The best light bulb used by the US government is the micro voltage sulpher bulb. In the base a micro voltage microwave generator stimulates sulpher molecules in the bulb to produce a virtual heat free light that is powerful and 99.5% the spectrum of natural sunshine. They use these bulbs in the museums on the Washington Mall such as the Air and Space Museum.



These bulbs were invented in Germantown MD 12 years ago but it is my suspicion that they may have been bought out by Phillips Corp.

Indoor growers would love to get ahold of these bulbs. The DEA would hate for this to happen since infra red cameras would be useless in dectecting large indoor growing facilities that used this bulb.

So we are left with the highly toxic Mercury flourescent bulbs partly for the same reason that we have Flouride in the water.

It is CHEAPER to incorporate highly toxic substances in a new product or process than it is to safely dispose of highly toxic materials.
