Here's a very positive article in LA times (just change your browser to private setting if you have problems reading) on HIVE plasma lights, with some pretty grand claims (color rendition almost as good as the sun etc.), supposedly super efficient etc.

"Plasma lights, more often used in street lamps and medical imaging, breeze past the color-quality problems in LED lights. They last as much as 30 times longer than conventional hydrargyrum medium-arc iodide lights — a perk on months-long film shoots with 18-hour days.Plasma lights can reduce on-set energy usage by 50% and power costs by about 40%, Miller said. And perhaps the most crucial advantage in an industry driven by aesthetics, plasma lights won't flicker, and they cover the full color spectrum while conventional lights lack certain shades.
Jay Hunter, director of photography on Joss Whedon's "Much Ado About Nothing," used Hive's lights when the indie film's shoestring budget required the crew to shoot without a generator.
"They don't replace the lights that are out there completely," Hunter said. "The sun is the best color-rendering index possible, but the plasma lights approach that level of perfection."
