Ratpac Dimmers and the At Large Musical Festival/EXPO

Ratpac Dimmers – Back in the 50s and 60s, the lighting at music festivals and concerts served only to illustrate the performers and nothing more. No one had quite yet thought about marrying light with sound in order to enhance the experience for concert goers and performers alike. The 70s and beyond introduced a whole host of flamboyant performers and bands who used music to augment their unique styles and accent their distinctive compositions. Today, spectacular lighting is one of the primary considerations stage managers use in order to put together a show. That is why Ratpac Dimmers is so excited to be a part of the upcoming 1st annual At Large Musical Festival/EXPO which runs Oct. 27 through 29 at Georgia State University in downtown Atlanta

What is the At Large Musical Festival/EXPO?

The festival is a collection of passionate artists, educators, business professionals, and volunteers who are gathering with the goal of creating a go to place for projects such as documentaries, features, music videos, V.R., etc. The festival’s creators believe that music and film are two perfectly paired media that up and coming artists must take every opportunity to use in their favor. Atlanta, as it so happens, has a long, rich tradition of being the launching point to many artists, educators and business professionals.IMG_0999


As we have said, Ratpac Dimmers would not miss the opportunity to attend such an important event and to showcase our wireless DMX. It will give artists and merchants a chance to interact and to ultimately move the industry forward with all the latest and greatest in wireless dimmer packs. Other attendees will include: Paul Miller (DJ Spooky) composer, multimedia artist, editor and author, DeVaughn Hughson, filmmaker, photographer, documentarian, Kathy Gray, Director of Operations & Creative Services, Crawford Media, Jeff Brugger, Creative Services Director of Sound Design at Turner Studios and many others.

Workshops and Discussions

The exchange of information is the primary function of the Festival. Aiding this goal will be workshops and discussions on the following topics and many others: Immersive Music in VR hosted by composer and technologist with Tunewelders, The Art of Scoring Silent Film by DJ Spooky and Bret Wood, The Role of Music in her Creative Process by Barbara McCullough and many more. (For a detailed list of the workshops and discussions that will be held at the festive go here.

In conclusion, our products such as our Ratpac wireless dimmers and our Ratpac Cintenna kits are a perfect match for the attendees of this first time event. We hope that our association with the event will be a long and fruitful one and that it will advance the lighting industry and further strengthen the bound that exists between music and light.

The Top 5 Greatest Cinematographers of all Time

As the entertainment industry becomes more and more invested in completely immersive technologies, it should always be remembered that motion pictures are still primarily a visual medium. It is through the use of light and shadow, brightness and contrast, color and saturation that directors seek to carry us along with them as they convey stories that will make a lasting impression on us. Aiding them in this task are cinematographers. They must take all of the aforementioned tools and sculpt them into an experience that all involved in the project can be proud of and that the public will enjoy. We honor five of the cinematographers who stand out from their peers in this difficult task by including them in this list.

  • Roger Deakins: British born Roger Deakins is best known for his work on the films of the Coen brothers and Sam Mendes. He has received accolades from the British Society of Cinematographers as well as multiple Academy Award nominations. His movies include: The Shawshank Redemption, Dead Man Walking, O Brother, Where Art Thou? A Beautiful Mind, True Grit and many others.
  • Robert Burks: Best known for his collaborative work with Alfred Hitchcock, Burks is often referred to as a chameleon for his ability to adapt to any director with which he worked. Some of Cinematographers_The_Birds_original_posterhis works include Strangers on a Train (1951), The Spirit of St. Louis (1957), The Music Man (1962), Vertigo (1958), the Birds (1963) and Marnie (1964).
  • Jack Cardiff: Director Michael Powell once described British born Cardiff as “the best colour cameraman in the world” (Cardiff’s illustrious career began in the silent era.) His resume includes the movies Black Narcissus (1947), War and Peace (1956), Fanny (1961), The Red Shoes (1948), Ghost Story (1981) and many others.
  • Janusz Kaminski: Kaminski is best known for his partnership with Steven Spielberg and has been a cinematographer since 1993. He has won the Academy Award for his work on Spielberg’s Schindler’s List (1993) and for Saving Private Ryan (1998). His other works include Amistad (1997), I. Artificial Intelligence and many others.
  • Vilmos Zsigmond: Zsigmond fled Hungary in 1956 and began his career in the 1970s. He is known for his use of natural light and vivid color. His works include The Long Goodbye (1973 ), Close Encounters of the Third Kind (1977 ), The Deer Hunter (1978), The Witches of Eastwick (1987), The Ghost and the Darkness (1996) and many others.

We know that this list is debatable and many greats are not included here but these are cinematographers who we feel deserve a special mention for elevating the art of movie making. Their works are a part of posterity. They are noted for combining the latest technologies of the time with their own natural knowledge of the medium.

