Casselman’s paintings are made on a translucent polyester fabric, Polyscreen.  The medium he uses in all of the paintings is acrylic.  The lighting source behind all of the work is a series of red, green and blue (RGB) light emitting diodes (LED’s). 

The transformative color aspect inherent in the work is created through the mixture of RGB light.  A television or computer screen uses a similar technology to mix RGB and through impressionism creates images.  The LED’s behind the paintings are controlled in one of two ways.  The first is through the use of a device called a sequencer.  The sequencer automatically changes the level of red, green or blue and there by creates different colors of light.  The speed of the sequencer is controlled via a small knob on the side of the painting. The sequencer creates numerous colors and by adjusting the knob the color cycle can range from one to twenty minutes.  The knob also functions as the ON/ OFF switch and can also freeze any particular color.

The second method to control the LED’s is through the use of a hand held remote control.  The remote functions as the ON/ OFF, allows you to separately control the level of red, green or blue and has three “scene” or preset buttons to recall a particular color or mixture of colors.  The infrared sensor for the remote is built into the light box behind the surface of the painting.

LED’s are a revolution in the lighting industry.  Their applications are numerous and becoming common in traffic lights, rear brake lights on automobiles and will soon be a common household lighting source.  LED’s are being called “life time lights” as their longevity is rated at 50,000 hours with a less than 2% failure rate.  All of the LED’s and their necessary controlling devices (with the exception of the sequencer) are produced by Tridonic Atco in Austria (contact information below).

The light boxes are designed so that all of the components can be serviced or when necessary easily changed.  When the time does arrive that the LED’s or other devices in a painting need to be changed, you can contact Mr. Casselman or any qualified electrician in your area to do the necessary work. The paintings can function on 110 volt (USA, Canada) or 220/ 230 (Europe, Asia) volt electrical systems.
