Mitch Gross Posted March 26, 2008 Share Posted March 26, 2008 Excellent lumens to watts ratio. Super efficient. I wonder what the CRI is like and if it has a flicker discharge. Also if they can make it any lower in power. Link to comment Share on other sites More sharing options...

Premium Member John Sprung Posted March 26, 2008 Premium Member Share Posted March 26, 2008 Here's the specs from their web site: http://www.lifi.com/pdfs/ProductBulletinLIFI.pdf It looks quite good, there are no spikes in the spectrum, but it does have a couple strange notches at 411 and 452 nm. CRI is claimed to be 88 - 95. Flicker should be no problem, as it's operating in the RF range. It does look expensive to make, and may initially only be cost effective for high power applications. With no electrodes in the bulb, life should be quite long, and I don't see any reason for it to degrade over its life. They say it's still 80% at 25,000 hours. There's no mention of prices. I guess like J.P. said, if you have to ask, you can't afford it. -- J.S. Link to comment Share on other sites More sharing options...
Drew Ott Posted March 26, 2008 Share Posted March 26, 2008 Sounds promising. Even if it does cost a fortune, won't it drive down the prices of current light sources? Link to comment Share on other sites More sharing options...
Michael Collier Posted March 27, 2008 Share Posted March 27, 2008 They say its 6000k, so even if its really expensive, so is HMI. It might be competitivly priced once its out. smaller bulb = smaller point light which means sharper shadow detail from an open face or fresnel.

Premium Member John Sprung Posted March 27, 2008 Premium Member Share Posted March 27, 2008 They say its 6000k, so even if its really expensive, so is HMI. The CIE coordinates they give for it land closer to 6600K, though they say 6400K. Production volume will determine the cost. It looks to be comparable to HMI when they get up to the same volume. -- J.S. Link to comment Share on other sites More sharing options...
Serge Teulon Posted March 27, 2008 Share Posted March 27, 2008 Was the blue rimmed, white centred beam on the wall from our 'bulb'? S Link to comment Share on other sites More sharing options...
Chayse Irvin ASC, CSC Posted March 27, 2008 Share Posted March 27, 2008 Wow. That is amazing. It would probably give a beam as sharp as a carbon arc. but that will depend on the reflector behind it. Link to comment Share on other sites More sharing options...
Premium Member Michael Nash Posted March 27, 2008 Author Premium Member Share Posted March 27, 2008 I can't wait to call for a "6K PlasmaBeam"... Link to comment Share on other sites More sharing options...
Premium Member John Sprung Posted March 27, 2008 Premium Member Share Posted March 27, 2008 .... but that will depend on the reflector behind it. One of the peculiarities of this technology is that the tiny globe has to be mounted in the side of a big block of material. It might not put any light behind the plane of that surface. It has to do with getting the RF energy into the globe. -- J.S. Link to comment Share on other sites More sharing options...
Mike Simpson Posted March 29, 2008 Share Posted March 29, 2008 I can't wait to call for a "6K PlasmaBeam"... [/quote I agree. The need a more futuristic nickname though. Link to comment Share on other sites More sharing options...
Mitch Lusas Posted March 30, 2008 Share Posted March 30, 2008 140 lumens per watt!!! And they're so small. I would love to be on the first shoot that was able to use them. Link to comment Share on other sites More sharing options...
Premium Member Walter Graff Posted March 30, 2008 Premium Member Share Posted March 30, 2008 In the next 6 months to a year some more pretty amazing light sources are going to be introduced so hang in there. And light sources more for use in our industry. This light source is more industrial than for film. Link to comment Share on other sites More sharing options...
Premium Member Chris Keth Posted March 31, 2008 Premium Member Share Posted March 31, 2008 That looks promising. I don't know the things involved in powering it, but I can see some serious fixtures using this technology pretty quickly if they are efficient and tough enough. A cluster of these would be nice in a china ball, for example. Link to comment Share on other sites More sharing options...
