The old PAR-64 type stage lights with mylar color filters are quickly becoming a thing of the past, replaced with very powerful and bright LED array lights that can be programmed to generate any color imaginable by controlling and mixing the LED output colors. These are very high powered LEDs, arranged in a pod and are every bit as bright as the 300 or 500 watt single incandescent bulbs they are replacing. They also draw a tiny fraction of the power and generate very little heat compared to the bulbs they are replacing. Residential, multi-color LED lighting in homes is a growing industry as well. You can change colors, even program sequences, within a room or rooms. I am not sure if it's the same technology but in the mid eighties I saw Hall and Oates. They had some brand new, super top secret color changing spots by SoundCo if I remember correctly. At the time they were the talk of the lighting industry... It's doubtful that whatever they used was like what is now available. There have been tremendous strides made with solid state, light emitting diodes in the past few years. One of my music friends owns the largest backstage equipment rental company in New England and supplies stage lighting equipment along with sound systems, amps, guitars, keyboards and B-3 organs to all the major performance venues in the Boston and surrounding areas. I was at his warehouse last year because he was donating some equipment for the performance venue I was building. He showed me all the newer stage lighting, wall wash and spotlight systems he uses. All are LED based systems. These are big, industrial systems but use the same basic technology as the systems available for general consumer use. Again, the driver is the fractional power they require while still generating the same level of lighting. The fact that they are individually programmable is also a huge advancement. One fixture can generate any color you want and can be controlled by midi or other programing techniques to generate a light show that compliments a performance by a band or musician. Look into "SoundCo" in the Eighties, or ask your friend. Whatever those lights were they may have been early led's.... I know the company was very secretive about them and at the time a company rep accompanied the systems and "you" were really not allowed to work on one or dis-assemble them. At the time "the talk" was that if you tried to take one apart, they were designed to emplode to mask the technology but that was probably just rock and roll, smoke and mirrors... |
