a 6-Lamp carry case (KAS-C46)

The Lamps

 
  The Tegra 455 DMX operates on Kino Flo’s True Match® daylight and tungsten lamps. The 4ft T12
full spectrum tungsten and daylight balanced lamps include KF32 and KF55.  These specially formulated lamps rated at CRI 95 are unique to Kino Flo as they display a broad, even, color-correct soft light, creating a nearly shadowless display that drops off evenly. They are the only high color rendering fluorescent lamps made for the professional film and video industry. Visual effects lamps in 420nm blue for blue screen and 525nm green for green screen applications are also available.
   
 

Tegra 455 Advantages

 

Energy Efficiency

The Tegra 455 DMX 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. 

All-in-one Design

With its built-in ballast design, the Tegra 455 DMX includes DMX and manual dimming, DMX and manual lamp switching with universal input voltage from 100VAC to 240VAC.  The Tegra 455 DMX 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 removable Honeycomb Louver.  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 455 DMX 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.

Center Mount

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

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