Wireless DMX, Skylink and SkyPanel: The Next Logical Step

The most exciting thing about being a part of the lighting industry is witnessing how one technology is often combined with another to enhance the quality and functionality of both innovations. This is the case with ARRI and Innovative Dimmers who have teamed up to create Skylink a two-part system that allows for wireless DMX and RDM communication to SkyPanels. What are SkyPanels? SkyPanels are a compact, ultra-bright and high-quality LED soft light. They incorporate the features of ARRI’s L-Series LED Fresnels. In short, SkyPanels are one of the most versatile soft lights on the market, as well as one of the brightest. They come in a variety of shapes and sizes and thus can be used as a soft light or a space light. Innovative Dimmers and Ratpac Dimmers use the same kind of wireless dimmer technology and have eliminated the need for DMX cables.


This new creation, Skylink, increases the innovative features of SkyPanels which among other things are cable of


  • Being matched with existing light sources
  • Fitting into tight locations
  • Adjusting from 2.8k to 10kskylink_prod
  • Having hue and saturation control
  • Being able to be used in multiple configurations
  • An easily shaped beam
  • Move around from one location to another easily

One can easily see the many applications for which SkyPanels can be used. It is also not too difficult to see how this added convenience is made possible due to wireless DMX technology. SkyPanels can be used outdoors or inside, in theatre productions as well as concerts and in Television products and by the movie industry. These technologies merging in the way they have, demonstrates the innovation that our industry is constantly achieving. Ratpac Dimmers is a part of that innovation and is proud when a technology that we commonly use can be made to enhance another exciting device. Our wireless DMX technology is state of the art. We are very much excited to see how this creation – Skylink – evolves even further.


Ratpac Dimmers: Illuminating the Future of Entertainment Lighting

There is a reason why the effects that the movie going public knows are referred to as “the magic of Hollywood.” Entertainment lighting experts constantly face the challenge of creating spectacular on- screen effects that are eye-popping and that propel the story they are trying to convey while at the same time concealing the means by which they perform this “magic” from the public. This is why they rely, more and more on our technologies that are unobtrusive and that not only help to create spectacular displays, but are more or less hidden from public view. A small list of productions that have or who are currently using our wireless dimmers and LumenRadio’s industry leading CRMX technology are:

● Gone Girl
● Fantastic Four
● Pitch Perfect
● Trumbo
● Free state of Jones
● Roots
● Avengers: Civil War II
● Jurassic World
● Passengers
● Bad Moms

Sci-fi films such as the Fantastic Four, Jurassic World and Avengers: Civil War II in particular create challenges for gaffers and lighting artists as audiences have become more demanding with each movie that comes out of Hollywood. They expect to be wowed and to let down viewers can be a death sentence for these kinds of movies that cost millions of dollars. Similarly, letting down our customers by not providing them with the latest lighting technology is not an option for us. Cintenna receivers – which plug directly into a lighting fixture without extra hardware, zip ties or cable – are especially helpful for lighting professionals who are looking for the most efficient and quickest way to communicate with an array of other equipment. We sell to bigger companies like the major studios and rent to smaller ones, equipment that can make all the difference in a production. And as anyone who works in the field of movie or TV production knows, further complications in producing features are not needed. There are a lot of moving parts that must be managed in producing a 90-minute or even a 30-minute production.

In other words, the strength of our products as everyone from lighting technicians to gaffers to other artists can attest to is that they are easy to use, reliable and functional. The productions listed here encompass several different genres which call for different and very specific lighting demands. This is why our product is used by these professionals or as Erik Messerschmitt – Chief Lighting Technician on The Fantastic Four and Gone Girl says, “They have changed the way we work for the better. Such a great product.”

A Brief History of Wireless Communications

While not quite the dinosaur that telephone booths are, wired communications is rapidly disappearing from our modern day society. Wireless is more convenient, faster and simpler to use and despite what some people believe, it can be secure. But this boon in wireless technology did not just spring up overnight. A lot of people laid the groundwork for the wireless keyboards, headphones, speakers, dimmers, etc. Here are just a few milestones on the path of our decreasing dependence on wired communications.

  • Early 1820s: Electromagnetism is discovered by Hans Christian Ørsted and Andre-Marie Ampere.
  • 1896: Guglielmo Marconi and W.H. Preece send wireless signals over a distance of one-and-three fourths miles on Salisbury Plain. (Early that year Marconi patented an operational wireless telegraph apparatus.)
  • 1906: Lee DeForest patented the first triode amplifier. The first speech wireless transmission was broadcast by Reginald Fessenden.
  • World War II (1941-1945): The war years see the rapid advancement of radio technology. Shortly after the war two papers are published on Information theory. These papers contain the basis of data compression (source encoding) and error detection and correction (channel encoding).
  • 1954: Many Americans get their first glance of a wireless mobile car phone in the movie Sabrina starring Humphrey Bogart, William Holden and Audrey Hepburn. (The first car-based mobile telephone was set up in St. Louis, using ‘push-to-talk’ technology.)
  • 1962: The first communications satellite, Telstar, is launched into orbit. Telstar was a U.S., French, and British collaboration that was the world’s first active communication satellite.
  • 1974: The Federal Communications Commission (FCC) allocates 40 MHz for cellular telephony.
  • 1982: European GSM and Inmarsat established.
  • 1990: Motorola files and is given permission by the FCC to launch 77 low orbit satellites into orbit.
  • 1994: The FCC licenses the Personal Communications Services spectrum (1.7 to 2.3 GHz) for $7.7 billion.
  • 1998: IBM, Intel, Nokia and Toshiba join forces to develop Bluetooth for the wireless exchange of data between handheld computers or cell phones and stationary computers.

