I have found a few sources for these lights. I have yet to receive any replies from the companies so I will wait to make sure they are legit and can supply the lights at retail befor I put there contact up. If these places are legit they are charging $1000. for the microwave sulphur lights.

If, in fact, they stopped being produced due to interference with wireless transmissions, that sounds like maybe the funding for furthur research was pulled because of other reasons. Conspiracy maybe? Or, more likely the research kept going but the media lost all interest so we don't here anything about new advances anymore.

There has been one advancement (at least) that has been publicized. It is an additional element added to the sulphur to create another spike in the wavelength of light available. I am unable to find the link right now. If I find it again I will post it. It basically explains how different elements can be used to tailor the output of a microwave powered lamp.

FERMENTATION Reviewed by FERMENTATION on . sulphur plasma lighting Well, it seems I need to recreate my overgrow thread here. This is about the sulphur plasma lamp. It is a technology developed by NASA as a replacement for sunlight for deep space vehicles. In PAR ratings it equals or rivals the sun and yet puts off almost no heat. It flat blows the doors off of current indoor plant lighting HID in PAR, waste heat and energy efficiency! The price for them is about $1600 USD and they can be purchased at http://www.nurturelite.com/photoponics.htm. As far Rating: 5
