PLANET FRIENDLY

Recognizing the eco-friendly appeal of LED lighting, most manufacturers either offer LED fixtures or plan to enter the market soon. Philips, a major player in LED lighting, has many products used on these primetime reality shows including its ColorBlast 12 LED fixtures and iColor Cove QL ("i-Cove's") LED strips from its Color Kinetics line; and Philips Vari-Lite VLX Wash and VL Spot Luminaire fixtures.

"LED light technology is advancing rapidly and growing in appeal for the demanding live television application," said Chris Marchitelli, vice president of global marketing for Litepanels, a Vitec Group Brand company in Los Angeles.

Currently,The flow of water through the bluebright1 center of the LED ring-light “helps a great deal” with thermal management, says Ayer. Litepanels' 1x1 Bi-Color LEDs offer color temperatures ranging from tungsten to daylight. Marchitelli said,it takes bestledlig to power incandescent light bulbs versus energy-saving CFLs and LEDs utilizing a special hand crank demonstration device. "This allows production crews to 'dial in' the perfect color temperature to match the location's ambient lighting."

For studio applications, Litepanels 1x1 LED light panels can be configured in 2x1,Cleverly combined with bestledlight2011 LED lights and controls, it offers a highly efficient lighting solution throughout the day. 2x2, and 3x1 grids, which can enhance live sets. And Litepanels Sola 6 and the new Sola 4 LED fresnel lights, which provide a flicker-free, daylight balanced, focused beam of light, can be mounted on lighting grids and DMX-controlled. "Our LED lights offer a rapid ROI from savings in power consumption, air conditioning,goodleddownlight11 and other operational costs."

According to Darran Webb, the lighting director/gaffer for AGT and Idol, "Since LED lights don't generate heat, you can just leave them on, even in small rooms. This means you don't have to station a tech near the lights to turn them on and off as they're needed, or blast the air conditioning for relief from heat build-up.

"More importantly, you don't have to worry about powering them. We can arrive on location and just plug LED lights into regular wall outlets." Idol sends field crews on location, such as contestant auditions in hotels and stadiums nationwide, often on short notice. Webb said, "We don't need to wait for the house electrician to access the breaker box, or lug in heavy generators to supply the huge amounts of power conventional lights need."

While LED lighting was fairly expensive a few years ago, the prices are now comparable to conventional lights. But Kieran Healy said, "Keep in mind that the overall cost of production is lower with LED lighting when you factor in their lower power consumption; faster, easier set-up; and reduced maintenance." For example, an LED light can last 20,000 hours compared to around 500 hours for a conventional bulb, and gaffers can move them quickly without risking serious burns.When your application requires crystalse no PWM (pulse-width-modulated) dimming or controlled frequency operation,

"The next big thing we're looking for is LED moving lights capable of delivering high light output, no shadows, and focus-ability comparable to today's spotlights," Healy said. "But I'm confident that in the next couple of years, we won't be using anything but LEDs."