Today as the public has gotten used to the convenience of wireless communications, companies like ours have – out of necessity – had to accommodate this need. Wired technologies, though they will probably never be completely replaced, are simply not practical in a number of situations. Ratpac Dimmers stands on the shoulders of giants and continues to innovate in ways that the early pioneers of wireless communications could not have possibly imagined.

The Harry Potter Light Show 2017

First J.K. Rowling’s Harry Potter books captured the imagination of children all over the world. After that the books were transformed into blockbuster movies that adults and children from all over the world have enjoyed for years. Now, the story of a student/magician is being translated into a Universal Studios light show that some people say will be a “bone-chilling adventure.” The show, which will launch on June 23, will be the culmination of years of planning by expert light technicians. Universal Studios is counting on this display to be the perfect blending of light, color and music. The music will be scored by Academy Award-winning composer John Williams — who composed the music for the first three Potter films.

The display will be a five-minute show, called “The Nighttime Lights at Hogwarts Castle.” This display was inspired by the Wizardry World of Harry Potter ceremonies last year. “We really wanted the guests to have that bone-chilling moment and go, ‘Wow, this is something I’ve never experienced before,’” says Stacey Quinealty, the park’s senior manager of audio and visual production. Universal Studios is no stranger to displays of pop culture references. In the past it has had to coordinate and plan displays such as The Flintstones, The Star Trek Adventure, E.T. Adventure, Back to the Future, etc. However, as technologies develop and change, expectations grow as well.

The light show – which will have audio piped in through a 27.5 surround-sound system – is an example of how light technologies have to be adaptive in the 21st century. Audiences who have come to know and love the Potter books and movies will be expecting visuals that are truly immersive. Ratpac Dimmers provides technologies that are utilized by the makers of such events every day. We understand that the logistics of a venue like Universal Studios are too complicated to accommodate wired lighting fixtures. It is not practical for people who work with enormous displays that must be synchronized in this way to be tethered to old, wired technologies. Quite a bit of state-of-the-art technology is needed to make such experiential events. That is why we take pride in our wireless dimmers, our portable DMX wireless receivers, etc. They make events such as the one that will be held in Universal Studios during the summer of 2017 possible.

So, whether you are a Potter Fan or not, we invite you to look over some of our state-of-the-art technology that experts in the field of lighting use every day due to its simplicity of operation and reliability. Have a fun summer.

Terms that Every Stage Lighting Student Should Know

Every profession has its own personalized jargon. These highly specialized terms may seem baffling to people who are outside of that profession, but to experts within those given fields they are an important tool for communicating effectively with others in that area of expertise. In the field of stage lighting, it is no different. It is incumbent upon lighting students to begin to master the specialized words and terms that are so essential to the craft. Here are some basic lighting terms that students and event lighting people should know.


    • ACN: Advanced Control Network. This is an Ethernet-based control protocol between control desk, dimmers & moving lights. It was developed by Strand Lighting, et al in 2003.
    • Backlight: This is a light that comes from upstage, behind scenery or actors. It helps to separate them from the background. Tip: Smoke, steam, and other Translucent work very well with backlighting.


  • Intelligent lights: These lights that can be controlled and programmed by sophisticated lighting software and hardware systems.
  • Non-Intelligent lights: These are basic, static light fixtures that move to music (as in rock concerts, etc.)
  • Vertical and Horizontal Truss: Vertical truss systems are hollow, steel columns that stand on either side of a stage’s floor and support lights. Horizontal truss columns usually rest above or below a stage allowing them to lay over or below it.
  • Digital dimmer: A digital dimmer responds directly to the multiplexed output of the lighting desk. This technology permits the dimmer to report faults and other data back to the control board.
  • Dimmer: This is an electronic or electric device that reduces a fixture’s brightness sometimes with a corresponding loss of color temperature. Optical dimmers maintain color temperature.
  • Dimmer Hookup: This is a spreadsheet that lists each fixture in a show with all its relevant information, including, color, template, accessories, dimmer, circuit, channel, wattage, and purpose.
  • DMX Terminator: This device regulates DMX fixtures when many fixtures are used on a single DMX line (Universe). Its function is to remove excess noise and flickering on the DMX Tx line.
  • GOBO (short for Graphical optical blackout): This is a physical stencil or template that is placed inside or in front of a light source, to control the shape of the emitted light.


Finally, knowledge of these specialized terms – and many others – will help you communicate better with lighting experts if you are outside of the field and help you communicate with peers if you are a lighting specialist.
